This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2/ If VSS is open circuited with VDD and GND applied, the VSS pin will be pulled positive, exceeding the Absolute Maximum Ratings. If this possibility exists, a Schottky diode from VSS to GND (cathode end to GND) ensures that the Absolute Maximum Ratings will be observed. 3/ Overvoltage at IN, S, or D will be clamped by diodes. Current should be limited to 20mA (see above). : Thermal Resistance, cerdip (Q) Package Junction-to-Case (JC) = 35°C/W Max Junction-to-Ambient (JA) = 120°C/W Max
