3. Outputs loaded with external RL = 33W series resistor and CL = 15 pF to GND. Duty cycle out = duty in. A 0.01 mF decoupling capacitor
should be connected between VDD and GND. A 33 W series terminating resistor may be used on each clock output if the trace is longer than
1 inch.
4. Measured with railtorail input clock.
5. Measured on rising edges at VDD ÷ 2.
