What are the key features of HCC4021BDG?
- Radiation-hardened CMOS 4000B-series logic operating across wide supply voltages from 3 V to 15 V for space and military environments
- 8-bit parallel-in serial-out shift register enabling compact serial data reduction from parallel bus signals
- Ceramic glass-sealed 16-pin DIP package providing superior hermeticity and reliability in high-temperature or radiation-exposed applications
What is HCC4021BDG used for?
The HCC4021BDG is intended for radiation-hardened data acquisition and telemetry systems in space and defense platforms where CMOS 4000B logic must survive ionizing radiation. Its 8-bit parallel-in serial-out architecture is used in satellite instrument interfaces and avionics bus encoders that convert parallel sensor data into serial streams for transmission over 3 V to 15 V logic buses.

Frequently Asked Questions
What supply voltage range does the HCC4021BDG support for space and military system compatibility?
The HCC4021BDG operates from 3 V to 15 V supply voltage, a characteristic of the CMOS 4000B-series logic family, allowing it to interface directly with both low-voltage digital logic rails and higher 12 V or 15 V buses common in radiation-hardened avionics and satellite subsystems.
Why is the ceramic glass-sealed package of the HCC4021BDG important for space and defense applications?
The ceramic glass-sealed 16-pin DIP package of the HCC4021BDG provides hermetic sealing that prevents moisture ingress and outgassing, which are critical requirements for long-duration space missions where temperature swings of -55°C to +125°C and vacuum exposure would degrade plastic-encapsulated devices over time.
How does the HCC4021BDG's 8-bit parallel-in serial-out function simplify telemetry data encoding?
The HCC4021BDG loads 8 bits of parallel input data simultaneously and clocks them out serially in sequence, reducing the number of signal wires needed to transmit 8-channel parallel bus status over long cable runs in space instruments, cutting harness mass by up to 7 wires per shift register used.
