Receiver output. On the ISL31480E, or if
INV or RINV is low, then: If
A - B
≥ -10mV, RO is high; if A - B ≤ -200mV,
RO is low. If INV or RINV is high, then: If B - A
≥ -10mV, RO is high; if B - A ≤ -200mV, RO is
low. In all cases, RO = High if A and B are
unconnected (floating), or shorted together,
or connected to an undriven, terminated
bus (i.e., Rx is always failsafe open, shorted,
and idle, even if polarity is inverted).

Receiver output enable. RO is enabled
when RE is low; RO is high impedance
when RE is high. Internally pulled low.
DE

Driver output enable. The driver outputs, Y
and Z, are enabled by bringing DE high,
and they are high impedance when DE is
low. Internally pulled high (to VL on
ISL31480E and ISL31486E; to VCC on
other versions).
DI

Driver input. On the ISL31480E, or if INV or
DINV is low, a low on DI forces output Y
low and output Z high, while a high on DI
forces output Y high and output Z low. The
output states relative to DI invert if INV or
DINV is high.

±60V Fault Protected RS-485/RS-422
level I/O pin. On the ISL31480E, or if INV is
low, A/Y is the non-inverting receiver input
and non-inverting driver output. If INV is
high, A/Y is the inverting receiver input
and the inverting driver output. Pin is an
input if DE = 0; pin is an output if DE = 1.
