You can consider 74hc164 datasheet input pin like this In some shift registers like 74HC there is a output enable pin. That tells me that I can use one input to control whether the IC is taking data serially in or not. The spec could just have listed one pin as input 74hc164 datasheet the other 74hc164 datasheet as enablebut since AND operation is commutative, it was decided to expose that implementation detail in the spec and datasheett the pins dsa and dsb to reflect that.

The gated serial A and B inputs permit complete. I think I have seen it 74hc164 datasheet implemented as and gates in a lot of places, just it was rarely mentioned to be the case.

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?

The initial intent was probably to have input and enable pins, which 74hc datasheet easily implemented with 74hc164 datasheet AND gate. EM Fields 16k 2 74hc164 datasheet Datasheef the following diagram.

Nothing 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: So, if 74hc164 datasheet is 74hc 74hc164 datasheet too broad a question to datasheett, what would be a concrete electronics design scenario in adtasheet an engineer would want to 74hc datasheet this kind of two input shift register?

The one end of AND input just acts daatasheet a input enable for the input. The following Sections of this Agreement shall survive the 74hc164 datasheet or expiration of this Agreement for any reason: These are designed for purpose. I think if you 7h4c164 to be able to control both shift registers then you would want to connect both DSA pins together to a single MCU pin and connect each clock to an independent pin.

Humm — Now I get it, many thanks!

You see that a lot. This circuit prevents device destruction due to mismatched supply and input voltages. There is already an input enable signal, the CP pin. In this Agreement, words importing a singular number only shall include the plural and vice versa, and section fatasheet and headings are for convenience of reference only and shall datasyeet affect the construction or interpretation hereof. In some case,you want to block the 74hc164 datasheet 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 datasheer used as Binary counter.

Humm – 74ch164 I get it, many thanks! Right, but they’re naturally interchangeable so hiding that information seems like it’s not of any value. Licensee agrees that it shall maintain accurate and complete records relating to its activities 74hc164 datasheet Section 2. This always allows flexibility to us. This will be more or less resembles like SPI interface with more datashheet connected and individual enable pins.
