74HC4078AP
TC74HC4078AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4078AP,TC74HC4078AF 8-Input OR/NOR Gate The TC74HC4078A is a high speed CMOS 8-INPUT NOR GATE fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Output X is an 8-INPUT NOR, output Y is an 8-INPUT OR. Each output has a buffer, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features TC74HC4078AP TC74HC4078AF • High speed: tpd = 13 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 1 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 4078B Weight DIP14-P-300-2.54 SOP14-P-300-1.27A Pin Assignment : 0.96 g (typ.) : 0.18 g (typ.) NC: No connection IEC Logic Symbol 1 2007-10-01
