Display Drivers datasheet and documents for MAX7219CWG+G126
Display Drivers Overview
The MAX7219CWG+ is a compact, serial input/output common-cathode display driver manufactured by Analog Devices Inc./Maxim Integrated. It interfaces microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. The device integrates a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM for data storage. A single external resistor sets the segment current for all LEDs. It operates within a supply voltage range of 4V to 5.5V, with a maximum supply current of 330mA. The unit is housed in a 24-SOIC package.
Display Drivers Feature Summary
- Serial interface compatible with standard microprocessor protocols
- Integrated BCD decoder and multiplex scan circuitry
- On-chip 8x8 static RAM for digit storage
- Single-resistor programmable segment current control
Display Drivers Applications
- 7-segment numeric LED displays
- Bar-graph displays
- LED matrix displays
Display Drivers Procurement Notes
Verify the specific suffix 'G126' against official manufacturer documentation to confirm it denotes a valid tape-and-reel variant or specific packaging configuration distinct from the standard MAX7219CWG+. Ensure the component matches the SOIC-24 package and RoHS compliance standards required for your assembly process.
Display Drivers Selection Notes
Select this component when interfacing microcontrollers with high-digit-count LED displays requiring minimal pin usage. It is suitable for applications needing integrated decoding and brightness control without external logic gates. Consider the MAX7221 if slew-rate limited drivers are necessary to reduce electromagnetic interference.
Display Drivers Part Context
This part belongs to the MAX7219 family of display drivers, widely used in industrial controllers and panel meters. It serves as a cost-effective solution for managing multiple LED segments through a simple serial connection, reducing PCB trace count and microprocessor I/O port requirements.
Display Drivers Replacement Considerations
The MAX7221 is a direct functional substitute offering similar drive capabilities with added slew-rate limiting for EMI reduction. Verify pin compatibility and software register mapping before substitution.
