The 74AHC164 and 74AHCT164 are 8-bit serial-in/parallel-out shift registers and are classified as high speed silicon-gate CMOS devices. These devices are pin compatible with Low-power Schottky TTL ...

This Design Idea shows how a single microcontroller port can drive a lot of output lines through shift register. In this case we use the shift register with strobe control to achieve perfect output ...
