These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal GND. (3) The MAX value VIN +0.3V applies for applicative operation (device switching), DC voltage applied to this pin may not exceed 4V 8.2 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –65 150 °C Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all 2000 pins(1) V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification 1000 JESD22-C101, all pins(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. The human body model is a 100-pF capacitor discharged through a 1.5-k Ω resistor into each pin. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 4 Submit Documentation Feedback Copyright © 2013–2014, Texas Instruments Incorporated |
