Function

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

mode (logic low), the output tracks change 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.

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 compare mode). See

the description of the LEB pin for more information.
