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.

This Agreement may be executed in counterparts, each of which shall 74hc164 datasheet deemed 74hc164 datasheet be an original, and which together shall constitute one and the same agreement. The remedies herein are not exclusive, but rather are cumulative and in addition to all other remedies available to ON Semiconductor.

The one end of AND input just acts like a input enable for the input. Any provision of this Agreement which is held to 74hc164 datasheet invalid or unenforceable by a court in any jurisdiction shall, as to such jurisdiction, be severed from this Agreement and ineffective to the extent of such invalidity or unenforceability 74hc164 datasheet invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.


74hc164 datasheet a few questions remained:. Why not set dataeheet fixed pin as input and the other as input enable? You will receive an email when your request fatasheet approved. The spec could just have listed one pin as input and the other one as enablebut 74hc164 datasheet AND operation is commutative, it was decided to expose that implementation detail in the spec and label the pins dsa and dsb to reflect that.


Datashedt some case,you datasheeet 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 clock Now take of 74HC,It can be used as Binary counter.

The device 74hc164 datasheet an asynchronous Master Reset which clears the register, setting all outputs LOW independent dataxheet the clock. In your last diagram, assuming I am trying to write data to shift register1 only. But a few 74hc164 datasheet remained: I think I have seen it being implemented as and gates in a lot of places, just 74hc164 datasheet was rarely mentioned to be 74hc164 datasheet case. Sorry for the wired diagram.

At each clock pulse, a new comparison is made, after 8 pulses, you have your 74hc datasheet. You can consider the input pin like this In some shift 74hc164 datasheet like 74HC there is a output enable pin. Upon the effective date of termination of this Agreement, all licenses granted to Licensee hereunder shall terminate and Licensee shall cease all use, copying, modification and distribution of 74hc164 datasheet Content dataasheet shall promptly either destroy or return to ON Semiconductor all copies of the 74hc164 datasheet in Licensee’s possession or under Licensee’s control.

Am I missing something? This will be more or less resembles like SPI interface with more inputs connected and individual enable pins.


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 74hc164 datasheet to be like one of the cheapest ways to implement input 74hc164 datasheet.

This always allows flexibility 74hc164 datasheet us. Humm — Now I get it, many thanks! Am I missing something? EM Fields 16k 2 74uc Consider the following diagram.

Power down protection provided on all inputs. Right, but they’re naturally interchangeable so hiding that datasheft seems like it’s 74hc164 datasheet of any value. 74hc164 datasheet top of that, the two inputs go through 74hc datasheet AND gate, as in the picture below figure 1 on the datasheet: I think I have seen it being implemented as and gates in a lot of places, just 74hc datasheet was rarely mentioned to be the case.

Your request has been submitted for approval. 74hc164 datasheet they had an extra pin on the pin package only 13 were otherwise used and it made sense to use it for something.

These are designed for purpose. Previously Viewed Products Select Product I did google 74hc164 datasheet an answer, but didn’t get any meaningful results.

How would it be different if you call one pin input and the other input enable?
