What are the key features of HCC4555BDG?
- Radiation-hardened CMOS 4000B-series logic operates across 3V to 18V supply range, suitable for harsh aerospace and defense environments
- Dual 2-line to 4-line decoder with true-output polarity decodes 2-bit binary addresses to 4 active-high output lines per channel
- 16-pin ceramic DIP package with glass-sealed hermetic construction provides reliability in high-temperature and radiation-exposed installations
What is HCC4555BDG used for?
The HCC4555BDG is targeted at space, avionics, and military-grade digital systems where radiation tolerance and wide supply-voltage flexibility are mandatory. Its dual decoder structure allows two independent address-to-line demultiplexer functions in a single package, simplifying memory bank selection and peripheral address decoding on rad-hard bus designs. The hermetic ceramic DIP package survives temperature extremes and cumulative radiation doses that disqualify standard plastic CMOS packages.

Frequently Asked Questions
Over what supply voltage range does HCC4555BDG operate, and what logic levels does it accept at 5V?
HCC4555BDG is specified for a supply range of 3V to 18V in the CMOS 4000B series. At 5V VDD, the logic high threshold is typically 3.5V and logic low is below 1.5V, conforming to standard CMOS noise-margin requirements. This wide voltage tolerance allows it to interface with both 5V TTL-level logic and up to 15V industrial control signals without level shifters.
What does 'rad-hard' mean for HCC4555BDG, and in which satellite or avionics applications is it qualified?
Radiation-hardened variants like HCC4555BDG are manufactured with process modifications that minimize single-event upsets (SEU) and total ionizing dose (TID) effects, typically rated for at least 100 krad(Si) TID tolerance. This qualification makes it suitable for LEO and GEO satellite on-board computers, launch vehicle avionics, and deep-space instrument buses where COTS plastic logic would fail within months of orbital exposure.
How do the 2 decoder channels inside HCC4555BDG reduce component count in a memory address decoder?
Each of the 2 independent channels inside HCC4555BDG decodes a 2-bit binary input (A, B) plus an active-low enable into 4 individually driven active-high output lines. Two channels in one 16-pin package replace 2 discrete decoder ICs, saving board space and solder joints in constrained avionics modules. Together they can select up to 8 independent memory or peripheral bank-select lines.
