Latch Enable Pin. When ꢀꢁꢂꢃT is set HIGH, the output of the
comparator will toggle normally based on the inputs to the
comparator. For instance, when ꢀꢁꢂꢃT is set LOW and the
TS12011 output is HIGH, the output will remain HIGH despite
any changes to the input of the comparator. The output will once
again respond to changes to the input when ꢀꢁꢂꢃT is toggled
HIGH. If the output of the comparator is initially LOW and the
ꢀꢁꢂꢃT is then LOW, the output will stay LOW. If a LOW-to-
HIGH transition occurs on the output, the output will switch to
HIGH and stay HIGH and not respond to any changes at the
input. The ꢀꢁꢂꢃT pin must always be set to a known state. The
TS12012 output is the inverted version of the TS12011 output.
For unlatched comparator operation, set ꢀꢁꢂꢃT to HIGH.
