TCWIN’s 12 V single-wire LED IC in a four-pad 5050 package: supply 10.8-13.2 V (12 V typ), absolute maximum -0.4 to 14 V, 9 mA per channel (8.82-9.18), cover rating 0.12 W, version A2 dated 2023-03-27, ESD 2 kV. Pins 1 VDD, 2 DO, 3 GND, 4 DIN (same drawing as the 5 V TX1812 5050 parts: plugging a TX1818 into a TX1812 footprint would put 12 V rails on a 5.5 V-limited part and vice versa). Data order is R, G, B (red first), unlike the GRB order of the 5 V TX1812/TX1813 sheets.
The sheet prints a reset of at least 80 us and 0.3 / 0.9 / 0.9 / 0.3 us timing ±0.05 us.
TX1818CWCJ-F01 has no datasheet on LCSC; listed by the shared IC code 1818 and package letter C (inference).

| No datasheet is listed on LCSC for this SKU. Package, pin order and drawing are taken from the sibling sheet TX1818CXJ-F01 because both share IC code 1818 and package letter C; that is an inference from the part number, not something any sheet states. Drive current, timing window and the meaning of the remaining letters are not confirmed for this SKU. LCSC stock 965 on 2026-10-15. | ||||||||

Outline and pin positions checked against the manufacturer datasheet (C784551 TX1818CXJ-F01 rev A2 p4). Pin 1 is top-left, numbering runs counter-clockwise, and the chamfer sits at pin 3 (GND), as in the WS2812B. The sheet marks "+" on the pin 1-2 side and "-" on the pin 3-4 side. Pad sizes read from the drawing; the part spans 5.4 mm across the leads. What this means.

Dating evidence
Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
