PI74LPT543

The PI74LPT543 is designed as one kind of fast CMOS 3.3V 8-bit latched transceiver device that can be driven from either 3.3V or 5.0V devices allowing PI74LPT543 to be used as a translator in a mixed 3.3 / 5.0V system. With xCEAB LOW, a LOW signal makes the A-to-B latches transparent; a subsequent LOW-to-HIGH transition of the xLEAB signal puts the A latches in the storage mode and their outputs no longer change the A inputs.

Features of the PI74LPT543 are:(1)Compatible with LCX and LVT families of products;(2)Advanced Low Power CMOS Operation;(3)Pin compatible with industry standard double-density pinouts;(4)Low ground bounce outputs;(5)Hysteresis on all inputs;(6)Industrial operating temperature range: 40°C to +85°C;(7)Multiple center pins and distributed Vcc/GND pins minimize switching noise.

The absolute maximum ratings of the PI74LPT543 can be summarized as:(1)Storage Temperature:55°C to +125°C;(2)Ambient Temperature with Power Applied:40°C to +85°C;(3)Supply Voltage to Ground Potential (Inputs & Vcc Only): -0.5 V to +7.0 V;(4)Supply Voltage to Ground Potential (Outputs & D/O Only): -0.5 V to +7.0 V;(5)DC Input Voltage: -0.5 V to +7.0 V;(6)DC Output Current: 120 mA;(7)Power Dissipation: 1.0 W.
