10 / 23 page www.ti.com Absolute Maximum Ratings (1) Recommended Operating Conditions (1) PCA9548A 8-CHANNEL I2C SWITCH WITH RESET SCPS143B – OCTOBER 2006 – REVISED MARCH 2007 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 ICC Supply current ±100 mA DB package 63 DGV package 86 θ JA Package thermal impedance, junction to free air(3) DW package 46 °C/W PW package 88 RGE package 45 θ JP Package thermal impedance, junction to pad RGE package 1.5 °C/W Tstg Storage temperature range –65 150 °C 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. MIN MAX UNIT VCC Supply voltage 2.3 5.5 V SCL, SDA 0.7 × V CC 6 VIH High-level input voltage V A2–A0, RESET 0.7 × V CC VCC + 0.5 SCL, SDA –0.5 0.3 × V CC VIL Low-level input voltage V A2–A0, RESET –0.5 0.3 × V CC TA Operating free-air temperature –40 85 °C (1) All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. 10 Submit Documentation Feedback |
