Pin Number Pin Symbol

Description

1FC

Frequency Control for the internal oscillator. FC = open,

f

2

CAP+

Connect to the positive terminal of the charge pump capacitor.

3

GND

(Voltage Inverter Circuit) Ground.

3

GND

(Positive Voltage Doubler Circuit) Positive supply voltage

input.

4

CAP-

Connect to the negative terminal of the charge pump capacitor.

5

OUT

(Voltage Inverter Circuit) Negative voltage output pin.

5

OUT

(Positive Voltage Doubler Circuit) Ground pin for power

supply.

6LV

Low -voltage operation input pin in 660 circuits. In SP6661

circuits can be connected to GND, OUT or left open as desired

with no effect.

7

OSC

Control pin for the oscillator. Internally connected to 15pF

capacitor. An external capacitor can be added to slow the

oscillator. Be careful to minimize stray capacitance. An

external oscillator can be connected to overdrive the OSC pin.

8V+

(Voltage Inverter Circuit) Positive voltage input pin for the

power supply.

8V+

(Positive Voltage Doubler Circuit) Positive voltage output.
