Frequently Asked Questions
How many independent inverter channels does the HCC4049UBDG provide and what logic family is it compatible with?
The HCC4049UBDG integrates 6 independent single-input inverting buffers, each capable of translating CMOS logic levels to TTL-compatible outputs. It belongs to the CMOS 4000B family and operates over a wide supply voltage range of 3 V to 15 V, enabling direct interfacing between legacy 5 V CMOS boards and modern 3.3 V TTL logic in space and military systems.
What operating temperature range does the HCC4049UBDG support in its ceramic DIP-16 package for aerospace applications?
Housed in a hermetically sealed ceramic CDIP-16 package, the HCC4049UBDG is qualified for the military temperature range of -55 °C to +125 °C, making it suitable for avionics, satellite payloads, and ground-based military electronics exposed to extreme thermal cycling. The ceramic metal-sealed body prevents moisture ingress, extending operational lifetime in vacuum and high-humidity environments beyond what plastic packages can achieve.
When is the HCC4049UBDG preferred over a standard commercial CD4049 in a new radiation-tolerant design?
The HCC4049UBDG is chosen over a commercial CD4049 when the application must survive Total Ionizing Dose (TID) levels above 10 krad(Si) or when single-event latchup (SEL) immunity is required, as the radiation-hard process used by STMicroelectronics maintains logic functionality at doses that would cause parametric degradation in standard CMOS devices. The hermetic 16-pin ceramic package also provides a moisture sensitivity level immune to humidity-induced failure, unlike plastic SOIC-16 alternatives rated only to MSL 1 under commercial conditions.
