**Texas Instruments** · LED Drivers · TSSOP-16

TLC5917IPW from Texas Instruments, in a TSSOP-16. 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 | GND | power_in | Ground for control logic and current sink |
| 2 | SDI | input | Serial-data input to shift register |
| 3 | CLK | input | Clock input for data shift on rising edge |
| 4 | LE(ED1) | input | Data strobe input with internal pulldown; serial data transferred to latch when high, latched when low; control signal for Error Detection and Current Adjust Modes |
| 5 | OUT0 | output | Constant-current output |
| 6 | OUT1 | output | Constant-current output |
| 7 | OUT2 | output | Constant-current output |
| 8 | OUT3 | output | Constant-current output |
| 9 | OUT4 | output | Constant-current output |
| 10 | OUT5 | output | Constant-current output |
| 11 | OUT6 | output | Constant-current output |
| 12 | OUT7 | output | Constant-current output |
| 13 | OE(ED2) | input | Output enable with internal pullup; active low enables drivers, high blanks all drivers; control signal for Error Detection and Current Adjust Modes |
| 14 | SDO | output | Serial-data output to next driver IC or microcontroller |
| 15 | R-EXT | input | External resistor connected to ground to set constant-current output level for all channels |
| 16 | VDD | power_in | Supply voltage; recommended operating range 3 to 5.5 V |
