E-L9637D013TR from STMicroelectronics, 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 | RX | output | Output for K as input with pull-up resistor to VCC. |
| 2 | LO | output | Output from L comparator with pull-up resistor to VCC. |
| 3 | VCC | power_in | Stabilized voltage supply rated 3 V to 7 V. |
| 4 | TX | input | TTL-compatible input for K with pull-up resistor to VCC. |
| 5 | GND | power_in | Common ground reference. |
| 6 | K | bidirectional | Bidirectional K line interface with supply voltage dependent threshold and 60 mA output current limitation. |
| 7 | VS | power_in | Supply voltage rated 4.5 V to 36 V with transient rated to 40 V and reverse battery protection to -24 V. |
| 8 | LI | input | Input to L comparator with supply voltage dependent threshold. |
