CD74HCT283 - 4-Bit Binary Full Adder

Download the CD74HCT283 datasheet PDF. This datasheet also covers the CD74HC283 variant, as both devices belong to the same 4-bit binary full adder family and are provided as variant models within a single manufacturer datasheet.

Description

The CDx4HC283 and CDx4HCT283 contain 4-bit binary adders.

The HCT device has TTL-voltage compatible inputs.

Features

  • Adds two binary numbers.
  • Full internal lookahead.
  • Fast ripple carry for economical expansion.
  • Operates with both positive and negative logic.
  • Fanout (over temperature range).
  • Standard outputs 10 LSTTL loads.
  • Bus driver outputs 15 LSTTL loads.
  • Wide operating temperature range:.
  • 55℃ to 125℃.
  • Balanced propagation delay and transition times.
  • Significant power reduction compared to LSTTL Logic ICs.
