TLC59281DBQR

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

TLC59281DBQR from Texas Instruments, in a SSOP-24-150mil. 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 GND power_in Power ground.
2 SIN input Serial data input for on/off control; when high, data '1' are written into LSB of on/off control shift register at rising edge of SCLK.
3 SCLK input Serial data shift clock with Schmitt buffer input; shifts all data in on/off control shift register toward MSB by 1-bit at rising edge; rising edge allowed 100 ns after LAT rising edge.
4 LAT input Edge-triggered latch; on/off control data transferred from shift register to latch at rising edge; must toggle only once after shift data update.
5 OUT0 output Constant-current sink output; each output can be tied with others to increase current; output voltage range from -0.3 V to +18 V.
6 OUT1 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
7 OUT2 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
8 OUT3 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
9 OUT4 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
10 OUT5 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
11 OUT6 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
12 OUT7 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
13 OUT8 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
14 OUT9 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
15 OUT10 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
16 OUT11 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
17 OUT12 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
18 OUT13 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
19 OUT14 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
20 OUT15 output Constant-current sink output; output voltage range from -0.3 V to +18 V.
21 BLANK input Blank all outputs; when high, all constant-current outputs (OUT0-OUT15) forced off; when low, outputs controlled by on/off control latch data.
22 SOUT output Serial data output connected to MSB of on/off data shift register; data changes at rising edge of SCLK.
23 IREF bidirectional Constant-current value setting; OUT0-OUT15 sink constant-current set by connection of external resistor between IREF and GND; reference voltage VIREF = 1.20 V typical.
24 VCC power_in Power-supply voltage; operating range 3.0 V to 5.5 V.
