E-L9637D013TR

STMicroelectronics · Interface - Specialized · SOIC-8

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.
