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. |
