4-Bit Binary Full Adder

The TC74AC283 is an advanced high speed CMOS 4-BIT

BINARY FULL ADDER fabricated with silicon gate and

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

Sum (Σ) outputs are provided for each bit and a resultant carry

(C4) is obtained from the fourth bit.

This adder features full internal look-ahead across all four bits.

A4 × n bit binary adder is easily built up by cascading the

AC283 without any additional logic.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
