About this product
The 74HC164 is an 8-bit serial-in, parallel-out shift register with an asynchronous master reset. Data is clocked in one bit at a time, and the eight parallel outputs can be used to drive loads within the chip's ratings or to read states. It is useful for adding outputs while saving microcontroller pins.

Frequently asked questions
How is the 74HC164 different from the 74HC595?
The 74HC164 has no output storage latch, so its outputs change as data shifts in. The 74HC595 has a separate latch clock that holds the outputs stable while new data is shifted in.
What do I do with the two serial inputs on the 74HC164?
The 74HC164 has two data inputs, A and B, which are combined with a logic AND. Connect both to your data line, or tie the unused one HIGH so that the other acts as the data input.
