74HC283 ( 4 Bit Binary Adder) blower Noise suppression

Noise suppression

General Features:

The binary sum appears on the sum outputs (S1 to S4) and the out-going carry (COUT) according to the equation:

Single up/down control input

Pin 10: B3 – Input 2 (Gate 3)

74HC283 ( 4 Bit Binary Adder) blower Noise suppressionThe 74HC283 adds two 4 bit binary words (An plus Bn) plus the incoming carry (CIN). The binary sum appears on the sum outputs (S1 to S4) and the out going carry (COUT) according to the equation: CIN + (A1 + B1) + 2(A2 + B2) + 4(A3 + B3) + 8(A4 + B4) = S1 + 2S2 + 4S3 + 8S4 + 16COUT Where (+) = plus. Due to the symmetry of the binary add function, the 74HC283 can be used with either all active HIGH operands (positive logic) or all active LOW operands
