74HC595PW/AUJ

Overview

The 74HC595PW/AUJ is an 8-bit serial-in, serial/parallel-out shift register manufactured by NXP USA Inc. It features a storage register with parallel outputs and operates within a supply voltage range of 2 V to 6 V. The device utilizes CMOS technology and is housed in a TSSOP-16 package (SOT403). It supports cascading via a serial output and includes asynchronous reset functionality. The component is designed for surface-mount installation and functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides serial-to-parallel data conversion using separate shift and storage registers.
• Features three-state parallel outputs controlled by an active-low enable signal.
• Supports cascading through a dedicated serial output pin for expanded I/O capabilities.

Applications

• General-purpose digital logic interface circuits
• Microcontroller peripheral expansion systems
• LED display driver matrices

Procurement Notes

Verify the specific suffix AUJ against official Nexperia documentation to confirm tape-and-reel packaging or variant specifications. Ensure compatibility with standard 74HC logic families regarding voltage levels and timing requirements before integration into existing designs.

Selection Notes

Select this component when a robust 8-bit shift register with high noise immunity is required. The HC series offers wide voltage operation suitable for mixed-voltage systems. Consider the TSSOP package dimensions for PCB layout constraints and verify thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the widely adopted 74HC family of high-speed CMOS logic devices. It serves as a standard solution for converting serial data streams into parallel formats in embedded systems. The device is commonly used in conjunction with microprocessors to manage multiple output lines efficiently.

Replacement Considerations

Compatible substitutes include SN74HC595 from Texas Instruments and MC74HC595A from onsemi. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.
