diode. The comparators have two common signal inputs, PCA

signals. The self−bias circuit adjusts small voltage signals in the linear
region of the amplifier. Phase comparator 1 (an exclusive OR gate)

Features
Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
