SNIS128C – AUGUST 2002 – REVISED MARCH 2013
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. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
When the input voltage (V I ) at any pin exceeds the power supplies (V I < GND or V I > V DD ), the current at that pin should be limited to 5
mA. Parasitic components and or ESD protection circuitry are shown in Table 1 and Figure 1 for the LM89's pins. The nominal
breakdown voltage of D3 is 6.5 V. Care should be taken not to forward bias the parasitic diode, D1, present on pins: D+, D ? . Doing so
by more than 50 mV may corrupt a temperature measurements.

Human body model, 100pF discharged through a 1.5k Ω resistor. Machine model, 200pF discharged directly into each pin.
