Buffers, Drivers, Receivers, Transceivers FAQ

What is the direction control mechanism?

The device uses a DIR pin to control the direction of data flow between port A and port B.

Is the device inverting or non-inverting?

The SN74LV245ANSR is a non-inverting transceiver, meaning the output data follows the input data polarity.
