PAL20RS4MJS883B

Programmable Logic Device Pld Overview

The PAL20RS4MJS/883B is a high-reliability Programmable Logic Device (PLD) manufactured by Advanced Micro Devices. It utilizes a PAL-type architecture with 18 dedicated inputs and 4 registered outputs, housed in a ceramic dual in-line package (CDIP-20). The device operates on TTL logic levels and features a maximum propagation delay of 45 ns. Designed for harsh environments, it supports an extended industrial temperature range from -55°C to +125°C. This component is part of the MIL-STD-883 qualified series, ensuring suitability for aerospace and defense applications requiring robust performance and long-term stability.

Programmable Logic Device Pld Part Context

This component belongs to the AMD PAL family of programmable logic devices. The '/883B' suffix indicates compliance with MIL-STD-883 standards for microelectronics, specifically denoting Class H or K space-level quality. It is distinct from commercial variants by its rigorous screening and radiation hardening capabilities inherent to the military specification packaging.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements must match the CDIP-20 footprint and PAL architecture. Verify that substitute parts maintain the 45 ns speed grade and TTL input thresholds. Ensure any alternative also holds the necessary /883B military qualification if the application requires it.
