RO is high; if (A - B) ꢁ -200mV, RO is low.
RO
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-

Driver Output Enable. Drive DE high to enable driver

DE
Driver Input. With DE high, a low on DI forces noninverting
