4) Input thresholds are measured directly between the input pin and the tab. Any parasitic resistance in common between the load
current path and the input signal path can significantly affect the thresholds.
5) Rds(on) is measured between the Tab and the Out pin, 5mm away from the package.
Parameter
Turn-on delay time to Vcc-Vout= 0.9 Vcc
Rise time to Vcc-Vout=5V
Rise time to Vcc -Vout = 0.1Vcc
Turn ON energy
Turn-off delay to Vcc -Vout = 0.1Vcc
Fall time to Vcc-Vout = 0.9 Vcc
