CAT4016Y-T2

onsemi · LED Drivers · TSSOP-24

CAT4016Y-T2 from onsemi, in a TSSOP-24. 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 reference pin that must be connected to the ground plane on the PCB.
2 SIN input Serial data input; data is loaded into the internal register on each rising edge of CLK.
3 CLK input Serial clock input; on each rising edge data is transferred from SIN to the internal 16-bit shift register, up to 25 MHz.
4 LATCH input Latch data input; the rising edge loads the 16-bit shift register into the output register latch and the falling edge latches it, with an internal pull-down of 100 to 300 kΩ.
5 LED1 output LED channel 1 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
6 LED2 output LED channel 2 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
7 LED3 output LED channel 3 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
8 LED4 output LED channel 4 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
9 LED5 output LED channel 5 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
10 LED6 output LED channel 6 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
11 LED7 output LED channel 7 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
12 LED8 output LED channel 8 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
13 LED9 output LED channel 9 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
14 LED10 output LED channel 10 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
15 LED11 output LED channel 11 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
16 LED12 output LED channel 12 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
17 LED13 output LED channel 13 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
18 LED14 output LED channel 14 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
19 LED15 output LED channel 15 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
20 LED16 output LED channel 16 cathode current sink with current equal to 50 times the RSET pin current; the pin voltage must be above 0.4 V.
21 BLANK input LED enable/disable input: low enables LEDs per the latch register, high turns all LEDs off while preserving latch data, with an internal pull-up of 100 to 300 kΩ.
22 SOUT output Serial data output of the 16-bit shift register, connected to SIN of the next device to cascade devices.
23 RSET passive LED current setting pin with a resistor to ground; each channel current is 50 times the current pulled out of the pin, which is regulated to 1.2 V.
24 VDD power_in Positive supply pin for the entire device, 3.0 to 5.5 V, with a small 1 µF ceramic capacitor recommended close to the pin.
