Application Scenarios & Design Considerations

LOW-POWER HIGH-PERFORMANCE IMPACT E PAL CIRCUITS

Alternative Part Number

  • PAL20R4BCNT --: Same PAL20R4 family with 25 ns speed grade and 24-pin DIP package, functionally equivalent replacement.
  • PAL20R4ACNT --: Same PAL20R4 architecture in a 24-pin DIP; slightly different speed grade but pin-compatible and usable in most designs.
  • GAL20V8B-25LP --: Generic array logic device that can emulate the PAL20R4 function, 25 ns speed, 24-pin DIP, and widely available as a replacement.
