No Connect. Not internally connected, can be connected
to GND.
Half-/Full-Duplex Select Input. Connect H/F to V
half-duplex mode; connect H/F to GND or leave
unconnected for full-duplex mode.
Receiver Output. When RE is low and if (A - B) ≥ -50mV,
RO is high; if (A - B) ≤ -200mV, RO is low.
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 is a hot-swap
input (see the Hot-Swap Capability section for details).
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. DE is a hot-swap input (see the Hot-
Swap Capability section for details).
