Programmable Logic Device Pld Part Context

This component is part of the AMD PAL16R8 family, which includes variants like PAL16L8, PAL16R6, and PAL16R4. The PAL16R8 series was designed to replace high-speed TTL logic gates, offering reprogrammability while maintaining speed comparable to standard logic families. The specific '-4' speed grade denotes a 4ns delay, making it one of the faster options in the 20-pin PAL lineup.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other manufacturers' PAL16R8 devices such as the Lattice GAL16V8 or Texas Instruments PAL16R8, provided the logic function is reprogrammed. Ensure the replacement supports the required 4ns speed grade and operates within the specified voltage and temperature ranges.
