1 2 2 RO
Receiver Output. If A > B by 200mV, RO will be high; if A < B by
200mV, RO will be low.
2 — 3 RE
Receiver Output Enable. RO is enabled when RE is low; RO is high
impedance when RE is high. If RE is high and DE is low, the device
will enter a low-power shutdown mode.
3 — 4 DE
Driver Output Enable. The driver outputs are enabled by bringing DE
high. They are high impedance when DE is low. If RE is high and DE
is low, the device will enter a low-power shutdown mode. If the driver
outputs are enabled, the parts function as line drivers. While they are
high impedance, they function as line receivers if RE is low.
4 3 5 DI
Driver Input. A low on DI forces output Y low and output Z high.
Similarly, a high on DI forces output Y high and output Z low.
