Description
Receiver Output. When enabled, if (A−B) ≥ −30 mV, then RO = high.
If (A−B) ≤ −200 mV, then RO = low.
Receiver Output Enable.
A low level enables the receiver output, RO.
A high level places it in a high impedance state.
Driver Output Enable. A high level enables the driver differential inputs A and B.
A low level places it in a high impedance state.
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.
Ground.
