SN74LS164DRE4

Shift Registers Overview

The SN74LS164DRE4 is an 8-bit parallel-out serial shift register from the Texas Instruments SN74LS164 series. It operates on a bipolar LS logic family with a supply voltage range of 4.75 V to 5.25 V. The device features a propagation delay of 32 ns and functions within a temperature range of 0°C to +70°C. It is housed in a 14-SOIC package.

Shift Registers Feature Summary

• Converts serial input data into parallel output via push-pull drivers
• Includes asynchronous reset functionality for immediate clearing
• Supports dual serial inputs for flexible clocking configurations

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Driving LED displays or indicator arrays
• Expanding I/O capabilities for microcontroller interfaces

Shift Registers Procurement Notes

Verify the component status as the base SN74LS164D model is listed as obsolete in some distributor records. Confirm RoHS compliance details, as the RE4 suffix typically indicates environmental compliance but requires validation against current manufacturer documentation. Ensure the SOIC-14 footprint matches your PCB design constraints before finalizing procurement.

Shift Registers Selection Notes

Select this component when low-power Schottky performance is required with standard TTL compatibility. The LS series offers faster switching than standard 74-series logic while consuming less power. Verify that the 5V operating voltage aligns with your system's power rails and that the SOIC-14 package is suitable for your assembly process.

Shift Registers Part Context

This part belongs to the widely used 74LS164 family of shift registers. It serves as a fundamental building block for converting serial data streams into parallel formats. The DRE4 suffix denotes specific packaging and environmental attributes within the broader SN74LS164 product line manufactured by Texas Instruments.

Shift Registers Replacement Considerations

SN74LS164DR is a direct pin-compatible alternative from the same manufacturer. Other manufacturers may offer equivalent parts under different naming conventions, but electrical characteristics must be verified for compatibility.
