TLC5927IDBQR from Texas Instruments, in a SSOP-24-150mil. 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 pin for the control logic and the constant-current sinks. |
| 2 | SDI | input | Serial-data input to the 16-bit shift register; Schmitt-trigger input with VIH of 0.7×VDD min and VIL of 0.3×VDD max. |
| 3 | CLK | input | Clock input for data shift on the rising edge, rated up to 30 MHz maximum clock frequency. |
| 4 | LE(ED1) | input | Data strobe: serial data transfers to the latches while high and is latched on the falling edge; it also serves as a control input for error-detection and current-adjust modes, and has an internal pulldown. |
| 5 | OUT0 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 6 | OUT1 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 7 | OUT2 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 8 | OUT3 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 9 | OUT4 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 10 | OUT5 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 11 | OUT6 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 12 | OUT7 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 13 | OUT8 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 14 | OUT9 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 15 | OUT10 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 16 | OUT11 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 17 | OUT12 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 18 | OUT13 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 19 | OUT14 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 20 | OUT15 | output | Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current. |
| 21 | OE(ED2) | input | Active-low output enable: when low the output drivers are enabled, when high all outputs are blanked; it also serves as a control input for error-detection and current-adjust modes, and has an internal pullup. |
| 22 | SDO | output | Serial-data output to the SDI of the next driver IC or to the microcontroller, with IOH of -1 mA and IOL of 1 mA maximum. |
| 23 | R-EXT | input | Input pin for the external resistor that sets the output current of all channels (5 mA to 120 mA range). |
| 24 | VDD | power_in | Supply voltage pin, 3 V to 5.5 V recommended operating range. |
