NOTE:
AC INPUTS DURING TESTING ARE DRIVEN AT VDD–0.5 FOR A LOGIC ‘1’ AND
0.45V FOR A LOGIC ‘0’. TIMING MEASUREMENTS ARE MADE AT VIH MIN FOR A
LOGIC ‘1’ AND VIL 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 VOH/VOL LEVEL OCCURS. IOH/IOL > +
20mA.
