MBI5153GP-A from MBI, in a SSOP-24. 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	Ground reference for control logic and constant-current output sinks. Tie to system GND. IGND up to 360 mA.
2	SDI	input	Serial-data input to the 16-bit shift register. CMOS input, VIH ≥ 0.7·VDD, VIL ≤ 0.3·VDD. Sampled on DCLK rising edge.
3	DCLK	input	Data clock input; shifts SDI on the rising edge and carries command information when LE is asserted. Max FDCLK = 30 MHz (5V).
4	LE	input	Data strobe / latch enable and command-select terminal used with DCLK to encode commands (e.g. data-latch, Vsync). Has internal pull-down (~450 kΩ).
5	OUT0	output	Constant-current sink output channel 0 for driving an LED cathode. 0.5-20 mA @ 5V (0.5-10 mA @ 3.3V), sustaining voltage up to 17 V.
6	OUT1	output	Constant-current sink output channel 1 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
7	OUT2	output	Constant-current sink output channel 2 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
8	OUT3	output	Constant-current sink output channel 3 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
9	OUT4	output	Constant-current sink output channel 4 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
10	OUT5	output	Constant-current sink output channel 5 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
11	OUT6	output	Constant-current sink output channel 6 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
12	OUT7	output	Constant-current sink output channel 7 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
13	OUT8	output	Constant-current sink output channel 8 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
14	OUT9	output	Constant-current sink output channel 9 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
15	OUT10	output	Constant-current sink output channel 10 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
16	OUT11	output	Constant-current sink output channel 11 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
17	OUT12	output	Constant-current sink output channel 12 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
18	OUT13	output	Constant-current sink output channel 13 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
19	OUT14	output	Constant-current sink output channel 14 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
20	OUT15	output	Constant-current sink output channel 15 for LED cathode drive. 0.5-20 mA @ 5V, VDS up to 17 V.
21	GCLK	input	Gray-scale clock input. Drives the internal PWM counter for grayscale comparison. Max 33 MHz (5V, direct) / 16.6 MHz when GCLK multiplier is enabled.
22	SDO	output	Serial-data output; connects to SDI of the next MBI5153 in the cascade. Push-pull CMOS, VOH ≥ VDD-0.4 V at -1 mA.
23	R-EXT	passive	External reference-resistor pin; a resistor from R-EXT to GND sets the global constant-current level for all 16 OUT channels (typ. 1.4 kΩ-14 kΩ).
24	VDD	power_in	3.3 V / 5 V logic supply (absolute range 3.0-5.5 V; abs max 7 V). Decouple locally with 100 nF + 10 µF to GND.
