SN74HC595DE4

Shift Registers Overview

The SN74HC595DE4 is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It features a CMOS logic family with a wide operating voltage range of 2 V to 6 V and operates within a temperature range of -40°C to +85°C. The device includes a storage register with three-state outputs and separate clocks for the shift and storage registers. It utilizes a 16-pin SOIC package and supports asynchronous reset functionality.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities for microcontroller pin expansion
• Features independent clock inputs for shift and storage registers to control data timing separately
• Includes an asynchronous clear input to reset the shift register state immediately

Shift Registers Applications

• Microcontroller I/O port expansion in embedded systems
• Driving LED displays and indicator arrays
• Controlling relay modules and solenoid actuators

Shift Registers Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and manufacturing origin details as per Texas Instruments documentation. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the voltage supply remains within the specified 2 V to 6 V range during operation to maintain signal integrity and prevent device damage.

Shift Registers Selection Notes

Select this component when requiring a cost-effective solution for expanding digital output lines using minimal microcontroller pins. The HC series offers standard speed suitable for most general-purpose logic applications. Consider the SN74HCS595 if Schmitt trigger inputs are needed for noisy environments, or the SN74AHC595 for higher speed performance requirements.

Shift Registers Part Context

This part belongs to the SNx4HC595 family of 8-bit shift registers with three-state outputs. It is designed to replace older 74HC595 variants while maintaining pin compatibility. The device is widely used in industrial and consumer electronics for its reliability and ease of integration into serial communication protocols like SPI.
