CAT4016HV6-GT2 from onsemi, in a TQFN-24-EP(4x4). 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 moves from SIN into the 16-bit shift register (up to 25 MHz). |
| 4 | LATCH | input | Latch input; the rising edge loads the 16-bit shift register into the output latch, the falling edge latches it, with an internal 180 kΩ typical pull-down. |
| 5 | LED1 | passive | LED channel 1 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 6 | LED2 | passive | LED channel 2 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 7 | LED3 | passive | LED channel 3 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 8 | LED4 | passive | LED channel 4 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 9 | LED5 | passive | LED channel 5 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 10 | LED6 | passive | LED channel 6 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 11 | LED7 | passive | LED channel 7 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 12 | LED8 | passive | LED channel 8 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 13 | LED9 | passive | LED channel 9 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 14 | LED10 | passive | LED channel 10 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 15 | LED11 | passive | LED channel 11 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 16 | LED12 | passive | LED channel 12 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 17 | LED13 | passive | LED channel 13 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 18 | LED14 | passive | LED channel 14 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 19 | LED15 | passive | LED channel 15 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 20 | LED16 | passive | LED channel 16 cathode current sink; the LED pin voltage must be above 0.4 V for correct operation. |
| 21 | BLANK | input | Enable/disable input for all channels; low enables LEDs per the latch, high turns all LEDs off, with an internal 180 kΩ typical pull-up. |
| 22 | SOUT | output | Serial data output of the 16-bit shift register, connected to SIN of the next device to cascade. |
| 23 | RSET | passive | LED current set pin; a resistor to ground sets each channel current to 50 times the RSET pin current, with the pin regulated to 1.2 V. |
| 24 | VDD | power_in | Positive supply pin for the entire device, 3.0 V to 5.5 V recommended, with a 1 µF ceramic capacitor close to the pin. |
| 25 | EP | power_in | Exposed pad (TAB, TQFN only); connect to GND on the PCB. |
