PRELIMINARY
56-pin SSOP (300 mils)
Note 38
Measured from 0.4V to 2.0V
Measured from 2.0V to 0.4V
Measured on rising and falling edge at 1.25V
Assumes full supply voltage reached within
1 ms from power-up. Short cycles exist prior to
frequency stabilization.
Average value during switching transition. Used
for determining series termination value.
