# DIO1269LP10

**DIOO** · Analog Switches, Multiplexers · QFN-10(1.8x1.4)

DIO1269LP10 from DIOO, in a QFN-10(1.8x1.4). 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 | NO1 | passive | Normally-open analog switch terminal of switch 1, connected to COM1 when the select input is high (switch function per block diagram). |
| 2 | NC2 | unconnected | Normally-closed analog switch terminal of switch 2, switched to COM2 and capable of negative-swing audio signals. |
| 3 | NO2 | passive | Normally-open analog switch terminal of switch 2, switched to COM2. |
| 4 | GND | power_in | Ground pin. |
| 5 | COM2 | passive | Common port of switch 2, with power-off protection. |
| 6 | S2 | input | Select input for switch 2, TTL-level compatible with very low quiescent current when the control voltage is below VCC. |
| 7 | S1 | input | Select input for switch 1, TTL-level compatible with very low quiescent current when the control voltage is below VCC. |
| 8 | COM1 | passive | Common port of switch 1, with power-off protection. |
| 9 | VCC | power_in | Positive supply pin, operating range 2.7V to 4.5V. |
| 10 | NC1 | unconnected | Normally-closed analog switch terminal of switch 1, switched to COM1. |
