Electrical Parameters
4) _{An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error}
current adds to the respective pin’s leakage current (I_OZ). The amount of error current depends on the overload
current and is defined by the overload coupling factor K_OV. The polarity of the injected error current is inverse
compared to the polarity of the overload current that produces it.
The total current through a pin is |I_TOT| = |I_OZ| + (|I_OV| × K_OV). The additional error current may distort the input
voltage on analog inputs.
5) _{The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output}
current may lead to increased delays or reduced driving capability (C_L).

Parameter Interpretation
The parameters listed in the following partly represent the characteristics of the XC161
and partly its demands on the system. To aid in interpreting the parameters right, when
evaluating them for a design, they are marked in column “Symbol”:
CC (Controller Characteristics):
The logic of the XC161 will provide signals with the respective characteristics.
SR (System Requirement):
The external system must provide signals with the respective characteristics to the
XC161.
