TLC59482DBQR

Texas Instruments · LED Drivers · SSOP-24-150mil

TLC59482DBQR 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 Power ground for the device, and the thermal pad must be connected to GND through the PCB pattern because it is not internally connected to GND.
2 SIN input Serial data input for the 16-bit common shift register, with data shifted into the LSB on each SCLK rising edge.
3 SCLK input Serial data shift clock; data on SIN are shifted into the LSB of the 16-bit common shift register on each rising edge and shifted toward the MSB.
4 LAT input Latch input; the LAT falling edge latches data from the 16-bit common shift register into the GS data latch, and the pin is internally pulled down to GND with a 500-kΩ (typ) resistor.
5 OUT0 output Constant-current sink output channel 0; outputs can be paralleled for more current and each output can see a different voltage.
6 OUT1 output Constant-current sink output channel 1; outputs can be paralleled for more current and each output can see a different voltage.
7 OUT2 output Constant-current sink output channel 2; outputs can be paralleled for more current and each output can see a different voltage.
8 OUT3 output Constant-current sink output channel 3; outputs can be paralleled for more current and each output can see a different voltage.
9 OUT4 output Constant-current sink output channel 4; outputs can be paralleled for more current and each output can see a different voltage.
10 OUT5 output Constant-current sink output channel 5; outputs can be paralleled for more current and each output can see a different voltage.
11 OUT6 output Constant-current sink output channel 6; outputs can be paralleled for more current and each output can see a different voltage.
12 OUT7 output Constant-current sink output channel 7; outputs can be paralleled for more current and each output can see a different voltage.
13 OUT8 output Constant-current sink output channel 8; outputs can be paralleled for more current and each output can see a different voltage.
14 OUT9 output Constant-current sink output channel 9; outputs can be paralleled for more current and each output can see a different voltage.
15 OUT10 output Constant-current sink output channel 10; outputs can be paralleled for more current and each output can see a different voltage.
16 OUT11 output Constant-current sink output channel 11; outputs can be paralleled for more current and each output can see a different voltage.
17 OUT12 output Constant-current sink output channel 12; outputs can be paralleled for more current and each output can see a different voltage.
18 OUT13 output Constant-current sink output channel 13; outputs can be paralleled for more current and each output can see a different voltage.
19 OUT14 output Constant-current sink output channel 14; outputs can be paralleled for more current and each output can see a different voltage.
20 OUT15 output Constant-current sink output channel 15; outputs can be paralleled for more current and each output can see a different voltage.
21 GSCLK input Grayscale PWM reference clock; each rising edge increments the GS counter, and the TMGRST or LATGS commands (with TMRSTEN or XRFRESH set to 1) force all outputs off and reset the GS counter to 0.
22 SOUT output Serial data output of the 16-bit common shift register, clocked out on the SCLK rising edge; function data latch contents can be read here during the READFC command.
23 IREF bidirectional Reference current terminal; a resistor connected from IREF to GND sets the maximum current for all constant-current outputs.
24 VCC power_in Power-supply voltage input for the device.
