TLC59711PWP from Texas Instruments, in a HTSSOP-20-EP. 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 | IREF | input | Current reference input; a resistor connected between IREF and GND sets the maximum output current for all 12 channels, with outputs forced off when directly connected to GND. |
| 2 | GND | power_in | Power ground terminal. |
| 3 | OUTR0 | output | Red constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 4 | OUTG0 | output | Green constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 5 | OUTB0 | output | Blue constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 6 | OUTR1 | output | Red constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 7 | OUTG1 | output | Green constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 8 | OUTB1 | output | Blue constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 9 | SDTI | input | Serial data input for the 224-bit shift register; data present on SDTI are shifted to the LSB at each SCKI rising edge. |
| 10 | SCKI | input | Serial data shift clock input; data in the shift register are shifted toward the MSB at each SCKI rising edge with MSB data appearing on SDTO. |
| 11 | SCKO | output | Serial data shift clock output; the input shift clock signal from SCKI is adjusted to the timing of the serial data output for SDTO. |
| 12 | SDTO | output | Serial data output of the 224-bit shift register; connected to the MSB with data clocked out at the falling edge SCKO. |
| 13 | OUTR2 | output | Red constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 14 | OUTG2 | output | Green constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 15 | OUTB2 | output | Blue constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 16 | OUTR3 | output | Red constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 17 | OUTG3 | output | Green constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 18 | OUTB3 | output | Blue constant-current output; maximum 60 mA per channel, can be configured in parallel for increased current capability, different voltages can be applied to each output. |
| 19 | VCC | power_in | Power-supply terminal; accepts supply voltage from 4.0 V to 17 V for the internal linear regulator. |
| 20 | VREG | bidirectional | Internal linear voltage regulator output providing 3.3 V with a 1 µF decoupling capacitor required; can supply external circuits or be supplied externally with 3.0 V to 5.5 V, and can be connected with VREG terminals of other devices to increase supply current. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
