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 -30°C are guaranteed by design and are not production tested.)
