Note 1:
These parameters are characterized but not tested.
2:
Data in "Typ" column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
3:
Standby current is measured with all I/O in hi-impedance state and tied to VDD and VSS.
4:
For RC CLK, current through REXT is not included. The current through the resistor can be estimated by
the formula
Ir = VDD/2 REXT (mA) with REXT in kohm.
5:
Negative current is defined as coming out of the pin.
