SN74LV165AD TI Shift Register | 16-SOIC | 8-Bit, Parallel-In, Serial-Out

Product Overview

The SN74LV165AD from Texas Instruments is an 8-bit parallel-in, serial-out shift register designed for low-voltage (2V to 5.5V) operation. It features a wide operating voltage range, low power consumption, and high noise immunity, making it ideal for a variety of digital applications. The device accepts parallel data inputs and outputs data serially, controlled by a shift/load input and a clock input. The SN74LV165AD is available in a 16-pin SOIC package, offering a compact solution for expanding digital inputs in microcontroller-based systems.
