Electrical Characteristics (continued)

(Limits are 100% tested at TA = +25ºC and TA = +85ºC. Limits over the operating temperature range and relevant supply voltage

range are guaranteed by design and characterization. Specifications marked GBD are guaranteed by design and not production tested.

Specifications to the minimum operating temperature are guaranteed by design and are not production tested.)
