Pin Function
3.0V to 5.5V power supply input bypass to ground with 0.1μF capacitor.
Non inverting receiver input.
Inverting receiver input.
Non-inverting driver output.
Inverting driver output.
Driver invert control (active high). When enabled, the polarity of the driver input pin is
inverted causing the driver output (Y & Z) polarities to be inverted. When disabled, the
driver bus pins (Y & Z) operate normally: Y = non-inverting and Z = inverting. The D_INV
pin has a 150kΩ pull-down resistor.
Logic interface power supply.
