AC Electrical Characteristics
VDD = 3.3 V ±10%, Ambient Temperature -40 to +85 ° C, unless stated otherwise
VDD = 5 V ±10%, Ambient Temperature -40 to +85 ° C, unless stated otherwise
Notes:
1. With rail to rail input clock.
2. Between any 2 outputs with equal loading.
3. Duty cycle on outputs will match incoming clock duty cycle. Consult IDT for tight duty cycle clock
generators.
4. With external series resistor of 33Ω positioned close to each output pin.
