Function

One of two complementary inputs for Channel B 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. LEB must

be driven in conjunction with LEB. If left unconnected, the comparator defaults to compare

mode.

Analog Ground.

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 Pin LEB for more information.
