TLC59731DR

Texas Instruments · LED Drivers · SOIC-8

TLC59731DR from Texas Instruments, in a SOIC-8. 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 OUT0 output Sink driver output 0 (up to 50 mA, max 21 V); multiple outputs can be paralleled to increase sink current and each output can have a different voltage applied.
2 OUT1 output Sink driver output 1 (up to 50 mA, max 21 V); multiple outputs can be paralleled to increase sink current and each output can have a different voltage applied.
3 OUT2 output Sink driver output 2 (up to 50 mA, max 21 V); multiple outputs can be paralleled to increase sink current and each output can have a different voltage applied.
4 GND power_in Power ground.
5 SDO output Serial data output, rated for 2 mA high/low output current and up to 7.0 V absolute maximum.
6 SDI input Serial data input, internally pulled down to GND with a 1-MΩ (typical) resistor, with data rate 20 to 600 kHz.
7 TEST passive TI internal test terminal that must be connected to GND or left open.
8 VCC power_in Power-supply voltage, 3.0 V to 5.5 V without internal shunt regulator mode (up to 6 V in shunt regulator mode, 20 mA max shunt current).
