0.2VCC+0.9

0.2VCC–0.1

NOTE:

AC inputs during testing are driven at VCC –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’.

TIMING

REFERENCE

POINTS

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.
