MBI5035GP-B from MBI, in a SSOP-24-150mil. 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 terminal for control logic and the constant-current sink outputs. Tie to system 0 V; carries up to 800 mA (I_GND max) when all 16 channels are conducting.
2 SDI input Serial-data input to the 16-bit shift register. Schmitt-trigger CMOS input; data is clocked in on the rising edge of CLK (t_su(D) ≥ 3 ns, t_h(D) ≥ 5 ns). V_IH ≥ 0.7·V_DD, V_IL ≤ 0.3·V_DD.
3 CLK input Shift-register clock input. Data on SDI is sampled on the rising edge of CLK; f_CLK up to 25 MHz at V_DD = 5 V (20 MHz at 3.3 V). Schmitt-trigger CMOS input.
4 LE input Latch-enable (data strobe) input. Shift-register data is transferred to the output latch while LE is high and held when LE goes low. Internally pulled down (R_IN(down) ≈ 500 kΩ typ, 250 kΩ - 800 kΩ).
5 OUT0 output Constant-current LED sink output, channel 0 (open-drain). Programmable 3-45 mA at V_DD = 5 V (3-30 mA at 3.3 V) via R-EXT. Sustains up to 17 V at V_DS with low knee voltage (0.2 V typ @ 20 mA).
6 OUT1 output Constant-current LED sink output, channel 1. Same electrical spec as OUT0; staggered ~5 ns after even channels to reduce peak supply current.
7 OUT2 output Constant-current LED sink output, channel 2. Same spec as OUT0 (3-45 mA @ V_DD=5V, V_DS ≤ 17 V).
8 OUT3 output Constant-current LED sink output, channel 3. Same spec as OUT0.
9 OUT4 output Constant-current LED sink output, channel 4. Same spec as OUT0.
10 OUT5 output Constant-current LED sink output, channel 5. Same spec as OUT0.
11 OUT6 output Constant-current LED sink output, channel 6. Same spec as OUT0.
12 OUT7 output Constant-current LED sink output, channel 7. Same spec as OUT0.
13 OUT8 output Constant-current LED sink output, channel 8. Same spec as OUT0.
14 OUT9 output Constant-current LED sink output, channel 9. Same spec as OUT0.
15 OUT10 output Constant-current LED sink output, channel 10. Same spec as OUT0.
16 OUT11 output Constant-current LED sink output, channel 11. Same spec as OUT0.
17 OUT12 output Constant-current LED sink output, channel 12. Same spec as OUT0.
18 OUT13 output Constant-current LED sink output, channel 13. Same spec as OUT0.
19 OUT14 output Constant-current LED sink output, channel 14. Same spec as OUT0.
20 OUT15 output Constant-current LED sink output, channel 15. Same spec as OUT0.
21 /OE input Active-low output enable. When /OE is low, all 16 constant-current output drivers are enabled; when high, all outputs are turned off (blanked). Internally pulled up (R_IN(up) ≈ 500 kΩ typ, 250 kΩ - 800 kΩ), so the outputs default to OFF if the pin is left floating.
22 SDO output Serial-data output - feeds the SDI of the next cascaded driver. Push-pull CMOS output (V_OH ≥ V_DD-0.4 V @ -1 mA, V_OL ≤ 0.4 V @ 1 mA). SDO updates on the rising edge of CLK.
23 R-EXT passive External reference-resistor terminal. A resistor (R_ext) from this pin to GND sets the constant output current for all 16 channels: I_OUT = (V_R-EXT/R_ext)·15 with V_R-EXT = 1.24 V (e.g. 930 Ω → ~20 mA, 1860 Ω → ~10 mA).
24 VDD power_in Logic supply, 3.0-3.6 V or 4.5-5.5 V (nominal 3.3 V / 5.0 V). Decouple to GND with a 100 nF ceramic close to the pin plus a bulk capacitor (22 µF typ). Absolute maximum 7 V.
