NOTES: Turn-off delay is influenced by load conditions. Systems applications well below the specified output loading may require
timing considerations for some designs, i.e., multiplexed displays or when used in combination with sink drivers in a totem
pole configuration.
Positive (negative) current is defined as going into (coming out of) the specified device pin.
* Operation at a clock frequency greater than the specified minimum value is possible but not warranteed.
