Texas Instruments · Integrated Circuits (ICs) · SSOP-24_3.9x8.7mm_P0.635mm

TLC5925IDBQR from Texas Instruments, in a SSOP-24_3.9x8.7mm_P0.635mm. 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 for control logic and current sink; all LED current passes through the device into this ground node, so it needs a strong connection to the board ground.
2 SDI input Serial-data input to the 16-bit shift register, with VIH of 0.7 × VDD minimum and VIL of 0.3 × VDD maximum.
3 CLK input Clock input that shifts data on the rising edge, with a maximum clock frequency of 30 MHz in cascade operation.
4 LE input Data strobe that transfers serial data to the latch while high and latches the data when it goes low, with an internal pull-down resistor of 500 kΩ.
5 OUT0 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
6 OUT1 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
7 OUT2 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
8 OUT3 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
9 OUT4 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
10 OUT5 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
11 OUT6 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
12 OUT7 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
13 OUT8 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
14 OUT9 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
15 OUT10 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
16 OUT11 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
17 OUT12 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
18 OUT13 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
19 OUT14 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
20 OUT15 output Constant-current sink output rated for up to 17 V at the output port and up to 45 mA at VO ≥ 1 V.
21 OE input Output enable that turns the output drivers on when low and blanks all outputs when high, with an internal pullup resistor of 500 kΩ.
22 SDO output Serial-data output to the SDI of the next driver IC or to the microcontroller, with IOH limited to -1 mA and IOL limited to 1 mA.
23 R-EXT input Input for an external resistor Rext that sets the output current, where IOUT,target = (1.21 V / Rext) × 18.
24 VDD power_in Supply voltage input with a recommended range of 3 V to 5.5 V and an absolute maximum of 7 V.
