LM239DR-JSM from JSMSEMI, in a SOP-14. 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 | OUT2 | output | Output of comparator 2; open-collector output with 16 mA typical sink current and 130 mV typical saturation voltage. |
| 2 | OUT1 | output | Output of comparator 1; open-collector output with 16 mA typical sink current and 130 mV typical saturation voltage. |
| 3 | VCC | power_in | Positive supply; absolute maximum 36 V (or ±18 V split supply). |
| 4 | IN1(-) | input | Inverting input of comparator 1; common-mode range -0.3 V to VCC absolute maximum. |
| 5 | IN1(+) | input | Non-inverting input of comparator 1; common-mode range -0.3 V to VCC absolute maximum. |
| 6 | IN2(-) | input | Inverting input of comparator 2; common-mode range -0.3 V to VCC absolute maximum. |
| 7 | IN2(+) | input | Non-inverting input of comparator 2; common-mode range -0.3 V to VCC absolute maximum. |
| 8 | IN3(-) | input | Inverting input of comparator 3; common-mode range -0.3 V to VCC absolute maximum. |
| 9 | IN3(+) | input | Non-inverting input of comparator 3; common-mode range -0.3 V to VCC absolute maximum. |
| 10 | IN4(-) | input | Inverting input of comparator 4; common-mode range -0.3 V to VCC absolute maximum. |
| 11 | IN4(+) | input | Non-inverting input of comparator 4; common-mode range -0.3 V to VCC absolute maximum. |
| 12 | GND | power_in | Ground, the negative supply reference. |
| 13 | OUT4 | output | Output of comparator 4; open-collector output with 16 mA typical sink current and 130 mV typical saturation voltage. |
| 14 | OUT3 | output | Output of comparator 3; open-collector output with 16 mA typical sink current and 130 mV typical saturation voltage. |
