The test for open-drain outputs is intended to guarantee switching of the output transistor.
Measurement of this response is referenced from the midpoint of the switching signal, V
point 0.2 V above V
occurred. Beyond this level, the effects of external circuitry and test environment are
pronounced and can greatly affect the resultant measurement.
