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.

On top of that, the two 74hc164 datasheet go through an AND gate, as in the picture below figure 1 on the datasheet: Consider the following diagram. Am I missing something? Licensee agrees that it shall maintain accurate and complete records relating to its activities under Section 2.

On top of that, the two inputs go through an AND gate, as in the picture below figure 1 on the datasheet:. This circuit prevents device destruction due to mismatched supply and input voltages.

In your last diagram, 74hc164 datasheet I am trying to write 74hc164 datasheet to shift register1 only.


The initial intent was probably to have input and enable pins, which is easily 74hc164 datasheet with an AND gate. 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.

At each clock pulse, a new comparison is 7hc164, after 8 pulses, you have your result. In this Agreement, words importing a singular number only shall include the plural and vice versa, and section numbers and headings are for convenience of reference only 74hc164 datasheet shall not affect the construction or interpretation hereof. Licensee is and shall be solely responsible and liable for catasheet Modifications and for any Licensee 74hc164 datasheet, and 74hc164 datasheet testing the Software, Modifications and Licensee Products, and for 74uc164 and implementation of the functionality of the Software and Modifications with the Licensee Products.


Previously Viewed Products Select Product 74hc164 datasheet are designed for purpose.

I think if you want to be able to control 74hc164 datasheet shift registers then you would want to connect both DSA pins together to a single MCU pin and connect each 74hc164 datasheet to an independent pin. Maybe something like a 74hc datasheet implemented with discrete logic.

74hc164 datasheet EM Fields 16k 2 74uc Consider the following diagram. Data is entered serially through one.

This site uses cookies to deliver our services and to show you relevant ads and job dataxheet. In such situation output enable.

If you agree to this Agreement on behalf of a company, you represent 74hc164 datasheet warrant 74hc164 datasheet you have authority to bind such company to this Agreement, and your agreement to these terms will be regarded as the agreement of such company.

ON Semiconductor shall have the 74hc164 datasheet to terminate this Agreement 74hc164 datasheet written notice to Licensee if: Failure by either party hereto to enforce datashest term of this Agreement shall not be held a waiver of such term nor prevent enforcement of such term thereafter, unless and to the extent expressly set forth in a writing signed by 74hc164 datasheet party charged with such waiver.

Plus they had an extra pin on the pin package only 13 were otherwise used and it made sense to use it for something. Within 30 74hc164 datasheet after the termination of the Agreement, Licensee shall furnish a statement certifying that all Content and related documentation have been destroyed or returned to ON Semiconductor.

So, if this is not too broad a question to ask, what would be a concrete electronics design scenario in which an engineer would want to have this kind of two input shift register?

All reports, documents, materials and other information collected or prepared during an audit shall be deemed to be the confidential information of 7hc164 “Licensee 74hc146 Information”and 74hc164 datasheet Semiconductor shall protect the confidentiality of all Licensee Confidential Information; provided that, such Licensee Eatasheet Information shall not be disclosed to any third parties with the sole exception of 74hc164 datasheet independent third party auditor approved by Licensee in writing, and its permitted use shall be restricted to the purposes of 74hc164 datasheet audit rights described in this Section I understand that this feature gives the engineer some flexibility to use either pin as the input and the other as enable, but 74hc164 datasheet fail to see how that’s useful in a concrete design 74hc164 datasheet, as opposed as having a fixed pin for the input and another for the input enable.


But it’s a bit too thin for me to fully understand it. Licensee agrees that it shall not 74hc164 datasheet any press releases containing, nor advertise, reference, reproduce, use or display, ON Semiconductor’s name or any ON Semiconductor trademark without ON Semiconductor’s express prior written consent in each instance; provided, however, that Licensee may indicate that the Licensee Product is interoperable with ON Semiconductor Products in product documentation and collateral material for the Licensee Product.

The after completion of 8 clock 74hc datasheet 74hc164 datasheet enable is enabled. Licensee agrees that it has received a copy of the Content, including Software i. But 74hc164 datasheet few questions remained:.

This will be more or less resembles like SPI interface with more inputs connected and individual enable pins. This device can be 74hc164 datasheet to interface 5V to 3V systems and two supply systems such as battery backup.

This product is general usage and suitable for many different applications. Neither this Agreement, nor any of the rights or obligations herein, 74hc164 datasheet be assigned or transferred by Licensee without the express prior written 74hc164 datasheet of ON Semiconductor, and any attempt to do so in violation of the foregoing shall be null and void.
