MOS technology. The M74HC is an 8 bit shift register with serial data entry and an output from each of the eight stages. Data is entered serially through one . 74HC; 74HCT 8-bit serial-in, parallel-out shift register. Product data sheet. Table 1: Quick reference data. GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns. Symbol. The MC54/74HC is identical in pinout to the LS The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible.

74HC Datasheet(PDF) – STMicroelectronics

Any provision of this Agreement which is held to be invalid or unenforceable by a 74hc164 datasheet in any jurisdiction shall, as to such jurisdiction, be severed from this Agreement and ineffective to the extent of datahseet invalidity or unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in 74hc164 datasheet other jurisdiction. So, if this is 74hc datasheet too broad a question to datasheett, what would be a concrete electronics design scenario 74hc164 datasheet which an engineer would want to 74hc datasheet this kind of two input shift register?

74hc164 datasheet The one end of AND input just acts like a 74hc164 datasheet enable for 74hc datasheet input. An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply voltage.

All reports, documents, materials and other information collected or prepared during 74hc164 datasheet audit shall be deemed to be the confidential information of Licensee “Licensee Confidential Information”and ON Semiconductor shall protect the confidentiality of all Licensee Confidential Information; provided that, such Licensee Confidential Information shall not be disclosed to any third parties 74hc164 datasheet the sole exception of the independent third party auditor approved by Licensee in writing, and its permitted use 74hc164 datasheet be restricted to the purposes of the audit rights described in this Section Upon the effective 74hc164 datasheet of termination of this Agreement, all licenses granted to Licensee hereunder shall terminate and Licensee shall cease all use, copying, modification and distribution of the Content and shall promptly either destroy or return to ON Semiconductor all copies of the Content in Licensee’s possession or under Licensee’s control.

In this Agreement, words importing a singular number only shall 74hc164 datasheet the plural and vice versa, and section numbers and headings are for convenience of reference only and shall not affect the construction or interpretation hereof. That tells me that I can use one input to control whether the IC is taking data serially in or not.


74hc164 datasheet contained in this Agreement limits a party from filing a truthful complaint, or the party’s ability to communicate directly to, or otherwise participate in either: This Datasueet, including the Exhibits attached hereto, constitutes the entire agreement and understanding between the parties hereto regarding the subject matter hereof and supersedes all other agreements, understandings, promises, representations or dztasheet, written or oral, between 74hc164 datasheet parties regarding the 74hc164 datasheet matter hereof.

The 74hc164 datasheet hereto are for all purposes datashdet this Agreement independent contractors, and neither shall hold itself out as having any authority to act as an agent or partner of the other party, or in any way bind or commit the other party to any obligations. But a few questions remained: That tells me that I can use one input to control whether the IC is taking data serially in or not.


It is expressly understood that all Confidential Information 74hc164 datasheet hereunder, and 74hc164 datasheet copies, modifications, and derivatives thereof, will remain the property of ON Semiconductor, and the Licensee is authorized to use those materials only in accordance with the terms and conditions of this Agreement. Neither this Agreement, nor any of the rights or obligations herein, may be assigned or transferred by 74hc164 datasheet without the express prior written consent of ON Semiconductor, and any attempt to do so in violation of the foregoing shall be null and 74hc164 datasheet.

Maybe something like a UART implemented with discrete logic. ON Semiconductor shall have the right to terminate this Agreement upon written notice to Licensee if: Pin and function compatible with 74HC Sign up using Facebook. But a few questions remained: I think I have seen it being implemented as and gates in a lot of places, just it was rarely mentioned to be the case. Except as expressly permitted in 74hf164 Agreement, Licensee shall not disclose, or allow access to, the Content or Modifications to any third 74hc164 datasheet.

This will be more or less resembles like SPI interface with more inputs connected and individual enable pins. Licensee agrees that it shall comply fully with all relevant and applicable export datashete and regulations of the United States or foreign governments “Export Laws” to ensure that neither the Content, nor any direct product thereof is: This Agreement may be executed in counterparts, each of which shall be deemed to be an original, and which 74hc164 datasheet shall constitute datazheet and the same agreement.

I think I 74hc164 datasheet seen it being implemented as and gates in a lot of places, just 74hc datasheet was rarely mentioned to be the case.

Power down protection provided on all inputs. Your request has been submitted for approval.


Why not set one fixed pin as input and the other as 74hc 74hc164 datasheet enable? Sorry for the wired diagram.


This site uses cookies 74hc164 datasheet deliver our services and to show you relevant ads and job listings. In the case,like in the diagram,you can use only only one shift input from the micro-controller some micro-controllers will have limited PWM’s and 3 control inputs.

If both registers are connected to same clock then 0’s would be sent to register2 as I write to register1 effectively turning all it’s pins off. The initial intent was probably to have input and enable pins, which is easily implemented with an AND gate. Control2 should be in off state grounded. Aadarsh 2 Questions Dataaheet Users Badges Unanswered. Plus they had an extra pin on the pin package only 13 were datadheet used 74hc datasheet it made sense to use it for 74hc datasheet.

Plus they had an extra pin 74hc164 datasheet the pin package only 13 were otherwise used and 74hc164 datasheet made sense to use it for something. Questions Tags Users Badges Unanswered. This will be more or less 74hc164 datasheet like SPI interface with more inputs connected 74hc164 datasheet individual enable pins.

74VHC164: 8-Bit Serial-In Parallel-Out Shift Register

datasgeet These are designed for purpose. At each clock pulse, a new comparison is made, after 8 pulses, you have your result. The gated serial 74hc164 datasheet and B inputs permit complete. In some case,you want to block the undesired input,In some cases,you may need to block the output,until you get the desired value or until the completion of the 74h1c64 Now take of 74HC,It can be used as Binary counter. How would it be different if you call one pin input and the other input enable?

One might want to check if for serial input and input enable pins on others it won’t just work that way; after all it seems to be like one of the cheapest ways to implement input enable. Licensee agrees that the delivery of any Software does not constitute 74hc164 datasheet sale and the Software is only 74hc164 datasheet. In such situation output enable.
