Receiver output. If A-B ≥ -10mV, RO is high; if A-B ≤ -200mV, RO is low; RO = High if A and B are unconnected
(floating), shorted together, or connected to an undriven, terminated bus.
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. Internally pulled
low.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when
DE is low. Internally pulled high.
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.
±60V Fault and ±16.5kV HBM 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.
±60V Fault and ±16.5kV HBM 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.
±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level, non-inverting receiver input.
