XD7219 from XINLUDA, in a DIP-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 | DIN | input | Serial-Data Input; data is loaded into the internal 16-bit shift register on CLK rising edge. |
| 2 | DIG 0 | output | Digit 0 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 3 | DIG 1 | output | Digit 1 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 4 | GND | power_in | Ground connection; both GND pins must be connected. |
| 5 | DIG 2 | output | Digit 2 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 6 | DIG 3 | output | Digit 3 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 7 | DIG 4 | output | Digit 4 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 8 | DIG 5 | output | Digit 5 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 9 | GND | power_in | Ground connection; both GND pins must be connected. |
| 10 | DIG 6 | output | Digit 6 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 11 | DIG 7 | output | Digit 7 drive line that sinks current from the display common cathode; pulled to V+ when turned off. |
| 12 | LOAD | input | Load-Data Input; the last 16 bits of serial data are latched on LOAD rising edge. |
| 13 | CLK | input | Serial-Clock Input; 10MHz maximum rate; data shifts into shift register on CLK rising edge and outputs on falling edge. |
| 14 | SEG A | output | Segment A drive line that sources current to the display; pulled to GND when turned off. |
| 15 | SEG B | output | Segment B drive line that sources current to the display; pulled to GND when turned off. |
| 16 | SEG C | output | Segment C drive line that sources current to the display; pulled to GND when turned off. |
| 17 | SEG D | output | Segment D drive line that sources current to the display; pulled to GND when turned off. |
| 18 | ISET | input | Current setting input; connect to V+ through a resistor (RSET) to set the peak segment current (nominally 100× the ISET pin current). |
| 19 | V+ | power_in | Positive Supply Voltage; connect to +5V nominal (operating range 4.0V to 5.5V per electrical characteristics on Page 3). |
| 20 | SEG E | output | Segment E drive line that sources current to the display; pulled to GND when turned off. |
| 21 | SEG F | output | Segment F drive line that sources current to the display; pulled to GND when turned off. |
| 22 | SEG G | output | Segment G drive line that sources current to the display; pulled to GND when turned off. |
| 23 | DP | output | Decimal Point drive line that sources current to the display; pulled to GND when turned off. |
| 24 | DOUT | output | Serial-Data Output; propagates input data from DIN 16.5 clock cycles later; used for daisy-chaining multiple devices; never high-impedance. |
