description

The SN74AHC245Q octal bus transceiver is

designed for asynchronous two-way

communication between data buses. The

control-function implementation minimizes

external timing requirements.

This device 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.
