LM2902QT14-13 from Diodes Incorporated, in a TSSOP-14. 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 | 1OUT | output | Channel 1 output; short circuits to ground or to VCC must be of short duration because excessive chip dissipation can destroy the device. |
| 2 | 1IN- | input | Channel 1 inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 3 | 1IN+ | input | Channel 1 non-inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 4 | VCC | power_in | Chip supply voltage; the Recommended Operating Conditions give a single supply of 2 V to 36 V or a dual supply of ±1 V to ±18 V. |
| 5 | 2IN+ | input | Channel 2 non-inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 6 | 2IN- | input | Channel 2 inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 7 | 2OUT | output | Channel 2 output; short circuits to ground or to VCC must be of short duration because excessive chip dissipation can destroy the device. |
| 8 | 3OUT | output | Channel 3 output; short circuits to ground or to VCC must be of short duration because excessive chip dissipation can destroy the device. |
| 9 | 3IN- | input | Channel 3 inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 10 | 3IN+ | input | Channel 3 non-inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 11 | GND | power_in | Ground; for single-supply operation a minimum 0.1 µF bypass capacitor should be placed as close as possible between VCC and GND. |
| 12 | 4IN+ | input | Channel 4 non-inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 13 | 4IN- | input | Channel 4 inverting input; the input common-mode range is 0 V to VCC-1.5 V at +25°C (VCC-2.0 V over full temperature), and either input can go to +36 V without damage. |
| 14 | 4OUT | output | Channel 4 output; short circuits to ground or to VCC must be of short duration because excessive chip dissipation can destroy the device. |
