TC74AC245,640P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC245P, TC74AC245F, TC74AC245FT TC74AC640P, TC74AC640F, TC74AC640FT Octal Bus Transceiver TC74AC245P/F/FT 3-State, Non-Inverting TC74AC640P/F/FT 3-State, Inverting TC74AC245P, TC74AC640P The TC74AC245, 640 are advanced high speed CMOS OCTAL BUS TRANSCEIVERs fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. They are intended for two-way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. The enable input ( G ) can be used to disable the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge or transient excess voltage. TC74AC245F, TC74AC640F Features (Note 1)(Note 2) TC74AC245FT, TC74AC640FT High speed: tpd = 3.9 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 mA (min) Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 V to 5.5 V Pin and function compatible with 74F245/640 Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result. W...
