Ob 1. AC inputs during testing are driven at VCC–0.5 V for a logic '1,' and 0.45 V for a logic '0.'
- 2. Timing measurements are made at VIH(min) for a logic '1,' and VIL(max) for a logic '0'

le1. For timing purposes, a Port pin is considered to be no longer floating when a 100mV change from load
o voltage occurs, and begins to float when a 100mV change from the loaded VOH or VOL level occurs
Obs 2. IOL and IOH ≥ 20 mA
