Pin Functions

PIN TYPE DESCRIPTION
NUMBER NAME VOLTAGE INVERTER VOLTAGE DOUBLER
1 FC Input Frequency control for internal oscillator: Same as inverter.
FC = open, fOSC = 10 kHz (typ);
FC = V+, fOSC = 80 kHz (typ);
FC has no effect when OSC pin is driven externally.
2 CAP+ Power Connect this pin to the positive terminal of charge-pump capacitor. Same as inverter.
3 GND Ground Power supply ground input. Power supply positive voltage input.
4 CAP− Power Connect this pin to the negative terminal of charge-pump capacitor. Same as inverter.
5 OUT Power Negative voltage output. Power supply ground input.
6 LV Input Low-voltage operation input. Tie LV to GND when input voltage is less than 3.5 V. Above 3.5 V, LV can be connected to GND or left open. When driving OSC with an external clock, LV must be connected to GND. LV must be tied to OUT.
7 OSC Input Oscillator control input. OSC is connected to an internal 15-pF capacitor. An external capacitor can be connected to slow the oscillator. Also, an external clock can be used to drive OSC. Same as inverter except that OSC cannot be driven by an external clock.
8 V+ Power Power supply positive voltage input. Positive voltage output.
