Device Specifications

C501

AC Testing: Input, Output Waveforms

AC Testing: Float Waveforms

AC Inputs during testing are driven at V

– 0.5 V for a logic ‘1’ and 0.45 V for a logic ‘0’. Timing

measurements are made at

IHmin

for a logic ‘1’ and V

ILmax

for a logic ‘0’.

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

occurs and begins to float when a 100 mV change from the loaded

/ V

level occurs.

/ I

≥ ± 20 mA.
