SN74AHC594DR TI Shift Register | 16-SOIC | 8-bit, Serial-In/Parallel-Out

Product Overview

The SN74AHC594DR from Texas Instruments is an 8-bit shift register with output latches and 3-state outputs. It features a serial input (SER) and a shift register clock (SRCLK) for data entry, and a storage register clock (RCLK) for transferring data to the output latches. The device operates over a wide supply voltage range of 2 V to 5.5 V, making it suitable for battery-powered and low-voltage applications. The 3-state outputs allow for bus-oriented applications. The SN74AHC594DR is offered in a 16-pin SOIC package, providing a compact solution for digital systems requiring parallel data output from a serial data stream.
