CAPACITANCE OVER RECOMMENDED RANGES OF SUPPLY VOLTAGE AND OPERATING
FREE-AIR TEMPERATURE, f = 1MHz*
* Capacitance measurements are made on a sample basis only.
** Typical values are at T
SWITCHING CHARACTERISTICS OVER RECOMMENDED RANGES OF SUPPLY VOLTAGE
AND OPERATING FREE-AIR TEMPERATURE
NOTES:
1.Timing measurements are made at 2V for logic high and 0.8V for logic low (see figure 2).
2. Common test conditions apply for t
3. Value calculated from 0.5V delta to measured output level. This parameter is only sampled and not 100% tested.
