LM393ADGKR from Texas Instruments, in a VSSOP-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 NPN output of comparator 1 that sinks current to GND when 1IN- exceeds 1IN+ plus offset voltage. |
| 2 | 1IN- | input | Negative input of comparator 1; input voltage range 0 to VCC - 2.0V over temperature. |
| 3 | 1IN+ | input | Positive input of comparator 1; input voltage range 0 to VCC - 2.0V over temperature. |
| 4 | GND | power_in | Ground; connection point for negative supply reference. |
| 5 | 2IN+ | input | Positive input of comparator 2; input voltage range 0 to VCC - 2.0V over temperature. |
| 6 | 2IN- | input | Negative input of comparator 2; input voltage range 0 to VCC - 2.0V over temperature. |
| 7 | 2OUT | output | Open-drain NPN output of comparator 2 that sinks current to GND when 2IN- exceeds 2IN+ plus offset voltage. |
| 8 | VCC | power_in | Positive supply voltage; operating range 2 to 30V for LM393/LM393A. |
