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. If the Rx enable function isn’t used,
connect RE directly to GND or through a 1kΩ to 3kΩ resistor to GND.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and are high impedance when DE is low. If the
Tx enable function isn’t used, connect DE to V
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.
±15kV HBM ESD Protected RS-485/422 level, noninverting receiver input and noninverting driver output. Pin is an input if DE = 0;
pin is an output if DE = 1.
±15kV HBM ESD Protected RS-485/422 level, Inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin is an
output if DE = 1.
