Ordering number : ENA2203 LV52206XA Bi-CMOS IC LV52206XA Specifications Absolute Maximum Ratings at Ta = 25C Parameter Symbol Conditions Ratings Unit Maximum supply voltage V max V 5.5 V CC CC Maximum pin voltage1 V1 max SW 43 V Maximum pin voltage2 V2 max Other pin 5.5 V Allowable power dissipation Pd max Ta = 25C *1 1.30 W Operating temperature Topr 30 to +85 C Storage temperature Tstg 55 to +125 C *1 Mounted on a specified board: 70mm70mm1.2mm (4 layer glass epoxy) Caution 1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
