TLC59281DBQR from Texas Instruments, 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 | Power ground. |
| 2 | SIN | input | Serial data input for on/off control; when high, data '1' are written into LSB of on/off control shift register at rising edge of SCLK. |
| 3 | SCLK | input | Serial data shift clock with Schmitt buffer input; shifts all data in on/off control shift register toward MSB by 1-bit at rising edge; rising edge allowed 100 ns after LAT rising edge. |
| 4 | LAT | input | Edge-triggered latch; on/off control data transferred from shift register to latch at rising edge; must toggle only once after shift data update. |
| 5 | OUT0 | output | Constant-current sink output; each output can be tied with others to increase current; output voltage range from -0.3 V to +18 V. |
| 6 | OUT1 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 7 | OUT2 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 8 | OUT3 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 9 | OUT4 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 10 | OUT5 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 11 | OUT6 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 12 | OUT7 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 13 | OUT8 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 14 | OUT9 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 15 | OUT10 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 16 | OUT11 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 17 | OUT12 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 18 | OUT13 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 19 | OUT14 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 20 | OUT15 | output | Constant-current sink output; output voltage range from -0.3 V to +18 V. |
| 21 | BLANK | input | Blank all outputs; when high, all constant-current outputs (OUT0-OUT15) forced off; when low, outputs controlled by on/off control latch data. |
| 22 | SOUT | output | Serial data output connected to MSB of on/off data shift register; data changes at rising edge of SCLK. |
| 23 | IREF | bidirectional | Constant-current value setting; OUT0-OUT15 sink constant-current set by connection of external resistor between IREF and GND; reference voltage VIREF = 1.20 V typical. |
| 24 | VCC | power_in | Power-supply voltage; operating range 3.0 V to 5.5 V. |
