TLC393QDR from Texas Instruments, 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 | 1OUT | output | Open-drain output of comparator 1; output voltage range -0.3 V to 16 V, output current up to 20 mA. |
| 2 | 1IN- | input | Inverting input of comparator 1; input voltage range -0.3 V to VDD. |
| 3 | 1IN+ | input | Noninverting input of comparator 1; input voltage range -0.3 V to VDD. |
| 4 | GND | power_in | Ground reference for the device; total current out of GND up to 40 mA. |
| 5 | 2IN+ | input | Noninverting input of comparator 2; input voltage range -0.3 V to VDD. |
| 6 | 2IN- | input | Inverting input of comparator 2; input voltage range -0.3 V to VDD. |
| 7 | 2OUT | output | Open-drain output of comparator 2; output voltage range -0.3 V to 16 V, output current up to 20 mA. |
| 8 | VDD | power_in | Positive supply voltage input; for the Q-grade device the recommended supply range is 4 V to 16 V. |
