74HC595 - serial or parallel-out shift register

General Description

The 74HC595; 74HCT595 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.

Both the shift and storage register have separate clocks.

Key Features

74HC595; 74HCT595 8-bit serial-in, serial or parallel-out shift register with output latches; 3-state Rev. 12 — 20 March 2024 Product data sheet 1. General description The 74HC595; 74HCT595 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. Both the shift and storage register have separate clocks. The device features a serial input (DS) and a serial output (Q7S) to enable cascading and an asynchronous reset MR input. A LOW on MR will reset the shift register. Data is shifted on the LOW-to-HIGH transitions of the SHCP input. The data in the shift register is transferred to the storage register on a LOW-to-HIGH transition of the STCP input.
