HD74HC283
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)

Note: Input conditions at A1, B1, A2, B2, and C0 are used to determine outputs Σ1 and Σ2 and the value of the internal
carry C2. The values at C2, A3, B3, A4 and B4 are then used to determine outputs Σ3, Σ4 and C4.
