PAL20X4AML883B

Programmable Logic Device Pld Overview

The PAL20X4AML883B is a high-performance Programmable Logic Device (PLD) manufactured by Advanced Micro Devices (AMD). It belongs to the PAL20X4 family, featuring an OT PLD architecture with a propagation delay of 35ns. The device operates on TTL logic levels and supports a maximum clock frequency of 18 MHz. It is housed in a 20-pin CDFP ceramic flatpack package (CDFP20), measuring 0.250 x 0.500 inches. The component is qualified for military-grade operation, functioning reliably within a temperature range of -55°C to +125°C.

Programmable Logic Device Pld Feature Summary

• PAL20X4 Architecture: Features 20 dedicated inputs and 4 registered outputs with macrocell output logic.
• High Speed Performance: Delivers a typical propagation delay of 35ns, supporting system clock frequencies up to 18 MHz.
• Military-Grade Reliability: Certified for extended industrial and military environments with an operating temperature range from -55°C to +125°C.
• Ceramic Packaging: Utilizes a hermetically sealed 20-pin CDFP (Ceramic Dual Flatpack) package for enhanced durability.

Programmable Logic Device Pld Applications

• Military avionics systems requiring radiation-hardened or high-reliability logic control.
• Spacecraft guidance and navigation subsystems operating in extreme thermal conditions.
• Industrial automation controllers designed for harsh environmental deployments.
• High-speed digital state machine implementations in defense communication equipment.

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'AML883B' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the procurement source provides traceability documentation suitable for military or aerospace applications, as standard commercial variants may lack the required qualification standards.

Programmable Logic Device Pld Selection Notes

Select this component when a registered output PLD with 20 inputs is required for high-speed timing-critical applications. Compare the 35ns delay against faster alternatives if system throughput exceeds 18 MHz limits. Consider the CDFP package constraints during PCB layout, ensuring adequate clearance for the dual flatform footprint and thermal management for high-temperature operation.

Programmable Logic Device Pld Part Context

This part is part of AMD's legacy PAL20X4 series, widely used in retrofitted military electronics and legacy system maintenance. It serves as a direct replacement for older discrete logic gates in complex digital circuits. The '883B' designation indicates compliance with MIL-PRF-38534 standards for integrated circuits.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements include the PAL20X4AMJ/883B (DIP package) for form-factor adaptation if space permits. Verify logical equivalence with PAL20RA10 variants if registered outputs are not strictly required, noting differences in I/O configuration and speed characteristics.
