LV
Low-Voltage Operation Input. Tie LV to VSS
when input voltage is less than 2V. Above
2V, LV must be left open.
Oscillator Control Input. SYNC is connected
to an internal 15pF capacitor. An external
Oscillator may be connected to overdrive
SYNC via a 2…5nF capacitor.
SYNC shall not be connected to ground.
