1. 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 than this.
VMAX specified 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.
