TLC59108IRGYR from Texas Instruments, in a VQFN-20-EP(3.7x4.7). 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 | REXT | passive | Input terminal used to connect an external resistor that sets the constant output current for all outputs, which the datasheet gives as 10 mA to 120 mA. |
| 2 | A0 | input | Hardware address input 0 that, together with A1 to A3, selects one of up to 14 I2C bus addresses; inputs must be held at VCC or GND when unused. |
| 3 | A1 | input | Hardware address input 1 that, together with A0, A2 and A3, selects the I2C bus address; VIH is 0.7 × VCC minimum and VIL is 0.3 × VCC maximum. |
| 4 | A2 | input | Hardware address input 2 that, together with A0, A1 and A3, selects the I2C bus address; VIH is 0.7 × VCC minimum and VIL is 0.3 × VCC maximum. |
| 5 | A3 | input | Hardware address input 3 that, together with A0 to A2, selects the I2C bus address; VIH is 0.7 × VCC minimum and VIL is 0.3 × VCC maximum. |
| 6 | OUT0 | output | Constant-current LED sink output 0 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 7 | OUT1 | output | Constant-current LED sink output 1 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 8 | GND | power_in | Ground connection. |
| 9 | OUT2 | output | Constant-current LED sink output 2 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 10 | OUT3 | output | Constant-current LED sink output 3 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 11 | OUT4 | output | Constant-current LED sink output 4 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 12 | OUT5 | output | Constant-current LED sink output 5 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 13 | GND | power_in | Ground connection. |
| 14 | OUT6 | output | Constant-current LED sink output 6 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 15 | OUT7 | output | Constant-current LED sink output 7 that turns the LED on at a low level, rated for 5 mA to 120 mA with a maximum output voltage of 17 V. |
| 16 | GND | power_in | Ground connection. |
| 17 | RESET | input | Active-low reset input; VIH is 0.7 × VCC minimum and VIL is 0.3 × VCC maximum. |
| 18 | SCL | input | I2C serial clock input; VIH is 0.7 × VCC minimum and VIL is 0.3 × VCC maximum, and the input has a noise filter. |
| 19 | SDA | bidirectional | I2C serial data input/output with 30-mA high drive capability for driving high-capacitance buses; VIH is 0.7 × VCC minimum and VIL is 0.3 × VCC maximum. |
| 20 | VCC | power_in | Power supply, 3 V to 5.5 V recommended operating range. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
