RO
Receiver Output. When enabled, if A > B by 200 mV, RO = high. If A < B by 200 mV, RO = low.
3
2
RE
Receiver Output Enable. A low level enables the receiver output, RO. A high level places the
ADM489A in a high impedance state.
4
3
DE
Driver Output Enable. A high level enables the driver differential outputs (Y and Z). A low level
places the ADM489A in a high impedance state.

DI
Driver Input. When the driver is enabled, a logic low on DI forces Y low and Z high, whereas a
logic high on DI forces Y high and Z low.
