All typical values are at VCC = 5 V, TA = 25°C.
For I/O ports, the parameters IIH and IIL include the off-state output current.
§ Not more than one output should be shorted at a time, and the duration of the short-circuit should not exceed one second. Set VO at 0.5 V to
avoid test equipment ground degradation.
