1. Short-circuits can cause excessive heating and destructive dissipation.
2. Rth are typical values.
3. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
4. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins
of the device with no external series resistor (internal resistor < 5Ω). Done for all couples of pin
combinations with other pins floating.
5. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.

Package information
In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a lead-free second level interconnect . The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
