4-digit 7-segment LED driver with BCD interface
The ICM7212AMIPL+ from Analog Devices is a 4-digit, 7-segment LED display driver that accepts a BCD input and drives common-cathode LED displays directly — no external current-limiting resistors needed for the segment outputs. It operates from a 4V to 6V supply and draws 200 mA typical, enough to sink the segment current for four digits without additional drive transistors. The 40-pin DIP package (0.600" body width) is a through-hole footprint that suits prototyping, legacy panel-meter retrofits, and industrial control-panel displays where surface-mount is not preferred.
Rated for a 4V to 6V supply rail — this is a tight window that matches a regulated 5V logic supply. The 200 mA supply current is the total chip draw with all segments lit; the actual LED current per segment is set by an external resistor on the reference pin. The -20°C to 85°C operating range covers industrial control cabinets and lab equipment but does not extend to automotive under-hood or extended outdoor exposure without thermal management.
Package and board-fit note
Housed in a 40-lead PDIP (0.600" row spacing) — the wide body requires a DIP socket or through-hole solder pads on 2.54 mm pitch. The 15.24 mm row spacing is standard for wide-body DIPs; verify the footprint matches the target PCB layout before committing the BOM line.
