Product Introduction

Overview

The SN74HC594N, produced by Texas Instruments, is an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. This device is part of the HC (High-Speed CMOS) logic family and is designed for a wide range of digital applications. It features separate clocks for both the shift and storage registers, along with direct overriding clear inputs (RCLR, SRCLR) for each register. The shift register and storage register clocks are positive edge triggered, allowing for synchronized data transfer. The device also includes a serial output (QH’) for cascading multiple shift registers.
