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

Description
1
RO
Receiver Output. When RO is enabled, if (A B) ≥ 30 mV, RO = high; if (A B) ≤ 200 mV, RO = low.
2
RE
Receiver Output Enable. A low level on this pin enables the receiver output, RO. A high level places RO
into a high impedance state.
3
DE
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.
4
DI
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.
5
GND
Ground.
6
A
Noninverting Receiver Input A/Noninverting Driver Output A.
7
B
Inverting Receiver Input B/Inverting Driver Output B.
8
VCC
5 V Power Supply.
