Pin Description
Preemphasis Enable Input. To enable preemphasis, leave PEE unconnected, connect to
VCC, 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 (RPSET) in paral-
lel with a capacitor (CPSET) from PSET to VCC to set the preemphasis interval. See Typical
Operating Circuit.
PSET

Receiver Output Enable. Drive RE low to enable RO; RO is high impedance when RE is
high. Drive RE high and DE low to enter low-power shutdown mode.
RE

Receiver Output. When RE is low and if A - B
≥ 200mV, RO is high; if A - B ≤ -200mV, RO
is low.
RO
2
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.

Driver Output Enable. Drive DE high to enable the driver outputs. These outputs are high
impedance when DE is low. Drive RE high and DE low to enter low-power shutdown mode.
