What are the key features of HCC4094BDG?
- Radiation-hardened CMOS design for space and military applications
- 8-bit serial-in parallel-out shift register for data expansion
- Ceramic glass-sealed 16-pin DIP package for extreme environment reliability
- Wide supply voltage range typical of CMOS 4000B family
- True output polarity with single function 8-bit data latching
What is HCC4094BDG used for?
The HCC4094BDG is targeted at radiation-hardened digital logic applications in satellites, spacecraft electronics, and military avionics where conventional CMOS would fail due to ionizing radiation exposure. As an 8-bit serial-in parallel-out shift register it can be used for I/O port expansion, data serialization, and LED/display driver control in harsh-environment embedded systems. The ceramic glass-sealed package ensures hermeticity and long-term reliability in temperature extremes from -55°C to +125°C.

Frequently Asked Questions
Why is the HCC4094BDG packaged in a ceramic glass-sealed DIP rather than standard plastic packaging?
The HCC4094BDG uses a ceramic glass-sealed 16-pin DIP package to provide hermetic sealing, which protects the die from moisture, contaminants, and atmospheric gases. This is mandatory for space and military applications where temperature extremes from -55°C to +125°C and radiation environments would degrade or destroy plastic-packaged components over time. Ceramic packages also offer superior thermal stability and long storage life exceeding 20 years.
How does the 8-bit serial-in parallel-out architecture of the HCC4094BDG enable output expansion in radiation-tolerant systems?
The HCC4094BDG shifts 8 bits of serial data into internal latches and then presents all 8 outputs simultaneously in parallel, allowing a microcontroller with only 2 or 3 digital I/O pins to control 8 parallel outputs. This is ideal for driving status LEDs, relay arrays, or sensor enable lines in spacecraft and satellite bus controllers where minimizing I/O pin count reduces microcontroller complexity and radiation-sensitive die area.
When would a designer choose HCC4094BDG over a commercial-grade 4094 shift register in a new board design?
A designer selects the HCC4094BDG when the application must withstand total ionizing dose radiation levels typical in low-Earth orbit or geostationary orbit, typically exceeding 10 krad(Si), where a commercial-grade 4094 would latch up or degrade within months. The radiation-hardened CMOS process ensures correct 8-bit shift-register operation throughout the mission lifetime, while the ceramic glass-sealed package maintains electrical performance at temperature extremes that would cause standard plastic parts to fail.
