CDP1871AC - CMOS Keyboard Encoder

Download the CDP1871AC datasheet PDF. This datasheet also covers the CDP1871A variant, as both devices belong to the same cmos keyboard encoder family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Directly interfaces with COP1BOO-series microprocessors.
  • Low power dissipation.
  • 3-state outputs.
  • Scans and generates code for 53 key ASCII keyboard plus 32 HEX keys (SPST mechanical contact switches).
  • Shift, control, and alpha lock inputs.
  • RC-controlled debounce circuitry.
  • Single 4 to 10.5 V supply (COPIB71A); 4 to 6.5 V (COPIB71AC).
  • N-key lockout The RCA-CDP1871A is a keyboard encoder designed to directly interface betwe.
