STP16CPS05TTR 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 / return terminal. Also serves as return for the sink output currents; absolute max IGND = 1600 mA.
2 SDI input Serial data input into the 16-bit shift register. CMOS logic input (VIH = 0.7 VDD, VIL = 0.3 VDD). Data is clocked in on the rising edge of CLK.
3 CLK input Shift-register clock input. Rising edge shifts SDI into the shift register and moves data toward SDO. Max fCLK = 30 MHz (cascade), 50 MHz absolute.
4 LE input Latch enable input. Level-sensitive: when high, the 16-bit D-type storage latch transparently follows the shift register; when low, latch holds the previous data.
5 OUT0 output Constant-current sink output channel 0. Programmable 5-100 mA via R-EXT; can withstand up to 20 V. Open-drain N-channel current-regulated sink to GND.
6 OUT1 output Constant-current sink output channel 1. Programmable 5-100 mA via R-EXT; 20 V output capability.
7 OUT2 output Constant-current sink output channel 2. Programmable 5-100 mA via R-EXT; 20 V output capability.
8 OUT3 output Constant-current sink output channel 3. Programmable 5-100 mA via R-EXT; 20 V output capability.
9 OUT4 output Constant-current sink output channel 4. Programmable 5-100 mA via R-EXT; 20 V output capability.
10 OUT5 output Constant-current sink output channel 5. Programmable 5-100 mA via R-EXT; 20 V output capability.
11 OUT6 output Constant-current sink output channel 6. Programmable 5-100 mA via R-EXT; 20 V output capability.
12 OUT7 output Constant-current sink output channel 7. Programmable 5-100 mA via R-EXT; 20 V output capability.
13 OUT8 output Constant-current sink output channel 8. Programmable 5-100 mA via R-EXT; 20 V output capability.
14 OUT9 output Constant-current sink output channel 9. Programmable 5-100 mA via R-EXT; 20 V output capability.
15 OUT10 output Constant-current sink output channel 10. Programmable 5-100 mA via R-EXT; 20 V output capability.
16 OUT11 output Constant-current sink output channel 11. Programmable 5-100 mA via R-EXT; 20 V output capability.
17 OUT12 output Constant-current sink output channel 12. Programmable 5-100 mA via R-EXT; 20 V output capability.
18 OUT13 output Constant-current sink output channel 13. Programmable 5-100 mA via R-EXT; 20 V output capability.
19 OUT14 output Constant-current sink output channel 14. Programmable 5-100 mA via R-EXT; 20 V output capability.
20 OUT15 output Constant-current sink output channel 15 (last output). Programmable 5-100 mA via R-EXT; 20 V output capability.
21 OE input Output enable, active low. When low, OUT0-OUT15 follow the latched data; when high, all sixteen outputs are forced OFF. Also serves as DM2 for detection feature.
22 SDO output Serial data output from bit 16 of the shift register, for cascading multiple STP16CPS05 devices. CMOS push-pull output rated ±1 mA (VOL ≤ 0.4 V @ 1 mA, VOH ≥ VDD-0.4 V @ -1 mA).
23 R-EXT passive Reference-current programming pin. Connect an external resistor from R-EXT to GND to set the per-channel output current (e.g. 976 Ω → 20 mA, 389 Ω → 50 mA, 215 Ω → 90 mA per Table 11).
24 VDD power_in Positive supply voltage. Recommended operating range 3.0 V to 5.5 V (absolute max 7 V). Bypass locally with a decoupling capacitor.
