TEXAS INSTRUMENTS SN74ACT245PWR 收发器, 3态, 4.5 V至5.5 V, TSSOP-20
These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
When the output-enable OE\ is low, the device passes noninverted data from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control DIR input. A high on OE\ disables 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.
