1 These maximum and minimum specifications are guaranteed over this range.
2 Temperature range: TMIN to TMAX: 40°C to +85°C at 50 MHz and 140 MHz, 0°C to 70°C at 240 MHz and 330 MHz.
3 Timing specifications are measured with input levels of 3.0 V (VIH) and 0 V (VIL) 0 for both 5 V and 3.3 V supplies.
4 Rise time was measured from the 10% to 90% point of zero to full-scale transition, fall time from the 90% to 10% point of a full-scale transition.
5 Measured from 50% point of full-scale transition to 2% of final value.
6 Guaranteed by characterization.
7 fCLK maximum specification production tested at 125 MHz; 5 V limits specified here are guaranteed by characterization.

NOTES
1. OUTPUT DELAY (
t6) MEASURED FROM THE 50% POINT OF THE RISING EDGE OF CLOCK TO THE 50% POINT
OF FULL-SCALE TRANSITION.
2. OUTPUT RISE/FALL TIME (
t7) MEASURED BETWEEN THE 10% AND 90% POINTS OF FULL-SCALE TRANSITION.
3. TRANSITION TIME (
t8) MEASURED FROM THE 50% POINT OF FULL-SCALE TRANSITION TO WITHIN 2% OF THE
FINAL OUTPUT VALUE.
