Function
1
GND
Analog Ground
2
−INA
Inverting analog input of the differential input stage for Channel A. The inverting A input must be driven
in conjunction with the noninverting A input.
3
+INA
Noninverting analog input of the differential input stage for Channel A. The noninverting A input must
be driven in conjunction with the inverting A input.

6
+INB
Noninverting analog input of the differential input stage for Channel B. The noninverting B input must
be driven in conjunction with the inverting B input.
7
−INB
Inverting analog input of the differential input stage for Channel B. The inverting B input must be driven
in conjunction with the noninverting B input.
8
GND
Analog Ground
9
GND
Analog Ground
10
LEB
One of two complementary inputs for Channel B Latch Enable. In the compare mode (logic low), the
output will track changes at the input of the comparator. In the latch mode (logic high), the output will
reflect the input state just prior to the comparator’s being placed in the latch mode. LEB must be driven
in conjunction with LEB.
11
LEB
One of two complementary inputs for Channel B Latch Enable. In the compare mode (logic high), the
output will track changes at the input of the comparator. In the latch mode (logic low), the output will
reflect the input state just prior to the comparator’s being placed in the latch mode. LEB must be driven
in conjunction with LEB.
12
NC
No Connect. Leave pin unconnected.
13
GND
Digital Ground
14
QB
One of two complementary outputs for Channel B. QB will be at logic low if the analog voltage at the
noninverting input is greater than the analog voltage at the inverting input (provided the comparator is
in the compare mode). See the LEB description (Pin 11) for more information.
15
QB
One of two complementary outputs for Channel B. QB will be at logic high if the analog voltage at the
noninverting input is greater than the analog voltage at the inverting input (provided the comparator is
in the compare mode). See the LEB description (Pin 11) for more information.
