Pin Function Descriptions 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 VCC Power Supply, 5 V ±5%.
