Functional Description
The GTLP8T306 is an 8-bit transceiver providing the standard 245 functionality that supports both GTL and GTLP signal
levels.
Data polarity is non-inverting and the data flow direction is controlled by the T/R pin. The outputs are enabled to allow data
through the device when OE is LOW otherwise both the A and B ports are placed in a HIGH impedance state.
