Receiver output: If A > B by at least 0.2V, RO is high; If A < B by 0.2V or more, RO is low; RO = High if A and B are unconnected (floating).
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.
±15kV HBM ESD Protected, RS485, RS4-422 level noninverting receiver input and noninverting driver output. Pin is an input (A) if
DE = 0; pin is an output (Y) if DE = 1.
±15kV HBM ESD Protected, RS485, RS4-422 level inverting receiver input and inverting driver output. Pin is an input (B) if DE = 0;
