ICL7660CBAZ-T from Intersil(Renesas Electronics), in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | The datasheet pinout labels this pin NC and gives it no electrical function. |
| 2 | CAP+ | passive | Positive terminal of the external pump capacitor C1, which must be connected to this pin when polarized capacitors are used. |
| 3 | GND | power_in | Ground reference; the output (pin 5) must not go more positive than this pin or the device can latch up. |
| 4 | CAP- | passive | Negative terminal of the external pump capacitor C1 in the charge pump, connected between pins 2 and 4 in the test circuit. |
| 5 | VOUT | power_out | Negative converter output that gives -V+ (or -nV+ when cascaded) and must not be driven more positive than GND. |
| 6 | LV | input | Low-voltage pin that is tied to GND for supply voltages up to 3.5V and must be left floating above 3.5V to prevent latchup. |
| 7 | OSC | input | Oscillator terminal where an external capacitor can lower the nominal 10kHz frequency or an external clock can overdrive it. |
| 8 | V+ | power_in | Positive supply input with a 1.5V to 10.0V operating range for the ICL7660 and 1.5V to 12.0V for the ICL7660A, with an absolute maximum of +10.5V and +13.0V respectively. |
