TM512BCE from TM Shenzhen Titan Micro Elec, in a SSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Power supply negative (ground) reference for the logic and constant-current output stages.
2	OUTR	output	PWM constant-current output channel R. Open-drain sink, withstand >30 V, programmable 3-80 mA set by REXT, 16-bit gamma-corrected grayscale.
3	OUTG	output	PWM constant-current output channel G. Open-drain sink, withstand >30 V, programmable 3-80 mA set by REXT, 16-bit gamma-corrected grayscale.
4	OUTB	output	PWM constant-current output channel B. Open-drain sink, withstand >30 V, programmable 3-80 mA set by REXT, 16-bit gamma-corrected grayscale.
5	REXT	passive	Constant-current feedback / current-set pin. External resistor to GND programs the per-channel output current per Iout=48/(400+Rext); must not be left floating.
6	ADRO	output	Address programming line output. Push-pull output used to daisy-chain the address-writing signal to the next IC on the string. Drives at least ±10 mA at Vo=0.4 V / 4.0 V.
7	ADRI	input	Address programming line input with internal pull-up. Receives the address-write signal from the writer/controller or from the previous chip's ADRO in a chain.
8	AI	input	DMX512 differential signal input, positive polarity, with internal pull-up. Common-mode range up to 8 V, differential input impedance ~280 kΩ, threshold ±0.2 V, 70 mV hysteresis.
9	BI	input	DMX512 differential signal input, negative polarity, with internal pull-down. Paired with AI for the DMX512 differential receiver (auto-adaptive 200 kbps-1 Mbps).
10	VDD	power_in	Logic supply positive input. Recommended 3.8 V (min) / 5.5 V (typ) / 6 V (max); absolute max 6.5 V. Internal 5 V regulator/zener present; decouple with 104 (100 nF) to GND per application note.
