SN74AHC595PW

Shift Registers Overview

The SN74AHC595PW is an eight-bit serial-in, parallel-out shift register from Texas Instruments' AHC logic family. It operates on a single power supply ranging from 2 V to 5.5 V and features three-state outputs. The device utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package with surface-mount installation. It supports serial data input through a dedicated pin and includes a storage register for parallel output latching. The component functions with rising-edge clock triggers and maintains reliable operation across an extended industrial temperature range of -40 °C to +125 °C.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities using a single serial input line.
• Features three-state outputs that allow direct connection to bus-oriented systems.
• Includes separate clock inputs for the shift register and storage register to control data timing independently.

Shift Registers Applications

• LED display matrix scanning and multiplexing circuits
• Industrial I/O expansion modules for microcontroller systems
• Consumer appliance control interfaces requiring additional output pins

Shift Registers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure the ordering part number matches the required SOIC-16 configuration. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when designing systems requiring low-power CMOS performance with wide voltage flexibility. The AHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 5-V systems. Consider the extended temperature range if the application environment exceeds standard commercial limits.
