Product Overview
The SN74HC164NS is a high-speed 8-bit serial-in, parallel-out shift register from Texas Instruments (TI), housed in a 14-pin SO package. It operates over a wide voltage range of 2V to 6V, making it suitable for various logic-level applications. The device features two serial data inputs (A and B) that can be used as independent data inputs or combined for higher drive capability. Data is shifted on the positive-going edge of the clock (CP), and a master reset (MR) input clears the register asynchronously.
