NOTE:
AC inputs during testing are driven at V_CC –0.5 for a logic ‘1’ and 0.45V for a logic ‘0’.
Timing measurements are made at V_IH min for a logic ‘1’ and V_IL max for a logic ‘0’.

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.
