SN54AS32J

Overview

The SN54AS32J is a military-grade quadruple 2-input positive-OR gate manufactured by Texas Instruments. It belongs to the AS-TTL logic family and features a ceramic dual in-line package (DIP) with 20 pins. The device operates within a temperature range of -55°C to 125°C and requires a nominal 5V supply voltage. It provides push-pull outputs suitable for high-speed digital applications requiring robust performance under extreme environmental conditions.

Feature Summary

• Military-grade reliability certified for operation in harsh environments
• High-speed AS-TTL technology ensures rapid signal propagation
• Ceramic DIP packaging provides thermal stability and durability

Applications

• Aerospace avionics systems
• Military communication equipment
• Spacecraft digital logic circuits

Procurement Notes

Verify that the specific part number matches the required military grade specifications and ceramic package type. Confirm compliance with relevant defense standards and ensure the supplier provides appropriate traceability documentation for aerospace or military procurement requirements.

Selection Notes

Select this component when high-speed logic performance is required alongside strict military environmental tolerances. The AS-TTL family offers faster switching speeds compared to standard TTL variants, making it suitable for demanding real-time processing tasks in critical infrastructure.

Part Context

This component is part of the broader SN54 series of logic gates designed for military applications. It shares functional similarities with other OR gates in the ALS and LS families but distinguishes itself through superior speed characteristics inherent to the AS-TTL technology and ruggedized construction.

Replacement Considerations

Consider SN54LS32J as a potential substitute if higher speed is not critical. Verify pin compatibility and electrical parameter alignment before implementation.
