LM393LVDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | tri_state | Open-drain output of comparator 1 with VOL ≤ 300 mV maximum over -40 to +125°C at 4 mA sink current, maximum sink current 100 mA per channel. |
| 2 | IN1- | input | Inverting input of comparator 1, accepts input voltage from -0.1 V to 5.6 V with 5 pA typical input bias current. |
| 3 | IN1+ | input | Noninverting input of comparator 1, accepts input voltage from -0.1 V to 5.6 V with 5 pA typical input bias current. |
| 4 | GND | power_in | Ground, negative power supply pin. |
| 5 | IN2+ | input | Noninverting input of comparator 2, accepts input voltage from -0.1 V to 5.6 V with 5 pA typical input bias current. |
| 6 | IN2- | input | Inverting input of comparator 2, accepts input voltage from -0.1 V to 5.6 V with 5 pA typical input bias current. |
| 7 | OUT2 | tri_state | Open-drain output of comparator 2 with VOL ≤ 300 mV maximum over -40 to +125°C at 4 mA sink current, maximum sink current 100 mA per channel. |
| 8 | V+ | power_in | Positive power supply, operates over 1.65 V to 5.5 V supply voltage range. |
