8-bit serial-in parallel-out shift register
The 74AHCT164PW112 is an 8-bit serial-in parallel-out shift register — a logic IC that takes a serial data stream on one input and presents the latched data on eight parallel outputs. This is the part you reach for when you need to expand a microcontroller's output pins or drive a segmented display without tying up a GPIO per segment.
