7. Electrical Specifications and Timings
7.1. Absolute Maximum Ratings
Operating Temperature ........................................................................................... 0 to 70
Storage Temperature .............................................................................................. -65 to 140
All Outputs and Supply Voltages, with respect to Ground ........................................ -0.5V to 7V
Power Dissipation ..................................................................................................
Warning:
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only.
Functionality at or above these limits is not recommended and extended exposure to "Absolute
Maximum Ratings" may affect device reliability.
