8-bit Shift Register – SN74HC164N


18 in stock



A shift register is a device that can record the state of an input a number of times and output each one of the recordings on separate pins. Imagine reading a binary value and writing it down on a piece of paper, then setting some switches to the state of the binary value. for example:

147 = 10010011

so the outputs would be:

1   0   0   1   0   0   1   1

This generates a serial to parallel converter. Serial data is clocked into the register. Parallel data is outputted.
The output can also be latched and disabled, so the output will stay the same whilst new data is being clocked in and the output can be disabled if you have multiple registers connected to the same bus.
