MAX7219CWG+ from Analog Devices Inc Maxim Integrated, in a SOIC-24-300mil. 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 loaded into the internal 16-bit shift register on CLK's rising edge. |
| 2 | DIG 0 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 3 | DIG 1 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 4 | GND | power_in | Ground; both GND pins (4 and 9) must be connected. |
| 5 | DIG 2 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 6 | DIG 3 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 7 | DIG 4 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 8 | DIG 5 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 9 | GND | power_in | Ground; both GND pins (4 and 9) must be connected. |
| 10 | DIG 6 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 11 | DIG 7 | output | Eight-digit drive line that sinks current from the display common cathode; MAX7219 pulls output to V+ when turned off. |
| 12 | LOAD | input | Load-Data Input; the last 16 bits of serial data are latched on LOAD's rising edge. |
| 13 | CLK | input | Serial-Clock Input, 10MHz maximum rate; data shifted into shift register on rising edge, clocked out DOUT on falling edge. |
| 14 | SEG A | output | Segment A drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 15 | SEG F | output | Segment F drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 16 | SEG B | output | Segment B drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 17 | SEG G | output | Segment G drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 18 | ISET | passive | Connect to V+ through resistor RSET to set the peak segment current (minimum RSET value 9.53kΩ, current nominally 100× ISET). |
| 19 | V+ | power_in | Positive Supply Voltage; connect to +5V, operating range 4.0 to 5.5V. |
| 20 | SEG E | output | Segment E drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 21 | SEG C | output | Segment C drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 22 | SEG DP | output | Decimal Point drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 23 | SEG D | output | Segment D drive that sources current to the display; when segment driver is turned off, pulled to GND. |
| 24 | DOUT | output | Serial-Data Output; data from DIN is valid at DOUT 16.5 clock cycles later, used to daisy-chain devices, never high-impedance. |
