TLC59283DBQR from Texas Instruments, in a SSOP-24-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power supply ground. |
| 2 | SIN | input | Serial data input for driver switch control; Schmitt buffer input, set logic high to shift '1' into shift register LSB or logic low to shift '0' on SCLK rising edge. |
| 3 | SCLK | input | Serial clock input; Schmitt buffer input, all data in 16-bit shift register shifted one bit toward MSB on each rising edge. |
| 4 | LAT | input | Latch input; Schmitt buffer input, when high shift register data continuously transfers to output latch, when low output latch data held, internally pulled down to GND through 500kΩ resistor. |
| 5 | OUT0 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 6 | OUT1 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 7 | OUT2 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 8 | OUT3 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 9 | OUT4 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 10 | OUT5 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 11 | OUT6 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 12 | OUT7 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 13 | OUT8 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 14 | OUT9 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 15 | OUT10 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 16 | OUT11 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 17 | OUT12 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 18 | OUT13 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 19 | OUT14 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 20 | OUT15 | output | Constant current sink output; independently controlled by output latch, capable of 2 to 45 mA depending on VCC and external reference resistor. |
| 21 | BLANK | input | Blanking control; Schmitt buffer input, when high forces all constant-current outputs off and enables all pre-charge FETs, when low outputs controlled by latch data, internally pulled up to VCC through 500kΩ resistor. |
| 22 | SOUT | output | Serial data output connected to 16-bit shift register MSB; output data transitions on SCLK rising edge. |
| 23 | IREF | input | Reference current input; external resistor connected between IREF and GND sets constant output current for all 16 outputs. |
| 24 | VCC | power_in | Power supply voltage input, 3.0V to 5.5V operating range. |
