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 is low; RO is high impedance when RE is high.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is low.
Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.
Ground connection.
±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, non-inverting receiver input and noninverting driver output. Pin is an input
if DE = 0; pin is an output if DE = 1.
