Programmable Logic Device Pld Part Context

This component belongs to the PAL22V10 series of Complex Programmable Logic Devices (CPLDs) originally developed by AMD. These devices were widely used in the 1980s and 1990s for replacing discrete logic gates. The '/B3A' suffix typically denotes specific packaging and temperature grade variations, such as ceramic dual in-line package (DIP) with extended industrial temperature ranges, though exact suffix definitions require reference to the specific datasheet revision.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements may be available from manufacturers like Lattice Semiconductor or Microchip Technology, which have acquired legacy PAL portfolios. When substituting, verify that the new device maintains the same 22-input/10-output configuration and 20 MHz speed grade. Ensure compatibility with existing programming tools if reprogramming is required.
