Description
1
VCC
5 V Power Supply.
2
RO
Receiver Output. When RO is enabled, if (A B) ≥ 30 mV, RO = high; if (A B) ≤ 200 mV, RO = low.
3
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.
4
GND
Ground.
5
Y
Noninverting Driver Output.
6
Z
Inverting Driver Output.
7
B
Inverting Receiver Input.
8
A
Noninverting Receiver Input.
