Detailed Description

8-bit serial-in, serial/parallel-out shift register with storage register and 3-state outputs. CMOS 74HC family. Wide supply range 2 V to 6 V. Single element, 16‑lead SSOP package, tape-and-reel. Operating temperature −40°C to +85°C. RoHS3 compliant. Base product number 74HC595. Series 74HC. Function serial to parallel and serial cascading.

Key Features

8-bit shift register plus 8-bit storage register (latch)

Serial data in, parallel 8-bit outputs, serial data out for easy daisy-chain

3-state outputs enable bus sharing

Wide VCC range 2 V to 6 V for 3.3 V or 5 V systems

CMOS 74HC logic family for low power and good speed

Standard control pins OE, MR, SHCP, STCP for simple MCU/FPGA interfacing

Surface-mount 16-SSOP for compact layouts

Industrial temperature grade −40°C to +85°C

RoHS3 compliant lead-free terminals

Key Advantages

Reduces MCU/FPGA pin count by converting serial to parallel lines

Easy cascading allows large channel counts with minimal pins

Works across common logic rails (3.3 V and 5 V)

Tri-state outputs simplify bus multiplexing and isolation

Mature, widely used device with abundant design resources

Compact SSOP footprint saves board space while remaining assembly-friendly
