NOTE(S):
(1) _{The input test is done with 0.1 Vdd of overdrive (over Vih and Vil). Timing parameters must be met with no more overdrive}
than this. Production testing can use different voltage values, but must correlate results back to these parameters.
(2) _{Vmax specifies the maximum peak-to-peak voltage waveform allowed for measuring input timing. Production testing can use}
different voltage values, but must correlate results back to these parameters.
