XD7219

XINLUDA · Digital Tube Drivers · DIP-24

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.
