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.
