ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause permanent damage and
may degrade the lifetime and safety for both device and system using the device in the field. The functional operation at or
over these absolute maximum ratings is not assured.
■ MECHANICAL SPECIFICATIONS
Package size is designed 3.0 x 3.0 x 1.08 (mm
