Typical values: Tamb = 25 °C; VCC = 5 V; IFon = 3 mA unless otherwise specified.
Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
