No Connection. Not internally connected. Connect N.C. to GND or leave it unconnected.
Receiver Output. If receiver is enabled and (A - B) ≥ -50mV, RO = high; if (A - B) ≥ -200mV, RO = 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.
Driver Output Enable. Drive DE high to enable the driver outputs. Drive DE low to put the outputs in
high impedance. Drive RE high and DE low to enter low-power shutdown mode.
Driver Input. Drive DI low to force the noninverting output low and the inverting output high. Drive DI
high to force the noninverting output high and the inverting output low.
