Description
Receiver Output. When enabled, if A > B by 200 mV, then RO = high. If A < B by 200 mV, then RO = low.
Receiver Output Enable. A low level enables the RO; a high level places it in a high impedance state.
Driver Output Enable. A high level enables the driver differential outputs, Pin A and Pin B; a low level places
the driver in a high impedance state.
Driver Input. When the driver is enabled, a logic low on DI forces Pin A low and Pin B high; a logic high on DI
forces Pin A high and Pin B low.
Ground Connection (0 V).
Noninverting Receiver Input A/Driver Output A.
Inverting Receiver Input B/Driver Output B.
Power Supply (5 V ± 10%).
