TLC59711PWP

Texas Instruments · LED Drivers · HTSSOP-20-EP

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).

Manufacturer Texas Instruments
Package HTSSOP-20-EP
Category Nixie Tube Driver/LED Driver

CAD (KiCad official)

  • Symbol: TLC59711PWP
  • 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: tlc59711pwp-etched.step / tlc59711pwp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc59711pwp.step / tlc59711pwp.glb are the bare package body.
