SCAS868 – DECEMBER 2008 THERMAL AIR FLOW (CFM) CDCV304PW 8-PIN TSSOP UNIT 0 150 250 500 RθJA High K 149 142 138 132 °C/W RθJA Low K 230 185 170 150 °C/W RθJC High K 65 °C/W RθJC High K 69 °C/W (1) The package thermal impedance is calculated in accordance with JESD 51 and JEDEC2S2P (high-k board). over operating free-air temperature range (unless otherwise noted) VALUE UNIT VDD Supply voltage range –0.5 to 4.6 V VIN Input voltage range –0.5 to 4.6 V Vout Output voltage range –0.5 to 4.6 V IIN Input current (VI < 0, VI > VDD) ±20 mA Iout Continuous output current ±50 mA TST Storage temperature range –65 to 150 °C TJ Maximum junction temperature 125 °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.
