5962-8515508RA

Overview

The Texas Instruments 5962-8515508RA is a military-grade programmable logic device (PLD) belonging to the PAL16R4 family. It features a fixed AND-plane and flexible OR-plane architecture, providing 16 input lines and 8 registered output lines with active-low tri-state control. The component operates within a wide temperature range of -55°C to +125°C, adhering to MIL-STD-883 standards for screening and reliability. It utilizes bipolar technology to ensure high-speed performance and low power consumption in demanding industrial and aerospace environments.

Feature Summary

• Military-grade construction compliant with MIL-STD-883 screening requirements
• Configurable logic array with 16 inputs and 8 registered outputs
• Wide operating temperature range suitable for extreme environmental conditions

Applications

• Aerospace avionics systems requiring radiation-hardened or screened logic components
• Industrial control systems operating under strict temperature constraints
• Defense electronics utilizing standard PAL architectures for state machine implementation

Procurement Notes

Verify that the supplier provides documentation confirming compliance with MIL-STD-883 testing procedures. Ensure the part number prefix matches the specific military screening level required by your design specifications. Request batch traceability certificates to validate the component's origin and handling history prior to integration into critical systems.

Selection Notes

Select this component when a registered PAL solution is required for complex decoding or state sequencing in harsh environments. Compare pin compatibility and logic density against modern CPLDs if redesign is feasible. Confirm that the bipolar technology characteristics align with the system's power budget and signal integrity requirements for high-speed switching applications.

Part Context

This part is a militarized version of the standard PAL16R4 programmable logic device. It belongs to the broader family of Texas Instruments PALs designed for high-reliability applications. The 5962 prefix indicates adherence to Department of Defense procurement standards, distinguishing it from commercial variants which lack rigorous environmental screening and long-term stability guarantees.

Replacement Considerations

Direct replacements include other manufacturers' PAL16R4 devices meeting MIL-STD-883 standards. Verify logical equivalence and timing parameters before substitution. Consider upgrading to field-programmable gate arrays if reprogrammability is required, though this may alter form factor and interface requirements.
