4 / 35 page PCA9544A SCPS146E – OCTOBER 2005 – REVISED JUNE 2014 www.ti.com 7 Specifications 7.1 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC Supply voltage range –0.5 7 V VI Input voltage range(2) –0.5 7 V II Input current ±20 mA IO Output current ±25 mA Continuous current through VCC ±100 mA Continuous current through GND ±100 mA DGV package(3) 92 DW package(3) 58 GQN package(3) 78 θJA Package thermal impedance °C/W PW package(3) 83 RGW package(4) TBD RGY package(4) 37 Ptot Total power dissipation 400 mW TA Operating free-air temperature range –40 85 °C (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. 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. (4) The package thermal impedance is calculated in accordance with JESD 51-5. 7.2 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –60 150 °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. 7.3 Recommended Operating Conditions (1) MIN MAX UNIT VCC Supply voltage 2.3 5.5 V SCL, SDA 0.7 × VCC 6 VIH High-level input voltage V A2–A0, INT3–INT0 0.7 × VCC VCC + 0.5 SCL, SDA –0.5 0.3 × VCC VIL Low-level input voltage V A2–A0, INT3–INT0 –0.5 0.3 × VCC TA Operating free-air temperature –40 85 °C (1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
