- Hermetic ceramic metal-sealed DIP-14 package ensures moisture-free long-term storage for space mission lifetime-buy procurement
What is HCC4066BDG used for?
The HCC4066BDG is designed for analog signal routing and multiplexing in radiation-hardened spacecraft, satellite payload electronics, and defense avionics where single-event latchup immunity is mandatory. Its 4 independent bilateral switches allow designers to switch analog signals bidirectionally on the same channel without additional buffering. The wide 3 V to 18 V supply compatibility enables it to interface with both legacy 5 V TTL-level control logic and modern 3.3 V FPGA output drivers.

Frequently Asked Questions
How many independent switch channels does the HCC4066BDG provide, and what signal types can they switch?
The HCC4066BDG contains 4 independent SPST bilateral channels, each capable of switching analog or digital signals bidirectionally. The on-resistance is typically around 80 ohms at 5 V supply, and each channel can handle analog signals from 0 V to VDD, making it suitable for multiplexing sensor signals, audio, or low-speed data buses in radiation-hardened avionics.
What radiation tolerance makes the HCC4066BDG preferable to commercial CMOS switches in satellite designs?
The HCC4066BDG is qualified for total ionizing dose levels exceeding 100 krad(Si) and is immune to single-event latchup, whereas commercial CMOS bilateral switches typically fail or latch up after 10 krad(Si) or less in a geosynchronous orbit proton environment. This qualification removes the need for current-limiting latchup protection circuitry that commercial designs require.
What procurement advantage does the ceramic DIP-14 package offer for long-duration space programs?
The hermetic ceramic metal-sealed DIP-14 package of the HCC4066BDG passes MIL-STD-883 gross and fine leak tests, ensuring the internal die remains in a controlled atmosphere for over 20 years of storage. This allows space program procurement managers to execute lifetime buys at program start without re-qualification risk, a critical factor for missions with 15-year development timelines and no opportunity for in-orbit repair.
