## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground terminal; all device voltages are referenced to this pin. |
| 2 | SIN | input | Serial data input for the 17-bit common shift register; a high level writes a '1' to the LSB on each SCLK rising edge. |
| 3 | SCLK | input | Serial data shift clock; data on SIN are shifted into the LSB of the 17-bit shift register on each rising edge. |
| 4 | LAT | input | Data latch input; the rising edge of LAT latches the shift register data into the output on/off data latch and replaces the shift register contents with SID. |
| 5 | OUT0 | output | Constant-current sink output channel 0; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 6 | OUT1 | output | Constant-current sink output channel 1; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 7 | OUT2 | output | Constant-current sink output channel 2; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 8 | OUT3 | output | Constant-current sink output channel 3; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 9 | OUT4 | output | Constant-current sink output channel 4; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 10 | OUT5 | output | Constant-current sink output channel 5; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 11 | OUT6 | output | Constant-current sink output channel 6; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 12 | OUT7 | output | Constant-current sink output channel 7; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 13 | OUT8 | output | Constant-current sink output channel 8; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 14 | OUT9 | output | Constant-current sink output channel 9; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 15 | OUT10 | output | Constant-current sink output channel 10; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 16 | OUT11 | output | Constant-current sink output channel 11; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 17 | OUT12 | output | Constant-current sink output channel 12; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 18 | OUT13 | output | Constant-current sink output channel 13; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 19 | OUT14 | output | Constant-current sink output channel 14; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 20 | OUT15 | output | Constant-current sink output channel 15; absolute maximum output voltage is 11 V and output current is 65 mA, and outputs may be paralleled to increase current capability. |
| 21 | BLANK | input | Blank input; when high, all constant-current outputs are forced off, and when low, outputs follow the on/off control data in the data latch. |
| 22 | SOUT | output | Serial data output of the 17-bit common shift register, connected to its MSB and clocked out on the SCLK rising edge. |
| 23 | IREF | bidirectional | Maximum-current programming pin; a resistor from IREF to GND (1.32 kΩ to 66.0 kΩ, placed close to the device) sets the maximum current of every output, and tying IREF directly to GND forces all outputs off. |
| 24 | VCC | power_in | Power-supply voltage; the recommended supply range is 3.0 V to 5.5 V and the absolute maximum is 6.0 V. |
