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.
Negative current is defined as coming out of (sourcing) the specified device terminal.
