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 the LEA pin for more information.

the description of the LEA pin for more information.
Analog Ground.
One of Two Complementary Inputs for Channel A Latch Enable. In compare
mode (logic high), the output tracks change 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.

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.
