Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. Duty cycle on outputs will match incoming clock duty cycle. Consult ICS for tight duty cycle clock generators.
3. With external series resistor of 33 Ω positioned close to each output pin.
