PAL20R8A-2MJS/883B

Programmable Logic Device Pld Overview

The PAL20R8A-2MJS/883B is a high-speed Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It features an OT PLD architecture with TTL input compatibility and a maximum propagation delay of 25 ns. The component utilizes a CDIP-20 ceramic dual in-line package, rated for operation between -55 °C and 125 °C. It provides 20 dedicated inputs and 8 registered outputs, supporting complex logic functions within a standard 20-pin footprint.

Programmable Logic Device Pld Feature Summary

• 25 ns maximum propagation delay for high-speed digital applications
• 20-pin Ceramic Dual In-Line Package (CDIP) suitable for military environments
• TTL-compatible inputs with registered output structure
• Extended industrial temperature range from -55 °C to 125 °C

Programmable Logic Device Pld Applications

• Military avionics logic control systems
• High-reliability industrial automation controllers
• Replacement for legacy TTL logic gates in defense equipment

Programmable Logic Device Pld Procurement Notes

Verify the authenticity of the /883B suffix, which indicates compliance with MIL-PRF-38534 standards. Confirm that the ceramic package integrity meets aerospace requirements. Check for RoHS non-compliance status due to the lead-based construction typical of this heritage part number.

Programmable Logic Device Pld Selection Notes

Select this component when a registered PAL architecture with 20 inputs and 8 outputs is required in a ruggedized ceramic package. Ensure the design supports TTL voltage levels. Consider the 25 ns delay against system timing constraints compared to faster CMOS alternatives.

Programmable Logic Device Pld Part Context

This part belongs to the AMD PAL20R8 family, designed as a direct pin-compatible replacement for standard 20-pin registered PAL devices. The /883B designation signifies screening according to military specifications, distinguishing it from commercial variants like the PAL20R8-2CNL.

Programmable Logic Device Pld Replacement Considerations

Direct functional replacements include other PAL20R8 series devices such as the PAL20R8-2CNL or PAL20R8-10CNL, provided the plastic package can be substituted for the ceramic version.
