RO (Pin 1):
Receiver Output. If the receiver output is
enabled (RE LOW) and A > B by 200mV, then RO will be
HIGH. If A < B by 200mV, then RO will be LOW.
RE (Pin 2):
Receiver Output Enable. A LOW enables the
receiver output, RO. A HIGH input forces the receiver
output into a high impedance state.
DE (Pin 3):
Driver Outputs Enable. A HIGH on DE enables
the driver output. A, 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. If RE is high and DE is LOW, the part will enter a
low power (1
μ
A) shutdown state. If RE is low and DE is
high, the driver outputs will be fed back to the receiver and
the receive output will correspond to the driver input.
DI (Pin 4):
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.
GND (Pin 5):
Ground.
A (Pin 6):
Driver Output/Receiver Input.
B (Pin 7):
Driver Output/Receiver Input.
