Function
Logic Supply Terminal.
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 the compare mode). See the
description of Pin LEA for more information.

description of Pin LEA for more information.
One of Two Complementary Outputs for Channel A Latch Enable. In the
compare mode (logic high), the output tracks changes at the input of the
comparator. In the latch mode (logic low), the output reflects the input state just
prior to the comparator’s being placed in the latch mode. LEA must be driven in
conjunction with LEA.

comparator. In the latch mode (logic low), the output reflects the input state just

Input 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.
Programmable Hysteresis.
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.
