Preemphasis Enable Input. To enable preemphasis, leave PEE unconnected, connect to
V
CC
, or drive high. To enable strong-level-drive only mode, connect PEE to GND or drive
low.
PEE

Preemphasis Set Input. Sets the preemphasis interval. Connect a resistor (R
PSET
) in paral-
lel with a capacitor (C
PSET
) from PSET to V
CC
to set the preemphasis interval. See Typical
Operating Circuit

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

Driver Input. With DE high, a low on DI forces the noninverting output low and the inverting
output high. Similarly, a high on DI forces the noninverting output high and the inverting
output low.
