Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LAT | input | Level triggered latch input controlling shift register data transfer to output latch; internally pulled down to GND through 500kΩ resistor. |
| 2 | OUT0 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 3 | OUT1 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 4 | OUT2 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 5 | OUT3 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 6 | OUT4 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 7 | OUT5 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 8 | OUT6 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 9 | OUT7 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 10 | OUT8 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 11 | OUT9 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 12 | OUT10 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 13 | OUT11 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 14 | OUT12 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 15 | OUT13 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 16 | OUT14 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 17 | OUT15 | output | Constant current sink output (2mA to 45mA) that can be connected in parallel with other outputs to increase total current. |
| 18 | BLANK | input | All outputs blanked control input; high level forces all constant current outputs off and pre-charge FETs on, internally pulled up to VCC through 500kΩ resistor. |
| 19 | SOUT | output | Serial data output connected to 16-bit shift register MSB; output transitions on SCLK rising edge. |
| 20 | IREF | input | Constant current reference input; external resistor to GND sets output current in range 2mA to 45mA depending on VCC and resistor value. |
| 21 | VCC | power_in | Power supply voltage input; recommended operating range 3V to 5.5V. |
| 22 | GND | power_in | Power ground reference. |
| 23 | SIN | input | Serial data input for driver switch control; Schmitt buffer input that loads data into 16-bit shift register LSB on SCLK rising edge. |
| 24 | SCLK | input | Serial data shift clock input; Schmitt buffer input that shifts all 16-bit shift register data one bit toward MSB on each rising edge. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
