CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Signals on NC, NO, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to maximum current ratings.
3.
JA
is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

NOTES:
4. V
IN
= input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
7. Guaranteed but not tested.
8. R
ON
matching between channels is calculated by subtracting the channel with the highest max Ron value from the channel with lowest max Ron
value.
9. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
