SN74HC595DG4

Shift Registers Overview

The SN74HC595DG4 is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It features a storage register with three-state outputs and operates within a supply voltage range of 2 V to 6 V. The device utilizes CMOS technology and is housed in a 16-pin SOIC package. Key electrical characteristics include a maximum propagation delay of 34 ns at 5 V and low input current of 1 µA. It supports asynchronous reset and is designed for industrial temperature ranges from -40°C to +85°C.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion using an 8-bit shift register architecture.
• Features three-state parallel outputs capable of driving multiple LSTTL loads.
• Includes direct asynchronous clear functionality for the storage register.

Shift Registers Applications

• Industrial control systems requiring serial data expansion
• Consumer electronics utilizing LED display drivers
• General-purpose digital logic interface circuits

Shift Registers Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's current datasheet to confirm RoHS compliance status and exact package dimensions. Ensure the ordering information matches the required tape-and-reel or tube packaging options available for this specific part number variant. Cross-reference the active status with official distributor channels to avoid obsolete stock.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with three-state outputs is required for serial-to-parallel conversion. It is suitable for applications needing wide voltage operation between 2 V and 6 V. Consider the SOIC-16 package constraints and the -40°C to +85°C operating temperature range during PCB layout and thermal design phases.

Shift Registers Part Context

This part belongs to the SNx4HC595 family of high-speed CMOS logic devices. It shares functional compatibility with other variants in the series, differing primarily in packaging and environmental ratings. The device is part of Texas Instruments' extensive portfolio of standard logic ICs designed for general-purpose digital applications.

Shift Registers Replacement Considerations

SN74HC595D is a non-RoHS compliant predecessor. SN74HC595DR offers the same function in a SOIC-16 package but may differ in reel specifications. Verify pinout compatibility before substitution.
