What are the key features of HCC4020BDG?
- Radiation-hardened 14-stage ripple-carry binary counter designed for space, satellite, and nuclear applications requiring SEL and TID tolerance
- Wide 3 V to 18 V VDD operating range ensures compatibility with diverse power architectures in rad-hard embedded systems
- Hermetic ceramic 16-pin DIP package provides long-term reliability across -55°C to +125°C in harsh vacuum and high-radiation environments
What is HCC4020BDG used for?
The HCC4020BDG is designed for frequency division, timing generation, and event counting in radiation-hardened satellite systems, nuclear plant instrumentation, and military avionics where CMOS logic must survive ionizing radiation. Its 14-stage binary counter divides clock frequencies by up to 16,384, enabling long-duration timing sequences from a single oscillator in autonomous remote systems. The hermetic ceramic DIP-16 package protects against vacuum outgassing, moisture ingress, and the mechanical stresses of spaceflight environments.

Frequently Asked Questions
How many counting stages does the HCC4020BDG provide, and what maximum frequency division ratio is achievable?
The HCC4020BDG is a 14-stage ripple-carry binary counter that divides the input clock frequency by powers of 2, reaching a maximum division ratio of 16,384 at the Q14 output, with 13 output stages externally accessible. It operates from a 3 V to 18 V supply and is suited for frequency division chains, long-duration timers, and pulse counting circuits in radiation-hardened space and nuclear systems.
What makes the HCC4020BDG suitable for space and radiation environments compared to standard CD4020 counters?
The HCC prefix on STMicroelectronics HCC4020BDG indicates radiation hardening, qualifying it for high total ionizing dose environments and single-event latch-up immunity beyond the capability of standard CD4020 or HEF4020 parts. It operates from 3 V to 18 V VDD, maintains full functionality from -55°C to +125°C, and is housed in a hermetic ceramic DIP-16 package that withstands vacuum, moisture, and ionizing radiation encountered in LEO satellite and nuclear applications.
How does the asynchronous master reset of HCC4020BDG support deterministic startup in mission-critical designs?
The HCC4020BDG features an asynchronous master reset (MR) input that clears all counter stages to zero independently of the clock, allowing fast and deterministic initialization within nanoseconds of power-up across the full 3 V to 18 V supply range. This is critical for safety-certified avionics and radiation-hardened satellite command decoders where undefined counter states at startup could trigger erroneous system responses.
