SN74HC595PWR

Shift Registers Overview

The SN74HC595PWR is an 8-bit serial-in, parallel-out shift register from Texas Instruments' HC logic family. It features a storage register with tri-state outputs and operates within a wide supply voltage range of 2 V to 6 V. The device utilizes a TSSOP-16 surface-mount package and supports propagation delays as low as 34 ns. Designed for CMOS technology, it offers high noise immunity and low input current characteristics suitable for general-purpose digital logic applications.

Shift Registers Feature Summary

• Serial-to-parallel data conversion capability via dedicated shift and storage registers
• Tri-state output control allowing multiple devices to share bus lines without interference
• Direct clear function enabling immediate reset of the storage register state

Shift Registers Applications

• LED display matrix scanning systems
• Industrial I/O expansion modules
• Consumer electronics peripheral interfacing

Shift Registers Procurement Notes

Verify the specific suffix PWR confirms the TSSOP-16 package and reel packaging format. Ensure compatibility with standard 5V or 3.3V logic levels by confirming the operating voltage range meets system requirements. Check RoHS compliance status if environmental regulations apply to the final assembly process.

Shift Registers Selection Notes

Select this component when a compact 8-bit shift solution is required in a small outline package. The HC series provides a balance of speed and power consumption suitable for battery-operated or noise-sensitive environments. Consider the tri-state feature if bus multiplexing is necessary for the design architecture.

Shift Registers Part Context

This part belongs to the widely adopted SN74HC595 family, serving as a standard interface between microcontrollers and external peripherals. It replaces older bipolar logic families with lower power consumption while maintaining compatible pinouts for legacy board designs. The TSSOP variant offers space efficiency for modern dense PCB layouts.
