Key Features
- Radiation-hardened CMOS 4000B dual 4-input OR gate for space and military avionics designs requiring SEE and TID immunity
- Ceramic glass-sealed 14-pin DIP package provides hermetic protection against moisture, outgassing, and mechanical shock in high-reliability assemblies
- Wide supply voltage range of 3 V to 18 V from the CMOS 4000B family supports mixed-voltage and legacy system logic integration
- Dual 4-input OR gate provides 8 total inputs in a single 14-pin package, reducing logic gate count and PCB area in space-constrained avionics boards
- High noise immunity exceeding 45 % of VDD from the 4000B series ensures reliable switching in electrically noisy military and industrial environments
Applications
The HCC4072BDG is used in satellite avionics, military radar signal processing, and nuclear control systems where radiation tolerance and hermetic CMOS logic are required for long-duration mission reliability. Its dual 4-input OR gate function handles combinational logic for fault-detection and voting circuits in redundant control architectures. Industrial applications include high-voltage programmable logic systems and legacy military equipment where the 3 V to 18 V operating range of the 4000B series provides backward compatibility with existing designs.

Frequently Asked Questions
What logic function and input count does the HCC4072BDG implement in a single 14-pin ceramic DIP?
The HCC4072BDG implements two independent 4-input OR gates in a single 14-pin ceramic DIP, providing 8 total logic inputs across both gates. Each gate output goes high when any of its 4 inputs is at a logic high, supporting fault-detection voting logic and interrupt aggregation in radiation-hardened avionics operating from 3 V to 18 V supply.
Which satellite orbit and dose environments can the HCC4072BDG withstand during a long-duration space mission?
The HCC4072BDG is radiation-hardened for total ionizing dose (TID) levels encountered in low-earth-orbit and geosynchronous missions, and it tolerates single-event effects (SEE) from heavy-ion strikes in deep-space trajectories. The 4000B CMOS process maintains correct OR gate switching from 3 V to 18 V supply even after accumulated doses in the tens of krad(Si) range over missions lasting 5 to 15 years.
In what military and industrial system types is the HCC4072BDG a preferred alternative to plastic-package logic gates?
The HCC4072BDG is preferred over plastic-package dual OR gates in military radar electronics, nuclear facility control systems, and avionics signal processors where the hermetic ceramic glass-sealed 14-pin DIP prevents moisture ingress and withstands thermal cycling from -55 °C to +125 °C. Plastic DIP alternatives fail long-duration qualification testing under these conditions, making the ceramic HCC4072BDG the standard choice for high-reliability procurement programs.
How does the 3 V to 18 V supply range of the HCC4072BDG ease integration in mixed-voltage legacy defense equipment?
The CMOS 4000B family 3 V to 18 V supply range lets the HCC4072BDG operate directly on 5 V TTL-compatible rails, 12 V industrial bus supplies, or 15 V analog CMOS rails without level translation. Engineers maintaining legacy military ground-support equipment originally designed for 10 V or 15 V CMOS logic can substitute the HCC4072BDG as a pin-compatible drop-in with no board redesign, reducing engineering hours and qualification risk.
