Test Points

2.0 V

0.8 V

Note:

AC testing inputs are driven at 3.5 V for a logic “1” and 0.45 V for a logic

“0”. Timing measurements are made at 2.0 V for a logic “1” and 0.8 V for

a logic “0”.

Points

VOH – 0.15 V

VOL + 0.15 V

Note:

For timing purposes, a port pin is no longer floating when a 150 mV change from load

voltage occurs and begins to float when a 150 mV change from the loading VOH/VOL

level occurs with IOL/IOH ≤15 mA.
