Test Points

AC inputs during testing are driven with

VIHmin for a logic 1 and VILmax for a logic 0.

Timing measurements are made at

VOHmin for a logic 1 and VOLmax for a logic 0.

Input and Output Low/High max./min. voltages are defined at Page 60.

Test Points

DD / 2

AC inputs during testing are driven with

VIHmin for a logic 1 and VILmax for a logic 0.

Timing measurements are made at

VDD/2 for a logic 1 and for a logic 0.

Input Low/High max./min. voltages are defined at Page 61 and Page 68.

Reference

Points

Load - 0.1 V

OL - 0.1 V

For timing purposes a port pin is no longer floating when a 100 mV change from load

voltage occurs, but begins to float when a 100 mV change from the loaded

VOH/VOL

level occurs (

IOH/IOL = 15 mA).
