MAX7219CWG Description

Short technical summary and product information.

The MAX7219CWG is a compact, serial input/output common-cathode display driver designed to interface microprocessors with 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. It includes on-chip BCD code-B decoding, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM.

 

Key electrical specifications include an input voltage range of 4V to 5.5V, an output current of up to 330 mA, and a 10 MHz serial interface. The device supports both analog and digital brightness control, a low-power shutdown mode of 150μA, and allows for individual LED segment control. It is designed to drive common-cathode LED displays.

 

Packaged in a 24-SOIC surface-mount case, the MAX7219CWG operates within a temperature range of 0°C to 70°C. Its features make it suitable for applications such as industrial controllers, panel meters, and LED matrix displays.
