TEST METHOD @ 25°C
1) Delay measured at 1.5V on leading edge only with no loads
on ouput.
2) Rise time measured from 0.75V to 2.4V.
3) Delay will inversely vary approximately 4% for every 5%
change in supply voltage.
4) Delay time and rise time measurements made with no loads
on tap.
5) Pulse period to be a minimum of 3x the pulse width.
