TC74HC283AP
TC74HC283AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC283AP,TC74HC283AF,TC74HC283AFN 4-Bit Binary Full Adder The TC74HC283A is a high speed CMOS 4-BIT BINARY FULL ADDER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL 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 HC283A without any additional logic. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxFN (JEDEC SOP) is not available in Japan. TC74HC283AP TC74HC283AF Features • High speed: tpd = 17 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 10 LSTTL loads • • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) ∼ Balanced propagation delays: tpLH − tpHL • Wide operating voltage range: VCC (opr) = 2 to 6 V • Pin and function compatible with 74LS283 TC74HC283AFN Pin Assignment Weight DIP16-P-300-2.54A SOP16-P-300-1.27A SOL16-P-150-1.27 1 : 1.00 g (typ.) : 0.18 g (typ.) : 0.13 g (typ.) 2007-10-01
