Function
1
RO
Receiver Output. When enabled, if A is greater than B by 200 mV, RO is high. If A is less than B by 200 mV, RO is low.
2
RE
Receiver Output Enable. A low level enables the receiver output, RO. A high level places it in a high impedance state.
3
DE
Driver Output Enable. A high level enables the driver differential outputs, A and B. A low level places it in a high
impedance state.
4
DI
Driver Input. When the driver is enabled, a logic low on DI forces A low and B high, while a logic high on DI forces
A high and B low.
5
GND
Ground Connection, 0 V.
6
A
Noninverting Receiver Input A/Driver Output A.
7
B
Inverting Receiver Input B/Driver Output B.
8
VCC
Power Supply, 5 V ± 5%.
