TEXAS INSTRUMENTS SN74ALVC245PW 收发器, 非反相, 3态, 1.65V至3.6V, TSSOP-20
This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVC245 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 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.
