LMV393QDRQ1 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-collector output of comparator 1, with the output voltage limited to VCC+ + 0.3 V under the recommended operating conditions. |
| 2 | 1IN- | input | Inverting input of comparator 1, with the input voltage range limited to 0 V to 5.5 V (absolute maximum, either input). |
| 3 | 1IN+ | input | Non-inverting input of comparator 1, with the input voltage range limited to 0 V to 5.5 V (absolute maximum, either input). |
| 4 | GND | power_in | Network ground reference; all voltage values in the datasheet are measured with respect to this pin. |
| 5 | 2IN+ | input | Non-inverting input of comparator 2, with the input voltage range limited to 0 V to 5.5 V (absolute maximum, either input). |
| 6 | 2IN- | input | Inverting input of comparator 2, with the input voltage range limited to 0 V to 5.5 V (absolute maximum, either input). |
| 7 | 2OUT | output | Open-collector output of comparator 2, with the output voltage limited to VCC+ + 0.3 V under the recommended operating conditions. |
| 8 | VCC+ | power_in | Positive supply; the datasheet specifies 2.7 V to 5.5 V for single-supply operation. |
