TC74HCT652AP
TC74HCT652AP TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT652AP Octal Bus Transceiver/Register (3-state) The TC74HCT652A is high speed CMOS OCTAL BUS TRANSCEIVER/REGISTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Its inputs are compatible with TTL, NMOS, and CMOS output voltage levels. This device is bus transceiver with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the internal registers. ALL inputs are equipped with protection circuits against static discharge or transient excess voltage. Weight: 1.50 g (typ.) Features (Note 1) (Note 2) • High speed: fmax = 60 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • Compatible with TTL output: VIH = 2.0 V (min) • Output drive capability: 15 LSTTL loads • • Symmetrical output impedance: |IOH| = IOL = 6 mA (min) Balanced propagation delays: tpLH ∼ tpHL − • Pin and function compatible with 74LS652 VIL = 0.8 V (max) Note 1: Do not apply a signal to any bus terminal when it is in the out put mode. Damage may result. Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down resistors. Pin Assignment 1 2007-10-01
