Four-digit LED decoder/driver in 44-PLCC
The ICM7212MIQH is a four-digit LED display decoder/driver from Maxim Integrated, handling BCD input and driving a 7-segment common-cathode display directly. It's the IC you reach for when a panel needs a clean numeric readout without multiplexing overhead — the internal latches and segment drivers do the work, so the host controller just sends BCD data and a digit-select strobe. Supply range is 4 V to 6 V, drawing 200 mA typical — the current budget covers the driver's own consumption plus the LED segment current, so the board's 5 V rail needs to hold regulation under that load.
Package and temperature grade
Rated for -20°C to +85°C operation — this is the industrial temperature band. It lives comfortably in a control cabinet or test-equipment chassis that sees seasonal swings, but not under-hood or outdoor direct-sun exposure without enclosure derating.
