SN74LS323DWR

Shift Registers Overview

The SN74LS323DWR is an 8-bit universal shift/storage register from Texas Instruments, part of the 74LS series. It features a 20-SOIC package and operates within a voltage range of 4.75 V to 5.25 V. The device supports serial-in/serial-out, serial-in/parallel-out, parallel-in/serial-out, and parallel-in/parallel-out configurations. It includes dedicated inputs for serial data, clock control, and parallel load functionality, enabling versatile data handling in digital logic applications.

Shift Registers Feature Summary

• Supports multiple data transfer modes including serial and parallel I/O configurations
• Provides independent clock controls for serial and parallel operations
• Features asynchronous master reset capability for immediate initialization

Shift Registers Applications

• Digital data storage and buffering systems
• Serial-to-parallel and parallel-to-serial conversion circuits
• Shift register chains for extended bit manipulation

Shift Registers Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance with certain directives. Confirm humidity sensitivity level (MSL 3) requirements for surface mount assembly processes. Ensure operating temperature range (0°C to +70°C) aligns with target environment specifications before procurement.

Shift Registers Selection Notes

Select this component when 8-bit universal shift/register functionality is required in standard TTL-compatible logic families. Consider the 20-pin SOIC package for PCB layout constraints. Verify power supply stability within the specified 4.75V to 5.25V range to ensure reliable operation across all supported modes.

Shift Registers Part Context

This part belongs to the Texas Instruments 74LS series of logic integrated circuits, designed for general-purpose digital applications. It complements other 74LS components like gates and flip-flops by providing essential data movement and storage capabilities within larger digital systems.

Shift Registers Replacement Considerations

Check for compatible equivalents such as SN74LS323N or other 74LS323 variants from different manufacturers. Ensure pin compatibility and electrical characteristics match before substitution.
