What this 4:10 decoder brings to the bench
It's the classic CMOS decoder you reach for when you need to drive a seven-segment display, route a control signal, or demultiplex an address bus in a system that runs on a wide supply rail. The part lives in a 16-SOIC package, so it's a drop-in for any surface-mount board that needs a clean 4:10 decode without the overhead of a programmable logic device.
Supply range and temperature — the real-world envelope
The CD4028BMT operates from 3V to 18V single supply, which covers everything from a 3.3V logic rail up to a 12V or 15V industrial bus. That wide compliance means you can use the same decoder across different voltage domains without a level shifter, as long as the input thresholds align. The 6.8mA output drive per pin is modest; it's enough to light an LED or drive a CMOS load, but don't plan to fan out to a dozen TTL inputs without buffering.
Lifecycle and sourcing posture
It's ROHS3 compliant, which clears it for EU and RoHS-restricted markets.
