description/ordering information
The SN74AHC245 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 effectively are 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.
