Product Overview
The SN74HC164DT from Texas Instruments is a high-speed 8-bit serial-in, parallel-out shift register fabricated using advanced silicon-gate CMOS technology. It operates from 2V to 6V and features low power consumption, making it ideal for a wide range of digital applications. The device accepts serial data input and provides parallel output through eight stages, with a master reset function to clear the register. Housed in a compact 14-SOIC package, it is suitable for space-constrained designs.
