Note 2: All parameters are production tested at T
A
= +25°C and guaranteed by design over the specified temperature range.
Note 3: Signals on COM_, NO_, or NC_ exceeding V
CC
are clamped by internal diodes. Limit forward-diode current to maximum
current ratings.
Note 4: Guaranteed by design; not production tested.

Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
