DESCRIPTION
The M74HC283 is an high speed CMOS 4 BIT BINARY FULL ADDER fabricated with silicon gate C2MOS technology.

■ HIGH SPEED : tPD = 17ns (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION: ICC =4µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 % VCC (MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
■ FULL-CARRY LOOK-AHEAD ACROSS THE FOUR BITS
■ PARTIAL LOOK-AHEAD WITH THE ECONOMY OF RIPPLE CARRY
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 283
