Triple 3-input NAND gate for wide-temperature logic
The onsemi MM74HC10MX is a triple 3-input NAND gate from the 74HC family, built in high-speed CMOS. It operates from 2V to 6V, making it a drop-in for both 3.3V and 5V logic domains. The three independent gates each have three inputs, and the part is rated over the full military temperature range of -55°C to 125°C — suited for avionics, satellite, downhole instrumentation, or any environment where the board sees extreme cold or heat.
16 ns propagation delay — timing margin for fast buses
Maximum propagation delay is 16 ns at 6V with a 50 pF load. Quiescent current is 1 µA max.
Active lifecycle — no obsolescence risk on this BOM line
The MM74HC10MX carries an Active product status. That means onsemi is still manufacturing it, no last-time-buy notice has been issued, and you can qualify it into a new design without worrying about a forced respin in the next few years.
