RE  
Receiver Output. High when A > B by 200 mV; low when A < B by 200 mV.  
3
Receiver Output Enable. When RE is low, the receiver output RO is enabled. When RE is high, the  
output is high impedance. If RE is high and DE is low, the ADM3491 enters a shutdown state.

DE  
DI  
Driver Output Enable. A high level enables the driver differential outputs, Y and Z. A low level  
places the part in a high impedance state.  
Driver Input. When the driver is enabled, a logic low on DI forces Y low and Z high; a logic high  
on DI forces Y high and Z low.
