LM393APWR 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 | 1OUT | output | Output pin of comparator 1; output voltage range -0.3 to 36V; low output saturation voltage; compatible with TTL, MOS, and CMOS logic. |
| 2 | 1IN− | input | Negative input pin of comparator 1; input voltage range 0 to (VCC - 2.0V); differential input voltage range ±36V maximum. |
| 3 | 1IN+ | input | Positive input pin of comparator 1; input voltage range 0 to (VCC - 2.0V); differential input voltage range ±36V maximum. |
| 4 | GND | power_in | Ground; provides 0V reference for all voltage measurements. |
| 5 | 2IN+ | input | Positive input pin of comparator 2; input voltage range 0 to (VCC - 2.0V); differential input voltage range ±36V maximum. |
| 6 | 2IN− | input | Negative input pin of comparator 2; input voltage range 0 to (VCC - 2.0V); differential input voltage range ±36V maximum. |
| 7 | 2OUT | output | Output pin of comparator 2; output voltage range -0.3 to 36V; low output saturation voltage; compatible with TTL, MOS, and CMOS logic. |
| 8 | VCC | power_in | Positive supply voltage; recommended operating range 2 to 30V; absolute maximum rating 36V for non-B versions. |
