5962-8515504RA

Overview

The Texas Instruments 5962-8515504RA is a high-performance Impact Programmable Array Logic (PAL) circuit housed in a 20-pin Ceramic Dual In-Line Package (CDIP). It operates within a military temperature range of -55°C to +125°C and features a maximum propagation delay of 20ns. The device utilizes TTL logic levels and is part of the TIBPAL16R4-20M series, designed for robust digital signal processing applications requiring reliable performance under extreme environmental conditions.

Feature Summary

• High-speed programmable logic architecture with 20ns propagation delay
• Military-grade reliability across extended temperature ranges
• TTL-compatible input and output logic levels

Applications

• Harsh environment digital control systems
• Military aerospace signal processing
• Industrial automation logic interfaces

Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm the specific suffix matches the required military specification. Ensure storage conditions comply with moisture sensitivity levels for ceramic packages. Request batch traceability documentation prior to purchase to guarantee supply chain integrity and compliance with defense standards.

Selection Notes

Select this component when designing systems requiring deterministic timing and high reliability in extreme temperatures. Compare against standard commercial PALs if cost is a primary constraint and environmental exposure is limited. Ensure the CDIP package fits the available PCB footprint and thermal management strategy for the target application environment.

Part Context

This part belongs to the Texas Instruments Impact PAL family, known for field-programmable flexibility and high speed. It serves as a bridge between fixed logic gates and complex microprocessors, offering customizable logic functions without the overhead of software execution in critical real-time hardware control loops.

Replacement Considerations

Direct substitutes include other TI military-grade PALs from the same Impact series. Verify pin compatibility and logic function equivalence before swapping. Commercial equivalents lack the required temperature range and may not meet strict military qualification standards.
