The t plh propagation delay is measured from the 6.5mA point on the trailing edge of the input pulse to the 1.5V point on the trailing edge of the output pulse. 6. The t phl propagation delay is measured from the 6.5mA point on the leading edge of the input pulse to the 1.5V point on the leading edge of the output pulse. 9. It is essential that a bypass capacitor (.01 to 0.1 µF ceramic) be connected from pin 1 to pin 4.
