1 Custom specifications from 45.000 to 80.000 MHz available on an individual inquiry basis.
2 An internal pullup resistor from pin 2 to pin 6 allows active output if pin 2 is left open.
3 Other temperature ranges, stabilities, and pullabilities available.
Note: A 0.01μF bypass capacitor should be placed between VDD (Pin 6) and GND (Pin 3) to
minimize power supply line noise.
All specifications subject to change without notice. Rev. 8/25/05
