REV P 051310

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 33

Ω positioned close to each output pin.
