74LVC2G240 Dual Inverting Buffer/line Driver; 3-state

The 74LVC2G240 is a dual inverting Buffer Line Driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH level at pins nOE causes outputs to assume a high-impedance OFF-state. Schmitt Trigger action at all inputs makes the circuit highly tolerant of slower input rise and fall times. Inputs CAN be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in a mixed 3.3 V and 5 V environment. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
