TLC5927IDBQR

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

TLC5927IDBQR 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 Ground pin for the control logic and the constant-current sinks.
2 SDI input Serial-data input to the 16-bit shift register; Schmitt-trigger input with VIH of 0.7×VDD min and VIL of 0.3×VDD max.
3 CLK input Clock input for data shift on the rising edge, rated up to 30 MHz maximum clock frequency.
4 LE(ED1) input Data strobe: serial data transfers to the latches while high and is latched on the falling edge; it also serves as a control input for error-detection and current-adjust modes, and has an internal pulldown.
5 OUT0 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
6 OUT1 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
7 OUT2 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
8 OUT3 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
9 OUT4 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
10 OUT5 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
11 OUT6 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
12 OUT7 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
13 OUT8 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
14 OUT9 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
15 OUT10 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
16 OUT11 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
17 OUT12 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
18 OUT13 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
19 OUT14 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
20 OUT15 output Constant-current sink output, rated up to 17 V at the output port with up to 120 mA sink current.
21 OE(ED2) input Active-low output enable: when low the output drivers are enabled, when high all outputs are blanked; it also serves as a control input for error-detection and current-adjust modes, and has an internal pullup.
22 SDO output Serial-data output to the SDI of the next driver IC or to the microcontroller, with IOH of -1 mA and IOL of 1 mA maximum.
23 R-EXT input Input pin for the external resistor that sets the output current of all channels (5 mA to 120 mA range).
24 VDD power_in Supply voltage pin, 3 V to 5.5 V recommended operating range.
