AC Electrical Characteristics
VDD = 2.5 V ±5%, Ambient Temperature -40 to +85° C, unless stated otherwise
VDD = 3.3 V ±5%, Ambient Temperature -40 to +85° C, unless stated otherwise
VDD = 5 V ±5%, 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.
