4 / 30 page CDCE937-Q1 CDCEL937-Q1 SCAS892B – FEBRUARY 2010 – REVISED MAY 2010 www.ti.com ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT VDD Supply voltage range –0.5 to 2.5 V VI Input voltage range(2) (3) –0.5 to VDD + 0.5 V VO Output voltage range(2) –0.5 to Vddout + 0.5 V II Input current (VI < 0, VI > VDD) 20 mA IO Continuous output current 50 mA Tstg Storage temperature range –65 to 150 °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 and output negative voltage ratings may be exceeded if the input and output clamp-current ratings are observed. (3) SDA and SCL can go up to 3.6 V as stated in the Recommended Operating Conditions table.
