Function
Analog Ground.
One of two complementary outputs for Channel A. QA is 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 compare mode). See the description of Pin LEA for more information.

Analog Ground.
One of two complementary inputs for Channel A Latch Enable. In compare mode (logic high),
the output tracks changes at the input of the comparator. In latch mode (logic low), the output
reflects the input state just prior to the comparator being placed in the latch mode. LEA must
be driven in conjunction with LEA. If left unconnected, the comparator defaults to compare
mode.

the output tracks changes at the input of the comparator. In latch mode (logic high), the
output reflects the input state just prior to the comparator being placed in the latch mode. LEA

Negative Supply Terminal.
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.
Programmable Hysteresis Input.
Programmable Hysteresis Input.
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.
Positive Supply Terminal.
One of two complementary inputs for Channel B Latch Enable. In compare mode (logic low),
the output tracks changes at the input of the comparator. In latch mode (logic high), the
output reflects the input state just prior to the comparator being placed in the latch mode. LEB
must be driven in conjunction with LEB. If left unconnected, the comparator defaults to
compare mode.
