Key Features
- Radiation-hardened 4-bit binary up/down counter designed for space-grade and high-reliability systems requiring immunity to single-event upsets
- Bidirectional count direction with asynchronous parallel load/preset input allows flexible sequencing without relying on synchronous timing constraints
- Ceramic 16-pin DIP package provides hermetic sealing and wide temperature-range operation suited for aerospace, defense, and harsh-environment deployments
Applications
HCC4516BDG is intended for radiation-tolerant digital systems in satellites, launch vehicles, and high-reliability industrial equipment where standard plastic-packaged counters would accumulate single-event errors. Its 4-bit presettable up/down count capability supports address sequencing, pulse counting, and frequency division in space-borne instrument electronics. The ceramic DIP-16 package ensures hermeticity and mechanical reliability across the full military temperature range from -55°C to 125°C.

Frequently Asked Questions
Why is the ceramic package on HCC4516BDG important for satellite applications operating in a radiation environment?
The 16-pin ceramic DIP (CDIP) package provides hermetic sealing that prevents moisture ingress and outgassing in a vacuum, which is critical for satellite components operating in orbit. Ceramic packages also exhibit better thermal cycling stability over the -55°C to 125°C range compared to plastic DIP packages, reducing solder joint fatigue during the thermal cycles experienced in low-Earth orbit.
What count modulus does HCC4516BDG support, and how can cascading multiple devices extend the count range?
HCC4516BDG is a 4-bit counter with a natural count modulus of 16 (0 to 15). Two devices can be cascaded by connecting the carry-out of the lower nibble to the clock input of the upper nibble, extending the count to 8 bits and a modulus of 256. Four cascaded devices yield 16-bit counting up to 65,535, suitable for long-duration event counting in space instrument telemetry.
How does the asynchronous preset function of HCC4516BDG help in time-to-digital converter designs?
The parallel load/preset input allows the counter to be loaded with a specific 4-bit start value asynchronously, without waiting for the next clock edge. In a time-to-digital converter, this allows the counter to be reset to a known state—such as 0 or a mid-scale value—within one gate delay after a trigger event, removing the 0 to 1 clock cycle uncertainty that a synchronous reset would introduce.
What is the supply voltage range of HCC4516BDG, and how does the HC CMOS family perform at the extremes?
HCC4516BDG operates from a 3 V to 18 V supply as part of the HC CMOS logic family, which delivers improved noise immunity and output drive compared to standard 4000-series CMOS. At 5 V, the propagation delay is typically below 100 ns, and the output can source or sink several milliamps, making it compatible with TTL-level inputs of other logic devices in mixed-logic space-board designs.
When would a designer select HCC4516BDG over a standard plastic-packaged CD4516 counter for an aerospace instrument?
HCC4516BDG is selected when the design must meet radiation tolerance requirements—such as a total ionizing dose above 10 krad(Si) or latch-up immunity—that standard CD4516 in plastic packages cannot guarantee. The hermetic ceramic package also satisfies MIL-STD-883 screening requirements for Class B or Class S space components, whereas commercial CD4516 parts are not qualified to those standards.
