SN74LS597NS

Shift Registers Overview

The SN74LS597NS is an 8-bit serial-in or parallel-in, serial-out shift register manufactured by Texas Instruments. It belongs to the LS (Low-Power Schottky) logic family and features a 3-state output capability. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 30 MHz. It utilizes a standard 16-pin DIP package for through-hole mounting.

Shift Registers Feature Summary

• Provides serial-to-parallel conversion with parallel load capability
• Features 3-state outputs for bus-driven applications
• Includes dedicated serial input and serial output pins

Shift Registers Applications

• Data acquisition systems requiring serial data expansion
• LED display matrix scanning circuits
• Industrial control systems utilizing bus architectures

Shift Registers Procurement Notes

Verify the specific suffix 'N' indicates the PDIP-16 package variant when sourcing. Confirm RoHS compliance status as it varies by manufacturing date code. Ensure the design accommodates the 5V logic level requirements typical of the LS series. Check for obsolescence notices from the manufacturer prior to finalizing procurement plans.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with 3-state outputs is required in a through-hole format. It is suitable for designs needing parallel loading capabilities alongside serial shifting functions. Consider the LS series propagation delays and power consumption characteristics relative to system timing constraints.

Shift Registers Part Context

This part is part of the Texas Instruments 74LS597 series, which integrates shift register functionality with 3-state buffers. It serves as a bridge between serial data sources and parallel processing units. The device is commonly used in legacy digital systems where space-efficient I/O expansion is necessary.
