L9637D
L9637D is a K-line interface IC used to connect logic circuitry to an automotive diagnostic communication line. In a diagnostic interface design, it handles the line-facing function while the controller manages communication. The KiCad download includes an 8-pin symbol, the 8-pad SOP-8_L4.9-W3.9-P1.27-LS6.0-BL footprint, and a 3D model for inspecting placement in the board assembly. Its surface-mount small-outline package has leads along two sides. The files originate from a real ProtoFlow import that was converted and checked in the editor. Open the L9637D files directly in ProtoFlow to continue schematic and PCB work.
