Low-Voltage Operation Input. Tie LV to GND when input
voltage is less than 3V. Above 3V, LV may be connected to
GND or left open; when overdriving OSC, LV must be
connected to GND.
Oscillator Control Input. OSC is connected to an internal
15pF capacitor. An external capacitor can be added to slow
the oscillator. Take care to minimize stray capacitance. An
external oscillator may also be connected to overdrive OSC.
