PAL16L8B-4ML/883B

Programmable Logic Device Pld Overview

The PAL16L8B-4ML/883B is a high-speed Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It belongs to the PAL16R8 family, featuring a TTL-compatible architecture with 16 inputs and 8 combinational outputs. The component operates within a military-grade temperature range of -55 °C to 125 °C and utilizes a ceramic dual in-line package (CDIP). With a maximum propagation delay of 4 ns, it serves as a direct replacement for standard TTL logic gates in high-performance digital systems.

Programmable Logic Device Pld Feature Summary

• Military-grade reliability with an operating temperature range of -55 °C to 125 °C
• High-speed performance with a maximum propagation delay of 4 ns
• Standard 20-pin CDIP package compatible with existing DIP footprints
• TTL-compatible logic levels for seamless integration into legacy designs

Programmable Logic Device Pld Applications

• Replacement for discrete high-speed TTL logic circuits
• Complex state machine implementations in industrial control systems
• Address decoding and bus arbitration in military-grade computing hardware
• Timing generation and pulse shaping in aerospace avionics

Programmable Logic Device Pld Procurement Notes

Verify the authenticity of the /883B suffix, which indicates screening to MIL-PRF-38534 standards. Confirm that the ceramic package matches the required environmental specifications for the target application. Ensure compatibility with existing programming equipment for PAL devices before procurement.

Programmable Logic Device Pld Selection Notes

Select this component when a 4 ns speed is required for a 16-input, 8-output combinatorial logic function. The PAL16L8B variant provides fixed OR gates suitable for pure combinational logic, unlike registered variants. Verify that the system voltage aligns with standard TTL requirements and that the thermal environment supports the specified military temperature range.

Programmable Logic Device Pld Part Context

This part is a member of the AMD PAL16R8 family, which includes the PAL16L8, PAL16R8, PAL16R6, and PAL16R4 architectures. The PAL16L8 series specifically offers the highest speed among 20-pin TTL PAL devices, making it ideal for applications requiring minimal logic delay without the overhead of registered outputs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include the PAL16L8B from other manufacturers such as Texas Instruments or National Semiconductor, provided they meet the 4 ns speed and military temperature grade requirements.
