Pin No. Mnemonic Description
1 RO Receiver Output. When enabled, if A > B by 200 mV, RO = high. If A < B by 200 mV, RO = 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 V
CC
Power Supply, 5 V ±5%.
