Product Summary
The 74ACT245 is a octal bus transceiver. The 74ACT245 is 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 74ACT245 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.
