These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is guaranteed to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test

conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance

characteristics may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the

maximum Operating Ratings is not recommended.

(2)

When the input voltage (VI) at any pin exceeds the power supplies (VI < GND or VI > VDD), the current at that pin should be limited to 5

mA. Parasitic components and or ESD protection circuitry are shown in the figures in Table 2 for the LM95235's pins. Care should be

taken not to forward bias the parasitic diodes on pins 2 and 3. Doing so by more than 50 mV may corrupt the temperature

measurements. SNP refers to Snap-back device.

(3)

Human body model (HBM) is a charged 100 pF capacitor discharged into a 1.5 k

Ω resistor. Machine model (MM), is a charged 200 pF

capacitor discharged directly into each pin. Charged Device Model (CDM) simulates a pin slowly acquiring charge (such as from a

device sliding down the feeder in an automated assembler) then rapidly being discharged.
