LEB

One of Two Complementary Inputs for Channel B Latch Enable. In the compare

mode (logic low), the output tracks changes at the input of the comparator. In

the latch mode (logic high), the output reflects the input state just prior to the

comparator’s being placed in the latch mode. LEB must be driven in conjunction

with LEB.

QB

One of Two Complementary Outputs for Channel B. QB is 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

description of Pin LEB for more information.
