DESCRIPTION
Receiver Output. If the receiver output is enabled
(RE low), then if A > B by 200mV, RO will be
high. If A < B by 200mV, then RO will be low.
Receiver Output Enable. A low enables the
receiver output, RO. A high input forces the
receiver output into a high impedance state.
Driver Outputs Enable. A high on DE enables the
driver output. A and B, and the chip will function
as a line driver. A low input will force the driver
outputs into a high impedance state and the chip
will function as a line receiver.
Driver Input. If the driver outputs are enabled
(DE high), then a low on DI forces the outputs A
low and B high. A high on DI with the driver
outputs enabled will force A high and B low.
Ground Connection.
