Description
1
2
RO
Receiver Output. Type 1 receiver (ADN4690E/ADN4692E), when enabled: if A B ≥ 50 mV, then
RO = logic high. If A B ≤ 50 mV, then RO = logic low. Receiver output is undefined outside these
conditions.
2
3
RE
Receiver Output Enable. A logic low on this pin enables the receiver output, RO. A logic high on this
pin places RO in a high impedance state.
3
4
DE
Driver Output Enable. A logic high on this pin enables the A and B driver differential outputs.
A logic low on this pin places the A and B driver differential outputs in a high impedance state.
4
5
DI
Driver Input. Half-duplex (ADN4690E), when enabled: A logic low on this pin forces A low and B
high, whereas a logic high on this pin forces A high and B low.
Full-duplex (ADN4692E), when enabled: A logic low on this pin forces Y low and Z high, whereas
a logic high on this pin forces Y high and Z low.
