4-bit Binary Full Adder

REJ03D0607–0200

(Previous ADE-205-485)

Rev.2.00

Jan 31, 2006

Description

The sun (Σ) outputs are provided for each bit and the resultant carry (C4) is obtained from the fourth bit. This adder

features full internal look ahead across all four bits. This provides the system designer with partial look-ahead

performance at the economy and reduced package count of a ripple-carry implementation. The adder logic, including

the carry, is implemented in its true for meaning that the end-around carry can be accomplished without the need for

logic or level inversion.

Features

• High Speed Operation: tpd = 19 ns typ (CL = 50 pF)

• High Output Current: Fanout of 10 LSTTL Loads

• Wide Operating Voltage: VCC = 2 to 6 V

• Low Input Current: 1 µA max

• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)

• Ordering Information
