Mnemonic Description
ADCMP551 ADCMP552 ADCMP553
13 16 LEB
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 into latch mode. LEB must be driven in conjunction
with LEB.
15 18
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.
16 19 QB
One of Two Complementary Outputs for Channel B. QB 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 LEB for more information.
