具有三态输出的16位总线收发器 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS
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.
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.
