description/ordering informationThis 16-bit (dual-octal) noninverting bus
transceiver is operational at 0.8-V to 2.7-V VCC,
but is designed specifically for 1.65-V to 1.95-VCC operation.
The SN74AUC16245 is designed for
asynchronous communication between data
buses. The control-function implementation
minimizes external timing requirements.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission 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 that the buses are effectively isolated.
To ensure the 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 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.
