PROCESS RECOMMENDATIONS  
Solder Reflow  
TABLE 6.0  
The component solder used internal to this device has a m elting point of  
221°C. The peak temperature inside the device should be less than or  
equal to 220°C for a maximum of 10 seconds  
Wash  
Notes  
Ultrasonic cleaning is not recommended.  
ORDERING INFORMATION  
1.0  
2.0  
Vcc = 3.3Vdc, Vc = 1.65V  
Inclusive of calibration @ 25°C, frequency stability vs. temperature, supply and load variations, shock, vibration and  
aging for ten years. Control voltage (Vc) = 1.65 Vdc.  
Control voltage for (Fo) = 1.65 Vdc Typical. Positive Transfer Function.  
When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state
