functional description
The SN74GTLPH16945 is a medium-drive (50 mA), 16-bit bus transceiver partitioned as two 8-bit segments
and is designed for asynchronous communication between data buses. The device transmits data from the
A port to the B port or from the B port to the A port, depending on the logic level at the direction-control (DIR)
input. OE can be used to disable the device so the buses are effectively isolated. Data polarity is noninverting.
For A-to-B data flow, when OE is low and DIR is high, the B outputs take on the logic value of the A inputs. When
OE is high, the outputs are in the high-impedance state.
The data flow for B to A is similar to that of A to B, except OE and DIR are low.
