SNJ54LS181J

Specialty Logic Overview

The SNJ54LS181J is a hermetically sealed ceramic dual-in-line package (CDIP) containing an LS series 4-bit arithmetic logic unit and function generator. It operates within a temperature range of -55°C to 125°C. The device features 24 pins, utilizes TTL-compatible inputs, and provides standard or inverted outputs for sixteen distinct functions.

Specialty Logic Feature Summary

• Provides sixteen selectable arithmetic and logic operations via mode select inputs
• Features independent carry propagation capabilities for multi-bit expansion
• Includes both true and complemented output terminals for each bit

Specialty Logic Applications

• High-reliability military computing systems
• Avionics data processing units
• Spacecraft telemetry control modules

Specialty Logic Procurement Notes

Verify the specific ordering suffix against current Texas Instruments documentation to confirm active production status and exact pinout configuration. Ensure procurement channels supply genuine components with traceable lot codes suitable for defense or aerospace qualification requirements.

Specialty Logic Selection Notes

Select this component when designing circuits requiring radiation-hardened or high-temperature tolerant arithmetic processing. Confirm that the system power budget accommodates the specified LS series current consumption and that the CDIP footprint matches the target printed circuit board layout.

Specialty Logic Part Context

This part belongs to the SN54LS181 family of arithmetic logic units manufactured by Texas Instruments. It shares functional specifications with commercial variants but differs in packaging and environmental ratings. The 'J' suffix denotes the hermetic ceramic construction required for extreme operating conditions.

Specialty Logic Replacement Considerations

SN54S181J serves as a compatible alternative within the same product family.
