Receiver output: If A - B ≥ -50mV, RO is high; If A - B ≤ -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted.
Receiver output enable. RO is enabled when RE/RE is high / low; RO is high impedance when RE/RE is low/high. If the Rx enable
function isn’t used, connect RE directly to GND, or connect RE through a 1kΩ, or greater, resistor to V
low/high.
Ground connection. This is also the potential of the TDFN thermal pad.
