programmable peripheral interfaceCMOS24 I/O5 VDIP-40

CLM82C55A-2R3 is a 5 V CMOS programmable peripheral interface providing 24 configurable I/O lines in a 40-pin DIP package.

Best for

  • Legacy 5 V microprocessor systems
  • Parallel peripheral interfaces
  • Printer, keyboard, display, and industrial control interfaces

Avoid if

  • The design requires a low-voltage interface below the specified 4.5 V to 5.5 V operating range
  • The application requires modern serial interfaces or higher output current

Check before use

  • Confirm the DIP-40 mechanical footprint and 2.54 mm pin pitch
  • Confirm handshake and interrupt pin allocation in Mode 1 or Mode 2
  • Confirm current datasheet and supply status
