SN74AHCT594DBR TI Shift Register | 16-SSOP | 8-Bit, Serial-In, Parallel-Out

Product Overview

The SN74AHCT594DBR 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 clock (SRCLK) for data entry, and a storage register clock (RCLK) for transferring data to the output latches. The device operates over a wide voltage range of 4.5 V to 5.5 V, making it suitable for 5V TTL logic systems. Housed in a compact 16-SSOP package, it is ideal for space-constrained applications.
