Product Overview
The SN74LV164D is a high-speed, low-power 8-bit serial-in, parallel-out shift register from Texas Instruments. It operates over a wide supply voltage range of 2V to 5.5V, making it suitable for battery-powered and industrial applications. The device features two serial data inputs (A and B) that are ANDed to provide a single serial input, and eight parallel outputs (Q0–Q7). Data is shifted on the rising edge of the clock (CLK) and an asynchronous master reset (MR) clears the register.
