74HC595; 74HCT595

8-bit serial-in, serial or parallel-out shift register with output

latches; 3-state

Rev. 11 — 10 September 2021

Product data sheet

1. General description

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

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. If both clocks are connected together, the shift

appears at the output whenever the output enable input (OE) is LOW. A HIGH on OE causes the

outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the

state of the registers. Inputs include clamp diodes. This enables the use of current limiting resistors

to interface inputs to voltages in excess of V_CC
