Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LAT | input | Rising-edge-triggered latch input that transfers on/off control data from shift register to data latch. |
| 2 | OUT0 | output | Constant-current sink output rated 2-35 mA; accepts up to 17 V and can be paralleled with other outputs. |
| 3 | OUT1 | output | Constant-current sink output rated 2-35 mA. |
| 4 | OUT2 | output | Constant-current sink output rated 2-35 mA. |
| 5 | OUT3 | output | Constant-current sink output rated 2-35 mA. |
| 6 | OUT4 | output | Constant-current sink output rated 2-35 mA. |
| 7 | OUT5 | output | Constant-current sink output rated 2-35 mA. |
| 8 | OUT6 | output | Constant-current sink output rated 2-35 mA. |
| 9 | OUT7 | output | Constant-current sink output rated 2-35 mA. |
| 10 | OUT8 | output | Constant-current sink output rated 2-35 mA. |
| 11 | OUT9 | output | Constant-current sink output rated 2-35 mA. |
| 12 | OUT10 | output | Constant-current sink output rated 2-35 mA. |
| 13 | OUT11 | output | Constant-current sink output rated 2-35 mA. |
| 14 | OUT12 | output | Constant-current sink output rated 2-35 mA. |
| 15 | OUT13 | output | Constant-current sink output rated 2-35 mA. |
| 16 | OUT14 | output | Constant-current sink output rated 2-35 mA. |
| 17 | OUT15 | output | Constant-current sink output rated 2-35 mA. |
| 18 | BLANK | input | Active-high input that forces all constant-current outputs OFF; outputs controlled by on/off data latch when BLANK is low. |
| 19 | SOUT | output | Serial data output connected to MSB of on/off shift register, changing at each rising edge of SCLK. |
| 20 | IREF | bidirectional | Reference input connected to external resistor between IREF and GND to set constant-current sink value of all output channels. |
| 21 | VCC | power_in | Power supply input, operating range 3.0 V to 5.5 V. |
| 22 | GND | power_in | Power ground connection. |
| 23 | SIN | input | Serial data input that writes data '1' to LSB of on/off control shift register at rising edge of SCLK when SIN is high level. |
| 24 | SCLK | input | Serial data shift clock input (Schmitt-buffered), 35 MHz maximum; shifts on/off control data 1 bit per rising edge with 10 ns minimum pulse widths. |
| 25 | Thermal Pad | power_in | Exposed thermal pad (bottom side) that must be soldered to board ground for thermal and mechanical performance; not connected internally. |
