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) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. (3) The package thermal impedance is calculated in accordance with JESD 51-7. 6.2 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –65 150 °C Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all 0 2000 pins(1) V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification 0 1000 JESD22-C101, all pins(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions MIN MAX UNIT VCC Supply voltage 2.3 5.5 V SCL, SDA 0.7 × VCC 5.5 VIH High-level input voltage V A2–A0, P07–P00, P17–P10 0.7 × VCC 5.5 SCL, SDA –0.5 0.3 × VCC VIL Low-level input voltage V A2–A0, P07–P00, P17–P10 –0.5 0.3 × VCC IOH High-level output current P07–P00, P17–P10 –10 mA IOL Low-level output current P07–P00, P17–P10 25 mA TA Operating free-air temperature –40 85 °C Copyright © 2005–2014, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: PCA9555 |
