Notes: The input test environment is done with 0.1 VDD of overdrive over VIH and VIL. Timing parameters must be met with no
more overdrive that this. VMAX specifies the maximum peak-to-peak waveform allowed for measuring input timing. Production
testing may use different voltage values, but must correlate results back to these parameters.
