Driver Input. With DE high, a low on DI forces noninverting
output low and inverting output high. Similarly, a high on DI
forces noninverting output high and inverting output low.

Slew-Rate-Limit Selector Pin. Connect SRL to GND for 10Mbps
communication rate; connect to VCC for 500kbps communication
rate. Leave unconnected for 115kbps communication rate.

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.

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.
