TLC59291RGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 | Data latch pin; rising edge latches 16-bit shift register data into output on/off data latch. |
| 2 | OUT0 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 3 | OUT1 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 4 | OUT2 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 5 | OUT3 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 6 | OUT4 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 7 | OUT5 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 8 | OUT6 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 9 | OUT7 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 10 | OUT8 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 11 | OUT9 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 12 | OUT10 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 13 | OUT11 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 14 | OUT12 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 15 | OUT13 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 16 | OUT14 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 17 | OUT15 | output | Constant-current sink output; operating current 1-40 mA at VCC ≤ 3.6V or 1-50 mA at VCC > 3.6V; maximum output voltage 11V. |
| 18 | BLANK | input | Configurable blank/output enable pin; operates as SOUT select or output enable depending on FC9(BLANK Mode) bit; forces all OUTx off when high in enable mode. |
| 19 | SOUT | output | Serial data output from 16-bit shift register; data clocked out at SCLK rising edge; bit 7 or bit 15 selected by BLANK pin. |
| 20 | IREF | input | Current reference input; external resistor (1.32 kΩ to 66 kΩ) connected between IREF and GND sets maximum output current; direct GND connection forces all outputs off. |
| 21 | VCC | power_in | Power supply input; operating voltage range 3V to 5.5V. |
| 22 | GND | power_in | Ground reference. |
| 23 | SIN | input | Serial data input for 16-bit shift register; '1' written to LSB on SCLK rising edge when SIN is high. |
| 24 | SCLK | input | Serial clock input; data shifted at rising edge; maximum frequency 33 MHz. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
