Absolute Maximum Ratings (Note) Characteristics Symbol Rating Unit Supply voltage range VCC −0.5~7.0 V DC input voltage VIN −0.5~7.0 V DC output voltage VOUT −0.5~VCC + 0.5 V Input diode current IIK −20 mA Output diode current IOK ±20 mA DC output current IOUT ±25 mA DC VCC/ground current ICC ±75 mA Power dissipation PD 180 mW Storage temperature Tstg −65~150 °C Note: Exceeding any of the absolute maximum ratings, even br iefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
