(Note 7) The tpLH propagation delay is measured from the 50% point on the trailing edge of the input pulse to the 1.3V point on the leading edge of the output pulse. The tpHL propagation delay is measured from the 50% point on the leading edge of the input pulse to the 1.3V point on the trailing edge of the output pulse. (Note 8) CML is the maximum rate of fall of the common mode voltage that can be sustained with the output voltage in the logic low state (VO > 0.8V). CMH is the maximum rate of rise of the common mode voltage that can be sustained with the output voltage in the logic state (VO > 2.0). (Note 9) A ceramic capacitor (0.1µF) should be connected from pin 8 to pin 5 to stabilize the operation of the high gain linear amplifier. Failure to provide the bypassing may impair the switching property. The total lead length between capacitor and coupler should not exceed 1cm.
