Each channel 2. Measured between pins 1 through 8 shorted together and pins 9 through 16 shorted together. 3. Measured between pins 9 and 10 or 11 and 12 shorted together, and pins 9 through 16 shorted together. 4. Measured between pins 9 and 10 shorted together, and pins 11 and 12 shorted together. 5. The tplh 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 tphl 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. 7. CMh is the max. tolerable common mode transient to assure that the output will remain in a high logic state (i.e. VO > 2.0V). 8. CMl is the max. tolerable common mode transient to assure that the output will remain in a low logic state (i.e. VO < 0.8V). 9. It is essential that a bypass capacitor (.01 to 0.1F ceramic) be connected from pin 1 to pin 4.
