Absolute Maximum Ratings(†)
VCC.............................................................................................................................................................................7.0V
All inputs and outputs w.r.t. VSS.........................................................................................................................................-0.6V to VCC +1.0V
Storage temperature ...............................................................................................................................-65°C to +150°C
Ambient temperature with power applied ................................................................................................-65°C to +125°C

† NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at those or any other conditions
above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
