PAL20L2MJS883B

Programmable Logic Device Pld Overview

The PAL20L2MJS/883B is a military-grade Programmable Logic Device (PLD) manufactured by Advanced Micro Devices. It utilizes PAL-type architecture with TTL logic compatibility and features a propagation delay of 45 ns. The device is housed in a ceramic dual in-line package (CDIP-20), specifically designed for high-reliability applications. It provides 18 dedicated inputs and 2 outputs, configured as combinatorial output functions. The component operates within an extended temperature range from -55 °C to +125 °C and requires a 5 V supply voltage.

Programmable Logic Device Pld Feature Summary

• Military-grade reliability with /883B certification suffix
• PAL-type architecture with 18 dedicated inputs and 2 outputs
• 45 ns maximum propagation delay
• Extended industrial/military temperature range (-55 °C to +125 °C)
• Ceramic DIP-20 package construction

Programmable Logic Device Pld Applications

• High-reliability digital logic control systems
• Military aerospace embedded logic replacement
• Industrial automation interface circuits
• TTL-compatible combinatorial logic implementation

Programmable Logic Device Pld Procurement Notes

Verify the /883B suffix confirms MIL-STD-883 compliance during sourcing. Confirm the specific speed grade corresponds to the 45 ns parameter. Ensure the CDIP-20 ceramic package matches the target footprint requirements. Check for RoHS non-compliance status due to legacy manufacturing processes.

Programmable Logic Device Pld Selection Notes

Select this part when 18 inputs and 2 outputs are sufficient for the design. Choose over standard commercial variants if the -55 °C to +125 °C temperature range is mandatory. Verify that the 45 ns delay meets the system timing constraints. Ensure the circuit design supports TTL input levels and open-collector or totem-pole output configurations typical of this PAL family.

Programmable Logic Device Pld Part Context

This component belongs to the AMD PAL20 series of programmable logic devices. The /883B designation indicates it has been screened and tested according to MIL-STD-883 standards. It serves as a drop-in replacement for older military logic designs requiring fixed-function PAL capabilities with high thermal stability.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements may include other PAL20L2 variants with different speed grades or package options. Verify logical equivalence before substitution. Cross-reference with current AMD/LTM military PLD portfolios for modern equivalents if long-term availability is a concern.
