TCWIN T75: the six-pad version of T74 (12 V supply 9-14 V, 8.5 mA per channel, RGB order, 0.3 / 0.9 us timing, reset at least 200 us), cover rating 0.12 W, version A5 dated 2024-07-18. Pins: 1 GND, 2 DIN, 3 FDIN (backup data input), 4 VDD, 5 NC, 6 DO - the same pins and drawing as TX1818BJJ-F01 (tx1818-5050-6p). Its typical-application note advises a 33 ohm resistor in the supply line, 0.1 uF decoupling and a 330 ohm resistor in the signal input, to protect the pins against hot-plug spikes.
