TLC59711PWPR

Texas Instruments · LED Drivers · HTSSOP-20-EP

TLC59711PWPR 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 External resistor to GND sets maximum constant-current output level for all channels; all outputs forced off if directly connected to GND.
2 GND power_in Power ground terminal.
3 OUTR0 output RED constant-current sink output; multiple red outputs can be paralleled to increase current capability with different voltages applied to each.
4 OUTG0 output GREEN constant-current sink output; multiple green outputs can be paralleled to increase current capability with different voltages applied to each.
5 OUTB0 output BLUE constant-current sink output; multiple blue outputs can be paralleled to increase current capability with different voltages applied to each.
6 OUTR1 output RED constant-current sink output; multiple red outputs can be paralleled to increase current capability with different voltages applied to each.
7 OUTG1 output GREEN constant-current sink output; multiple green outputs can be paralleled to increase current capability with different voltages applied to each.
8 OUTB1 output BLUE constant-current sink output; multiple blue outputs can be paralleled to increase current capability with different voltages applied to each.
9 SDTI input Serial data input for the 224-bit shift register.
10 SCKI input Serial data shift clock input; data shifted to LSB on rising edge with MSB appearing on SDTO.
11 SCKO output Serial data shift clock output synchronized to SDTO timing.
12 SDTO output Serial data output from MSB of 224-bit shift register with data clocked out at falling edge of SCKO.
13 OUTR2 output RED constant-current sink output; multiple red outputs can be paralleled to increase current capability with different voltages applied to each.
14 OUTG2 output GREEN constant-current sink output; multiple green outputs can be paralleled to increase current capability with different voltages applied to each.
15 OUTB2 output BLUE constant-current sink output; multiple blue outputs can be paralleled to increase current capability with different voltages applied to each.
16 OUTR3 output RED constant-current sink output; multiple red outputs can be paralleled to increase current capability with different voltages applied to each.
17 OUTG3 output GREEN constant-current sink output; multiple green outputs can be paralleled to increase current capability with different voltages applied to each.
18 OUTB3 output BLUE constant-current sink output; multiple blue outputs can be paralleled to increase current capability with different voltages applied to each.
19 VCC power_in Power-supply terminal.
20 VREG bidirectional 3.3 V regulated output with 1 µF decoupling capacitor required; can be externally supplied with 3 V to 5.5 V.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TLC59711PWPR
  • Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
  • 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tlc59711pwpr-etched.step / tlc59711pwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc59711pwpr.step / tlc59711pwpr.glb are the bare package body.
