SN74LS597DR

Shift Registers Overview

The SN74LS597DR is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the LS (Low-power Schottky) logic family and operates within a supply voltage range of 4.75 V to 5.25 V. The device features a propagation delay of 60 ns and supports a maximum operating frequency of 20 MHz. It is housed in a 16-pin SOIC package with an operating temperature range from 0°C to +70°C.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion for digital systems
• Features low-power Schottky logic for reduced power consumption
• Includes dedicated clock and clear inputs for precise control

Shift Registers Applications

• Data acquisition systems requiring serial input buffering
• Parallel output expansion for microcontroller interfaces
• Digital signal processing applications needing data storage

Shift Registers Procurement Notes

Verify the specific suffix 'DR' indicates the SOIC-16 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component matches the required logic family specifications for your circuit design before procurement.

Shift Registers Selection Notes

Select this component when serial-to-parallel conversion is required in space-constrained designs. The SOIC-16 package offers a compact footprint suitable for surface-mount technology. Verify that the 20 MHz frequency limit meets your system's timing requirements.

Shift Registers Part Context

This part is part of the SN74LS597 series, which includes variants like SN74LS597N in DIP packages. The 'DR' suffix specifically denotes the tape-and-reel packaging format for automated assembly. It serves as a functional equivalent to other 8-bit shift registers within the standard TTL logic ecosystem.
