Note 1: Data in the Typical (“Typ”) column is based on characterization results at +25°C. This data is for design
guidance only and is not tested.
2: The leakage current on the RESET
pin is strongly dependent on the applied voltage level. The specified
levels represent normal operating conditions. Higher leakage current may be measured at different input
voltages.
3: Negative current is defined as coming out of the pin.
