DESCRIPTION
The M74HC283 is an high speed CMOS 4 BIT
BINARY FULL ADDER f abricated with silicon gate
C2MOS technology.
Sum (Σ) outputs are provided for each bit and a
resultant carry (C4) is obtained from the fourth bit.
This adder features full i nternal look ahead across
all four bits. A 4 x n binary adder is easily built up
by casc ading without any additional logic.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

CAPACITIVE CHARACT ERISTICS
1) C PD is defined as the value of the IC’s internal equivalent capacitance which is calculated f rom the operating current cons umption without
lo ad. (Ref er to Test Circ ui t ). Average operating current can be obta i ned by t he follow i ng e quation. ICC(opr) = CPD x VCC x fIN + ICC
