74LVC2245A Octal transceiver with direction pin, 30 series termination resistors 5 V tolerant input/output 3-state Rev. 6 30 April 2021 Product data sheet 1. General description The 74LVC2245A is an 8-bit transceiver with 30 termination resistors and 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 I . The I circuitry OFF OFF disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2.
