STP16CP05TTR

STMicroelectronics · LED Drivers · TSSOP-24

STP16CP05TTR from STMicroelectronics, in a TSSOP-24. 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 Ground terminal. All internal logic and current-sink return path. IGND max 1600 mA.
2 SDI input Serial data input terminal to the 16-bit shift register. CMOS logic input (VIH ≥ 0.7 VDD).
3 CLK input Clock input terminal for the shift register. Data on SDI is shifted on the rising edge. Max clock frequency 30 MHz in cascade operation.
4 LE/DM1 input Latch enable input terminal. When high, transfers the shift register contents into the 16-bit data latch. Minimum pulse width 6 ns.
5 OUT0 output Constant current sink output 0. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
6 OUT1 output Constant current sink output 1. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
7 OUT2 output Constant current sink output 2. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
8 OUT3 output Constant current sink output 3. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
9 OUT4 output Constant current sink output 4. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
10 OUT5 output Constant current sink output 5. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
11 OUT6 output Constant current sink output 6. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
12 OUT7 output Constant current sink output 7. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
13 OUT8 output Constant current sink output 8. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
14 OUT9 output Constant current sink output 9. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
15 OUT10 output Constant current sink output 10. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
16 OUT11 output Constant current sink output 11. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
17 OUT12 output Constant current sink output 12. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
18 OUT13 output Constant current sink output 13. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
19 OUT14 output Constant current sink output 14. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
20 OUT15 output Constant current sink output 15. Programmable 5-100 mA via R-EXT, supports up to 20 V output driving.
21 OE/DM2 input Output enable input, active low. When low, the 16 output current sinks are enabled; when high, all outputs are turned off. Minimum pulse width 100 ns.
22 SDO output Serial data output. Tap of the last (16th) shift-register stage; connect to SDI of the next device for cascading. IOH = -1 mA, IOL = 1 mA.
23 R-EXT passive External resistor terminal for constant current programming. A resistor from R-EXT to GND sets the output current for all 16 sinks (200 Ω → ~100 mA, 1 kΩ → ~20 mA, 4.2 kΩ → ~5 mA).
24 VDD power_in Supply voltage terminal. Operating range 3.0 V to 5.5 V (absolute max 7 V). Decouple to GND close to the device.
