CD74HC595DW TI Shift Register | 16-SOIC | 8-Bit, Serial-In Parallel-Out

Product Overview

The CD74HC595DW from Texas Instruments is a high-speed CMOS 8-bit shift register with output latches and three-state outputs. It features a serial input (SER), a shift clock (SRCLK), a storage register clock (RCLK), and an output enable (OE). The device converts serial data to parallel output, making it ideal for expanding microcontroller I/O lines. Operating from 2V to 6V, it offers low power consumption and high noise immunity. The 16-SOIC package is suitable for surface-mount applications.
