1
Inclusive of 25C tolerance, operating temperature range, input voltage change, load change, aging,
shock, vibration, and Vc = 1.65V.
2
An internal pullup resistor from pin 2 to pin 6 allows active output if pin 2 is left open.
3
Available on an individual inquiry basis.
4
Custom specifications from 45.000 to 80.000 MHz available on an individual inquiry basis.
Note: A 0.01F bypass capacitor should be placed between Vdd (Pin 6) and GND (Pin 3) to
minimize power supply line noise.
Note: An alternate pin connection with E/D on pin #5 is available.
All specifications subject to change without notice.
