Key Features
- Radiation-hardened CMOS 4000B logic for reliable operation in space and nuclear environments with high total ionizing dose tolerance
- 4-bit unidirectional bus driver with dual-function enable-low control supports wide supply voltage range typical of HV CMOS 4000 series up to 18 V
- Ceramic DIL16 flat-pack (JESD-30 R-CDIP-T16) package provides hermetic sealing for long-term reliability in harsh aerospace and military applications
Applications
The HCC4503BDG is engineered for safety-critical and space-qualified electronics where standard plastic-packaged logic devices are not acceptable due to radiation or environmental exposure. Its radiation-hardened CMOS process and hermetic ceramic package make it suitable for satellite subsystems, nuclear instrumentation, and avionics bus interfaces requiring operation across wide supply voltages from 3 V to 18 V. The 4-bit bus driver configuration with active-low enable is commonly deployed in data bus isolation and signal buffering within fault-tolerant computing architectures.

Frequently Asked Questions
What voltage range and logic family does the HCC4503BDG belong to?
The HCC4503BDG is part of the CMOS 4000B logic family, which supports a wide supply voltage range from 3 V to 18 V, making it compatible with both 5 V and 12 V system rails. This wide range is a key advantage over standard TTL logic when interfacing mixed-voltage subsystems in aerospace or industrial controllers.
How does the radiation-hardened design of HCC4503BDG compare to standard CMOS 4000 series bus drivers?
The HCC4503BDG is fabricated on a rad-hard CMOS process that withstands high total ionizing dose (TID) levels, whereas standard CD4503B devices are not qualified for such environments. The ceramic DIL16 flat-pack hermetic package provides additional protection against moisture and outgassing, extending functional lifetime beyond 15 years in low-earth orbit or nuclear plant control rooms.
Which procurement lead time and packaging options should engineers expect for HCC4503BDG in space programs?
The HCC4503BDG is a ceramic hermetic device supplied in a DIL16 flat-pack (R-CDIP-T16) package, typically requiring longer procurement lead times of 8 to 20 weeks for space-grade screened lots. Engineers should plan for lot acceptance testing per MIL-STD-883 and may need to request radiation test data confirming TID tolerance at the desired dose level before integration into satellite or launch vehicle designs.
