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. This is also the potential of the TDFN EPAD.
±60V Fault 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 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 Protected RS-485/RS-422 level, non-inverting receiver input.
±60V Fault Protected RS-485/RS-422 level, inverting receiver input.
±60V Fault Protected RS-485/RS-422 level, non-inverting driver output.
±60V Fault Protected RS-485/RS-422 level, inverting driver output.
TDFN exposed thermal pad (EPAD). Connect to GND.
