**Texas Instruments** · Comparators · TSSOP-8

LM393LVPWR from Texas Instruments, in a TSSOP-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 | OUT1 | output | Output pin of comparator 1; open-drain configuration with typical 600 ns propagation delay. |
| 2 | IN1- | input | Inverting input pin of comparator 1; input voltage range -0.1 V to 5.6 V from GND, input bias current 5 pA typical. |
| 3 | IN1+ | input | Noninverting input pin of comparator 1; input voltage range -0.1 V to 5.6 V from GND, input bias current 5 pA typical. |
| 4 | GND | power_in | Negative supply; ground reference for the device. |
| 5 | IN2+ | input | Noninverting input pin of comparator 2; input voltage range -0.1 V to 5.6 V from GND, input bias current 5 pA typical. |
| 6 | IN2- | input | Inverting input pin of comparator 2; input voltage range -0.1 V to 5.6 V from GND, input bias current 5 pA typical. |
