NOTE:
AC inputs during testing are driven at V_DD –0.5 for a logic ‘1’ and 0.45V for a logic ‘0’.
Timing measurements are made at the 50% point of transitions.

NOTE:
For timing purposes, a port is no longer floating when a 100mV change from load voltage occurs,
and begins to float when a 100mV change from the loaded V_OH/V_OL level occurs. I_OH/I_OL ≥ ±20mA.
