TLC6C598QPWRQ1 from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Logic supply pin, 3 V to 5.5 V (absolute max 8 V). Add a 0.1-uF ceramic bypass capacitor close to the pin. |
| 2 | SER_IN | input | Serial data input. Data on SER_IN is loaded into the internal shift register on each rising edge of SRCK. VIH = 2.4 V min, VIL = 0.7 V max; setup/hold 15 ns. |
| 3 | DRAIN0 | output | Open-drain low-side DMOS output, bit 0 of the storage register. 40-V drain-source rating, up to 50 mA continuous sink at VCC = 5 V. Connect to LED cathode with a series resistor. |
| 4 | DRAIN1 | output | Open-drain low-side DMOS output, bit 1 of the storage register. 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 5 | DRAIN2 | output | Open-drain low-side DMOS output, bit 2 of the storage register. 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 6 | DRAIN3 | output | Open-drain low-side DMOS output, bit 3 of the storage register. 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 7 | CLR | input | Shift-register clear, active-low. Driving CLR low clears all registers in the device; the storage register transfers data to the output buffer when CLR is high. TI recommends asserting CLR during power-up or initialization. |
| 8 | G | input | Output enable, active-low. When G is low, the storage-register data is transparent to the output buffers and enabled channels can sink current; when G is high, all output buffers are forced low and all drain outputs are off. Can be used as a global PWM-dimming input. |
| 9 | SER_OUT | output | Serial data output of the 8-bit shift register, intended to feed the SER_IN of the next device in a cascaded chain. Data is clocked out on the falling edge of SRCK to provide extra hold margin between cascaded devices. |
| 10 | RCK | input | Register (latch) clock. On the rising edge of RCK, the data in each shift-register stage is transferred into the storage register and becomes visible at the outputs (when G is low). |
| 11 | DRAIN4 | output | Open-drain low-side DMOS output, bit 4 of the storage register. 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 12 | DRAIN5 | output | Open-drain low-side DMOS output, bit 5 of the storage register. 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 13 | DRAIN6 | output | Open-drain low-side DMOS output, bit 6 of the storage register. 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 14 | DRAIN7 | output | Open-drain low-side DMOS output, bit 7 of the storage register (MSB). 40-V, 50-mA continuous-sink LED current-sink channel; connect to LED cathode. |
| 15 | SRCK | input | Serial shift-register clock input. On each rising edge of SRCK, data transfers from SER_IN into the internal shift register; SER_OUT updates on the falling edge. Max 10 MHz (CL = 30 pF, ID = 20 mA); min high/low pulse 30 ns. |
| 16 | GND | power_in | Power/ground reference for the device. Connect to the board ground plane; maximize copper and use thermal vias under the package for heat dissipation. |
