DESCRIPTION
Receiver Output. When RE is low and
1
RO
Out if (A-B)  -50mV, RO is high.
If (A-B)  -200mV, RO is Low.
Receiver Output Enable (Hot Swap).
2
RE
In ^{When RE is low, RO is enabled. When RE is High,}
RO is high impedance. When RE is high and DE is
low, shutdown mode is enabled.
Driver Output Enable (Hot Swap).
3
DE
In ^{When DE is high, outputs are enabled. When DE is}
low, outputs are high impedance. When DE is low
and RE is high, shutdown mode is enabled.
Driver Input.
With DE high, a low level on DI forces non-Inverting

DI
In _{output low and inverting output high. Similarly, a}
high level on DI forces non-Inverting output high
and inverting output low.
