The sheets name no IC; the cell is called ‘3-channels LED driver with 8 bit PWM linear control’ (19-C47, 12-23C, 4516-IC, 61-236-IC). The same electrical tables (DIN to DOUT delay, fall time, input capacitance, 0.35 V hysteresis, ‘DIN / SET’ thresholds) reappear word for word in the Lite-On LTST sheets and the Lumex SMD-LX0707RGB-TR sheet; the Lumex part also reuses the 12-23C timing and 5 V application figure. That suggests one IC supplied to several LED makers, but no sheet says so. Lumex’s sheet is reused on this protocol; Lite-On’s variants live in liteon-ic.
Refresh & flicker
800 kbps (‘Clock frequency 800 kbps’ in the absolute maximum table), 8 bit PWM per channel (256 grey levels), 24 bit per pixel sent R first, then G, then B, MSB first (figure ‘Single Data in 24bit for RGB’: OUTR[7]…OUTR[0], OUTG[7]…, OUTB[7]…). The 12-23C / 19-C47 sheets give a DIN to DOUT delay of 300 ns max (CL 15 pF, RL 10 k) and a 20 us falling time on the output with 300 pF; the 4516 and 61-236 sheets list a 0.35 V hysteresis and a DIN / SET input. Supply: abs max 3.8-5.5 V (12-23C), 4.2-5.5 V (19-C47, 61-236) and 6.5 V (4516); recommended 5 V typical. The sheets print no PWM frequency.
Timing
Sources disagree. This is normal and worth understanding: FastLED's numbers are tuned to drive real parts reliably, including clones, while the datasheet gives the manufacturer's nominal figures. Both are recorded here rather than picking one and hiding the conflict.
| Source | T0H | T0L | T1H | T1L | Period | Rate | Reset | ± |
|---|---|---|---|---|---|---|---|---|
| datasheet ↗ | 300 ns | 900 ns | 900 ns | 300 ns | 1200 ns | 833 kHz | 50 µs | 80 ns |
| T0H 300 ns +/-80, T0L 900 ns +/-80, T1H 900 ns +/-80, T1L 300 ns +/-80, reset >50 us. The cascade figure adds ‘>1.2 us ~ <3.6 us’ between 24-bit words. | ||||||||
| datasheet ↗ | 300 ns | 900 ns | 900 ns | 300 ns | 1200 ns | 833 kHz | 250 µs | 150 ns |
| Same typicals with +/-0.15 us. The reset row of this sheet reads ‘RES: low voltage time above 250 us’ while the waveform below it and the description (p1, ‘reset signal (>50us low-level signal)’) say ‘Latch time >50 us’. | ||||||||
Clones & compatibility
“Compatible” is never stated bare here — each relationship carries how strong the claim is, and what bites if you assume too much.
-
protocol compatible
ABOC BB single-wire IC (RGB order)
Same 300 / 900 / 900 / 300 ns split and the same R, G, B (not G, R, B) data order as the ABOC BB sheets; the tolerance (+/-80 ns here, 200-400 / 650-1000 ns windows there) and the reset (50 us here, 200 us there) differ. Neither maker names the other's IC. source ↗
-
protocol compatible of this
Lite-On embedded single-wire IC (LTST series)
The timing table (300 / 900 / 900 / 300 ns), the R, G, B order and the DIN-to-DOUT / fall-time / 0.35 V hysteresis electrical tables match the Everlight and Lumex sheets number for number; tolerance and reset differ between the Lite-On sheets themselves. No sheet names a common IC.

Dating evidence
Evidence, not a release date. A library commit proves the part existed by that date and says nothing about how long before.
