Specifications

Supply voltage VDDH ....................VSS-0.5 to 4.5 V
VDDL, VDDLS,VDDP......................... VSS-0.5 to 3.5 V
Input voltage VIN........... VSS - 0.5 to VDDH + 0.5 V
Storage temperature TSTG............... - 55 to 125
Maximum dissipation (Ta = 70) PD................ 1 W
Note: The absolute maximum ratings are rated values which must not be exceeded during operation,even for an instant. Any one of the ratings must not be exceeded. If any absolute maximum rating is exceeded, a device may break down or its performance may be degraded, causing it to catch fire or explode resulting in injury to the user. Thus, when designing products which include this device, ensure that no absolute maximum rating value will ever be exceeded.
