Description

This SN74AUC245 octal bus transceiver is operational at 0.8-V to 2.7-V VCC , but is designed specifically for 1.65-V to 1.95-V VCC operation.

The SN74AUC245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable ( OE ) input can be used to disable the device so the buses are effectively isolated.

To ensure the SN74AUC245 high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

This SN74AUC245 device is fully specified for partial-power-down applications using Ioff . The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
