SN74HC595DRG4

Shift Registers Overview

The SN74HC595DRG4 is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the SN74HC logic family and features Schmitt-trigger inputs for noise filtering. The device includes a storage register with 3-state outputs, allowing data transfer from the shift register to the output latches via a separate clock. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 16-SOIC package.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel data conversion capability
• Features Schmitt-trigger inputs to improve noise immunity
• Includes a storage register with 3-state outputs for bus driving

Shift Registers Applications

• Industrial control systems requiring I/O expansion
• Consumer electronics utilizing LED displays or indicators
• General-purpose digital logic interfacing applications

Shift Registers Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to the intended RoHS-compliant variant as defined by Texas Instruments documentation. Confirm that the 16-SOIC package dimensions match the target PCB footprint requirements. Ensure compatibility with the system's operating temperature range and voltage levels before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with high-noise immunity is required. The Schmitt-trigger inputs make it suitable for environments with signal integrity challenges. Compare against standard HC variants if higher speed or different voltage thresholds are needed, noting that this part offers robust input characteristics for reliable operation across the specified voltage range.

Shift Registers Part Context

This component is part of the SN74HC series of high-speed CMOS logic devices produced by Texas Instruments. It serves as a fundamental building block for digital systems needing serial data expansion. The DRG4 designation indicates a specific tape-and-reel packaging format compliant with environmental standards, distinct from other package types like PW or NS.
