SN74LVCR2245A 具有三态输出的八路总线收发器
This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCR2245A 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.
All outputs, which are designed to sink up to 12 mA, include equivalent 26-
resistors to reduce overshoot and undershoot.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
This device is fully specified for partial-power-down applications using Ioff
