OUTPUT LOAD (A)
All specifications are typical at nominal input, full load, and 25DegC unless
otherwise noted
* These are stress ratings. Exposure of the devices to any of these conditions
may adversely affect long term reliability. Proper operation under conditions
other than the standard operating conditions is neither warranteed nor implied.

APPLICATION OF SYNCHRONIZATION
1. The unit is capable of external synchronization from an independent
time base with a switching rate between 200kHz and 215kHz
2. The amplitude of the synchronizing pulse train is TTL compatible
3. The duty cycle of the CLK should be 20% high and 80% low
4. Synchronization is referenced to negative input (-Vin)
