TLC59283RGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 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).
