DESCRIPTION

The U74LVC2245A is an 8-bit transceiver with 30Ω

termination resistors and 3-state outputs. The device features

an output enable (OE) and transmit/receive (DIR) for direction

control. When the OE is high, the outputs will be in a

high-impedance OFF-state. Inputs can be driven from either

3.3V or 5V devices. This feature allows the use of these

devices as translators in mixed 3.3V and 5V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant

of slower input rise and fall times.

This device is fully specified for partial power down

applications using IOFF. The IOFF circuitry disables the output,

preventing the potentially damaging backflow current through

the device when it is powered down.

FEATURES

* Overvoltage tolerant inputs to 5.5V

* Wide supply voltage range from 1.2V to 3.6V

* CMOS low-power consumption

* IOFF circuitry provides partial Power-down mode operation

* Integrated 30 Ω termination resistors
