PAL14L4ML883B

Programmable Logic Device Pld Overview

The PAL14L4ML883B is a high-performance Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It features a TTL-compatible interface with 14 dedicated inputs and 4 registered outputs, housed in a 20-pin ceramic DIP package. The component operates within an extended temperature range of -55°C to +125°C and requires a nominal 5V supply voltage. With a propagation delay of 45ns, it provides reliable combinatorial logic processing for demanding industrial and military applications.

Programmable Logic Device Pld Feature Summary

• TTL-compatible logic levels for direct interfacing with standard digital systems
• Extended industrial/military temperature rating from -55°C to +125°C
• 20-pin Ceramic Dual In-line Package (CDIP) for robust environmental sealing
• 45ns maximum propagation delay for high-speed logic switching

Programmable Logic Device Pld Applications

• Military avionics control systems requiring radiation-hardened or sealed packaging
• Industrial automation logic controllers operating in extreme temperatures
• Spacecraft telemetry and command decoding circuits
• High-reliability communication equipment interface logic

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'M' indicates the ceramic package variant distinct from plastic equivalents. Confirm MIL-STD-883 compliance status if required for defense contracts. Check for RoHS exemption documentation as legacy PLDs often lack modern environmental certifications. Ensure supply chain authenticity through authorized distributors due to potential obsolescence.

Programmable Logic Device Pld Selection Notes

Select this model when registered output functionality is required alongside TTL compatibility. Compare against PAL14L4MJ for plastic package alternatives if thermal constraints allow. Verify pinout compatibility with existing PCB footprints designed for CDIP-20 packages. Consider power consumption differences between registered and unregistered PAL variants for system-level thermal management.

Programmable Logic Device Pld Part Context

This part belongs to AMD's classic PAL family, widely used before FPGA adoption. The '883B' suffix typically denotes adherence to MIL-STD-883 testing standards. It serves as a drop-in replacement for older discrete logic designs in legacy systems. Availability may be limited to surplus or specialized semiconductor vendors.

Programmable Logic Device Pld Replacement Considers

Direct pin-to-pin replacements include PAL14L4MJ/883B for plastic package variants. Cross-reference with Lattice GAL16V8D for field-programmable alternatives if reprogramming capability is needed. Verify electrical characteristics match exactly before substituting in safety-critical circuits.
