Frequently Asked Questions
How many LED segments can MM5484N drive and what interface does it use?
MM5484N drives 16 segments per device using a serial data interface, eliminating the need for a wide parallel bus. Its common-anode configuration allows direct sourcing of LED current without external transistors. Multiple MM5484N devices can be daisy-chained via the serial line to drive larger 22-pin DIP-based displays up to hundreds of segments.
For a 5 V industrial front-panel display, what voltage and logic levels does MM5484N support?
MM5484N operates with standard TTL-compatible input logic levels at a 5 V supply, making it directly compatible with most 5 V microcontrollers and CPLDs. Its segment output can sink sufficient current to illuminate LEDs in a common-anode configuration, typically up to 20 mA per segment. This suits 5 V industrial panel designs without additional level-shifting circuits.
When is MM5484N a practical through-hole alternative to surface-mount LED drivers for prototyping?
MM5484N's 22-pin DIP package makes it ideal for breadboard prototyping and through-hole PCB designs where SMD rework is impractical. Unlike SOIC or QFN display drivers, the 0.1-inch pitch DIP enables manual soldering and quick replacement. For low-volume instrumentation or legacy industrial equipment where 22-pin DIP footprints already exist, MM5484N avoids costly PCB redesigns.
Does MM5484N support multiplexed displays, and how does that affect segment count per device?
MM5484N does not support multiplexed display mode; it directly drives all 16 segments simultaneously. This simplifies firmware since no time-multiplexing scan routine is needed, but it means each digit or character requires a dedicated MM5484N. For an 8-character alphanumeric display, 8 devices would be chained serially, providing 128 segments total at the cost of higher LED current consumption.
