TCWIN T65: a 2.0 x 1.7 x 0.85 mm built-in-IC LED, 12 mA per channel (typical only), version A0 dated 2024-07-27. Pins 1 DO, 2 GND, 3 DIN, 4 VDD (drawing and table agree). Supply 3.0-5.5 V, operating range -30 to 70 C (narrower than the -40 to 85 C of the other sheets), ESD 5.5 kV. T65 and T77 (5050) print the same electrical and timing tables.

Datasheets disagree with themselves: the sheet calls the body a “0807 LED” while its dimensions are 2.0 x 1.7 mm and its sibling T63/T64 call the same drawing “2017”; the cover prints “1.7 x 2.0 x 0.85” where the others print “2.0 x 1.7 x 0.85”; the logic-input absolute maximum is printed as -0.5 to 0.5 V (almost certainly a typo for 5.5 V); and the timing table gives T1L as 600/900/- ns and T1H as 600/800/900 ns, i.e. a one-code low time as long as the zero-code low time, which cannot describe a working return-to-zero code. Treat the T1L window as a sheet error until measured.

Outline and pin positions checked against the manufacturer datasheet (C48982518 T65 rev A0 p4). Half-moon notched pads at the two 2.0 mm ends (drawn square). The sheet shows a green bar / triangle mark and does not say what it denotes; pins are numbered in the top view. Pad size 0.52 x 0.70 mm, 0.97 mm between inner edges, 0.20 mm gap. 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.
