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 non inverting driver
output. Pin is an input if DE = 0; pin is an output if DE = 1.
±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, inverting receiver input and inverting driver output. Pin is
an input if DE = 0; pin is an output if DE = 1.
