Parameter
Characteristics
1. Power supply bypass is required and a 0.1uF in parallel with a 0.01uF high frequency capacitor is recommended.
2. Transition times are measured from 20% to 80% of a full 10K ECL level swing.

Supply Voltage (5 V or 3.3V 5%)
1. By setting pin 1 high, the outputs are disabled and output on pin
4 is held low while Complementary output on pin 5 is held high.
Output is enabled by setting pin 1 at < Vcc -1.6V.
