Description
Receiver Output. When RO is enabled, if (A − B) ≥ −30 mV, RO = high; if (A − B) ≤ −200 mV, RO = low.
Receiver Output Enable. A low level on this pin enables the receiver output, RO. A high level places RO
into a high impedance state.
Driver Output Enable. A high level on this pin enables the driver differential outputs, A and B. A low level
places them into a high impedance state.
Driver Input. When the driver is enabled, a logic low on DI forces A low and B high, whereas a logic high
on DI forces A high and B low.
Ground.

NOTES
1. THE EXPOSED PADDLE ON THE UNDERSIDE
OF THE PACKAGE SHOULD BE SOLDERED
TO THE GROUND PLANE TO INCREASE THE
RELIABILITY OF THE SOLDER JOINTS AND
TO MAXIMIZE THE THERMAL CAPABILITY OF
