74LVC245APW

74LVC245APWThe 74LVC245A; 74LVCH245A is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V 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, preventingthe potentially damaging backflow current through the device when it is powered down.
