Not connected. Not internally connected.

2

RO

Receiver output. When RE is low and if A-B≥-50mV, RO will be high; if A-B≤ -500mV,

RO will be low.

3

RE

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.

4

DE

Driver output enable. Drive DE high to enable driver outputs. These outputs are high

impedance when DE is low. Drive RE high and DE low to enter low-power shutdown

mode.

5

DI

Driver input. With DE high, a low on DI forces non-inverting output low and inverting

output high. Similarly, a high on DI forces non-inverting output high and inverting output

low.
