FUNCTION
RO
1
2
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.
RE
2
3
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. Internally
pulled low.
DE
3
4
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.
DI
4
5
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.
GND

6, 7
Ground connection.

-
±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.
B/Z
7
-
±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.
