Receiver Output. When
RE
is low and if A - B
≥
200mV, RO goes high; if A - B
≤
-200mV, RO goes low.

Half-/Full-Duplex Selector Input. Connect H/

to V
CC
for half-duplex mode, and
connect to GND for full-duplex mode.

Receiver Output Enable Input. Drive
RE
low to enable RO; RO is high impedance
when
RE
is high. For MAX1481 only, drive
RE
high and DE low to enter the low-
power shutdown mode.

3
Driver Output Enable Input. Drive DE high to enable driver outputs. These outputs
are high impedance when DE is low.
4
4
Driver Input. With DE high, a low on DI forces noninverting output low and invert-
ing output high. Similarly, a high on DI forces noninverting output high and invert-
ing output low.

*(MAX1485/MAX1486 only) In half-duplex mode, the driver outputs serve as receiver inputs. The full-duplex receiver inputs (A and B)
will still have a 1/8-unit load, but are not connected to the receiver.
