This 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-V 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.
