TC74AC283P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC283P, TC74AC283F 4-Bit Binary Full Adder The TC74AC283 is an advanced high speed CMOS 4-BIT BINARY FULL ADDER fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Sum (Σ) outputs are provided for each bit and a resultant carry (C4) is obtained from the fourth bit. This adder Features full internal look-ahead across all four bits. A4 × n bit binary adder is easily built up by cascading the AC283 without any additional logic. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features - High speed: tpd = 7.0 ns (typ.) at VCC = 5 V - Low power dissipation: ICC = 8 μA (max) at Ta = 25°C - High noise immunity: VNIH = VNIL = 28% VCC (min) - Symmetrical output impedance: |IOH| = IOL = 24 m A (min) Capability of driving 50 Ω transmission lines. - Balanced propagation delays: tp LH ∼- tp HL - Wide operating voltage range: VCC (opr) = 2 to 5.5 V - Pin and function patible with 74F283 Pin Assignment TC74AC283P Weight DIP16-P-300-2.54A SOP16-P-300-1.27A : 1.00 g (typ.) : 0.18 g (typ.)
