Function
Analog Ground
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.
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.

Positive Supply Terminal
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.
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.
Analog Ground
Analog Ground
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.

No Connect. Leave pin unconnected.
Digital Ground
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.
