Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. If
the enable function isn’t needed, connect RE to GND. RE is internally pulled low.

Receiver output enable. RO is enabled when RE is high; RO is high impedance when RE is low. If
the enable function isn’t needed, connect RE to V_CC through a 1kΩ or greater resistor. RE is
internally pulled high.
