Output is guaranteed to be either low (VSEQ_DONEL = 0.4 V)

or giving a valid output level from VVCC = 1 V, ISINK = 30 μA

or VVCC = 1.1 V, ISINK = 100 μA

1 Input comparators do not include hysteresis on their inputs. The comparator output passes through a digital glitch filter to remove short transients from the input

signal that would otherwise drive the state machine.
