SN74LS597NSR

Shift Registers Overview

The SN74LS597NSR is an eight-bit serial-in or parallel-in, serial-out shift register manufactured by Texas Instruments. It belongs to the SN74LS series and features a three-state output. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum operating frequency of 20 MHz. It is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.3 inches. The component is RoHS compliant and lead-free.

Shift Registers Feature Summary

• Supports both serial input and parallel input data loading configurations
• Provides three-state outputs for bus-driven applications
• Includes a separate clock for the storage register to isolate data shifting from output presentation

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Parallel-to-serial data transmission interfaces
• General-purpose shift register functions in logic circuits

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required environmental standards such as RoHS compliance for the intended application. Cross-reference the datasheet revision date to confirm technical accuracy before integration into design projects.
