74HC283 ( 4 Bit Binary Adder) blower Number of Pins: 40

Number of Pins:      40

radio recorders

Single up/down control input

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

These heavy duty yet economical V bearing components are quiet and ideal in long length applications and can operate in harsh conditions

74HC283 ( 4 Bit Binary Adder) blower Number of Pins: 40The 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
