Turn-On Delay
Turn-Off Delay
Negative current is defi ned as coming out of (sourcing) the specifi ed device terminal.
All unused inputs must be connected to ground. Pull-down resistors (approximately 10 kΩ) are recommended for inputs that are al-
All inputs simultaneously.
Turn-off delay is infl uenced by load conditions. Systems applications well below the specifi ed output loading may require timing con-
