Testing Waveforms
TA = -40 °C to +125 °C; Frequency: max. 40 MHz;
Class A Pins: VDDP813 = 3.0 to 5.25 V; VSS = 0 V;

MCT04880
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.

MCT04881
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.

MCT05074
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).
