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 | LAT | input | Edge-triggered latch input that transfers the on/off control shift register data to the data latch on its rising edge, and LAT must be toggled only once after the shift data are updated. |+| 2 | OUT0 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA, and outputs may be tied together to increase current. |+| 3 | OUT1 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 4 | OUT2 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 5 | OUT3 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 6 | OUT4 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 7 | OUT5 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 8 | OUT6 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 9 | OUT7 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 10 | OUT8 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 11 | OUT9 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 12 | OUT10 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 13 | OUT11 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 14 | OUT12 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 15 | OUT13 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 16 | OUT14 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 17 | OUT15 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |+| 18 | BLANK | input | Blanks all constant-current outputs when high (outputs forced off) and enables the on/off data latch control when low; LOD and PTW data are latched on its rising edge. |+| 19 | SOUT | output | Serial data output connected to the MSB of the on/off data shift register, with data changing on the rising edge of SCLK; output voltage is limited to -0.3 V to VCC + 0.3 V. |+| 20 | IREF | bidirectional | Constant-current setting pin with an external resistor connected between IREF and GND that sets the sink current of OUT0 through OUT15. |+| 21 | VCC | power_in | Power-supply voltage, specified from 3.0 V to 5.5 V. |+| 22 | GND | power_in | Power ground; all GND lines should be made as wide and short as possible to limit parasitic inductance and resistance. |+| 23 | SIN | input | Serial data input for on/off control; when SIN is high, a '1' is written into the LSB of the on/off control shift register on the rising edge of SCLK. |+| 24 | SCLK | input | Serial data shift clock with Schmitt buffer input that shifts the on/off control shift register by one bit per rising edge, and a rising edge is allowed only 100 ns after a rising edge of LAT. |+| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-24(4x4) |+| Category | LED Drivers |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `TLC5928RGER`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.6x2.6mm`+- 3D model: VQFN-24(4x4) (KiCad packages3D, STEP)+- 3D model files: `tlc5928rger-etched.step` / `tlc5928rger-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
