Product details

LED driver for 8-digit multiplexed displays

The MAX7221ENG+ from Analog Devices is a serial-interfaced LED display driver that handles up to 8 digits of 7-segment displays with decimal point. It uses a 4-wire serial interface.

Supply current and thermal margin

The 330 mA supply current is the total chip draw with all segments lit at full drive. The -40°C to 85°C operating range covers industrial environments.

Sourcing and availability

We source the MAX7221ENG+ through independent distribution channels. This part is quoted to order with no minimum commitment.

Frequently asked questions

Does MAX7221ENG+ have the same pinout as MAX7219?

Yes, the MAX7221ENG+ is pin-compatible with the MAX7219. Both use the same 24-DIP footprint, so you can swap them without board layout changes. The key difference is that the MAX7221 includes an additional 8x8 static RAM and a more flexible serial interface that supports daisy-chaining multiple devices.

Can MAX7221ENG+ drive common cathode or common anode LEDs?

The MAX7221ENG+ is designed for common-cathode LED displays. The segment drivers source current, and the digit drivers sink current. Common-anode displays require an external transistor array or a different driver part.
