74LVC16245A 74LVCH16245A 16-bit bus transceiver with direction pin 5 V tolerant 3-state Rev. 14 24 September 2021 Product data sheet 1. General description The 74LVC16245A 74LVCH16245A is a 16-bit transceiver with 3-state outputs. The device can be used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables (1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for direction control. A HIGH on nOE 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. The 74LVCH16245A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 2.
