10. Static characteristics
[1]
Typical ratings are not guaranteed. The values listed are at room temperature and VDD = 3.3 V.
[2]
See Section 9 “Limiting values” for steady state (non-transient) limits on IOL or IOH.IfIOL /IOH exceeds the test condition, VOL /VOH may
exceed the related specication.
[3]
Pin capacitance is characterized but not tested.
Table 21.
Static characteristics
VDD = 3.0 V to 3.6 V; Tamb =0 °Cto+70 °C for industrial application; unless otherwise specied.
