TC74AC02FT

TC74AC02P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC02P, TC74AC02F, TC74AC02FT Quad 2-Input NOR Gate The TC74AC02 is an advanced high speed CMOS 2-INPUT NOR GATE 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. The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: tpd = 3.7 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) Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 5.5 V Pin and function compatible with 74F02 TC74AC02P TC74AC02F TC74AC02FT Weight DIP14-P-300-2.54 SOP14-P-300-1.27A TSSOP14-P-0044-0.65A : 0.96 g (typ.) : 0.18 g (typ.) : 0.06 g (typ.)
