Pin Description
NAME
FUNCTION
1
A-
Inverting Receiver A Input
2
A+
Noninverting Receiver A Input
PIN
3
YA
Receiver A Output. Enabled when ENAC = high. YA will be logic high if A+ > A- by 200mV, and low if
A+ < A- by 200mV. It will be logic high if A+ and A- remain floating. Otherwise, the state is undetermined.
YA goes high impedance when ENAC = low.
4
ENAC
Receiver Output A and C Enable High. A logic high on this input enables receivers A and C.
8
GND
Ground
7
C-
Inverting Receiver C Input
6
C+
Noninverting Receiver C Input
5
YC
Receiver C Output. Same functionality as YA.
13
YB
Receiver B Output. Same functionality as YD.
12
ENBD
Receiver Output B and D Enable High. A logic high on this input enables receivers B and D.
11
YD
Receiver D Output. Enabled when ENBD = high. YD will be logic high if D+ > D- by 200mV, and low if
D+ < D- by 200mV. It will be a logic high if D+ and D- remain floating. Otherwise, the state is undetermined.
YD goes high impedance when ENBD = low.
10
D+
Noninverting Receiver D Input
9
