TSX3704IQ4T from STMicroelectronics, in a QFN-16(3x3). 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 | VCC+ | power_in | Positive supply, operating range 2.7 V to 16 V (18 V absolute maximum); decouple with a 0.1 µF capacitor close to the supply pins. |
| 2 | IN-1 | input | Inverting input of comparator 1, common-mode range 0 V to (VCC+) - 1.5 V. |
| 3 | NC | unconnected | Not connected. |
| 4 | IN+1 | input | Non-inverting input of comparator 1, common-mode range 0 V to (VCC+) - 1.5 V. |
| 5 | IN-2 | input | Inverting input of comparator 2, common-mode range 0 V to (VCC+) - 1.5 V. |
| 6 | IN+2 | input | Non-inverting input of comparator 2, common-mode range 0 V to (VCC+) - 1.5 V. |
| 7 | IN-3 | input | Inverting input of comparator 3, common-mode range 0 V to (VCC+) - 1.5 V. |
| 8 | IN+3 | input | Non-inverting input of comparator 3, common-mode range 0 V to (VCC+) - 1.5 V. |
| 9 | IN-4 | input | Inverting input of comparator 4, common-mode range 0 V to (VCC+) - 1.5 V. |
| 10 | NC | unconnected | Not connected. |
| 11 | IN+4 | input | Non-inverting input of comparator 4, common-mode range 0 V to (VCC+) - 1.5 V. |
| 12 | VCC- | power_in | Negative supply or ground reference of the device. |
| 13 | OUT4 | output | Push-pull output of comparator 4, 18 V absolute maximum, 20 mA maximum output current. |
| 14 | OUT3 | output | Push-pull output of comparator 3, 18 V absolute maximum, 20 mA maximum output current. |
| 15 | OUT2 | output | Push-pull output of comparator 2, 18 V absolute maximum, 20 mA maximum output current. |
| 16 | OUT1 | output | Push-pull output of comparator 1, 18 V absolute maximum, 20 mA maximum output current. |
| 17 | EP | unconnected | Exposed pad, not internally connected; can be connected to VCC- or left floating. |
