SURFACE MOUNT HCMOS CLOCK OSCILLATORS
FSO-2 SERIES
The FSO series is compatible with both TTL and HCMOS
technologies. The J-leaded configuration and high resistance to
soldering temperature make it ideal for surface mount production
processes. The FSO offers the low power consumption of HCMOS,
but will drive a full 10 TTL Gates when used in a TTL application.
This part is built to withstand vapor phase and other high temperature
soldering operations and to give long term outstanding performance
and reliability. Formechanically and electrically equivalent lower
cost alternative see page 50.

* Inclusive of 25C tolerance, operating temperature range, input voltage change, load change, aging, shock, and vibration.
*** An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
See page 35 for mechanical specifications, test circuits, and output waveform.
Note: ±50PPM frequency stability at -10 to +70°C also available (Up to 55 MHz)
Note: A 0.01F bypass capacitor should be placed between VDD (Pin 4) and GND (Pin 2) to minimize power supply line noise.
All specifications subject to change without notice.
