Half/Full-Duplex Selector Pin. Connect H/F to V
duplex mode; connect to GND or leave unconnected for
full-duplex mode.
Receiver Output. When RE is low and if A - B ≥ -50mV,
RO will be high; if A - B ≤ -200mV, RO will be 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 driver out-
puts. These outputs are high impedance when DE is low.
Drive RE high and DE low to enter low-power shutdown
mode.
Driver Input. With DE high, a low on DI forces noninverting
output low and inverting output high. Similarly, a high on DI
forces non-inverting output high and inverting output low.
Slew-Rate-Limit Selector Pin. Connect SRL to GND for
10Mbps communication rate; connect to V
500kbps communication rate. Leave unconnected for
115kbps communication rate.
Ground
Transmitter Phase. Connect TXP to GND, or leave floating
for normal transmitter phase/polarity. Connect to V
invert the transmitter phase/polarity.
