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

TLC6C598PWR 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 | VCC | power_in | Power supply pin for the device, recommended supply voltage range 3 V to 5.5 V. |
| 2 | SER_IN | input | Serial data input; data on SER_IN loads into the internal register on each rising edge of SRCK. |
| 3 | DRAIN0 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 4 | DRAIN1 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 5 | DRAIN2 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 6 | DRAIN3 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 7 | CLR | input | Shift register clear, active-low; storage register transfers data to output buffer when CLR is high; driving CLR low clears all registers in the device. |
| 8 | G | input | Output enable, active-low; having G low enables all drain channels according to output-latch register content; when G is high, all channels are off. |
| 9 | SER_OUT | output | Serial data output of the 8-bit serial shift register; purpose is to cascade several devices on the serial bus. |
| 10 | RCK | input | Register clock input; data in each shift register stage transfers to the storage register at the rising edge of RCK. |
| 11 | DRAIN4 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 12 | DRAIN5 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 13 | DRAIN6 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 14 | DRAIN7 | output | Open-drain output LED current-sink channel with 50-mA continuous current or 200-mA PWM current capability at 5 V, 40-V rated, connect to LED cathode. |
| 15 | SRCK | input | Serial clock input; on each rising SRCK edge, data transfers from SER_IN to the internal serial shift registers. |
| 16 | GND | power_in | Power ground, the ground reference pin for the device; must connect to the ground plane on the PCB. |
