Frequently Asked Questions
How many analog input channels does the HCC4051BKG support and what is its supply voltage range?
The HCC4051BKG supports 8 single-ended analog input channels that are routed to a single common output. The device operates across a wide supply voltage range of up to 20 V, making it compatible with both 5 V and 15 V CMOS logic systems used in space and high-reliability industrial equipment.
For which mission-critical applications is the HCC4051BKG radiation-hardened CMOS multiplexer best suited?
This part is best suited for satellite telemetry systems, space-qualified data acquisition units, and avionics signal multiplexers where total ionizing dose (TID) tolerance is required. The ceramic metal-sealed co-fired flat-16 package provides hermetic protection across an operating temperature range of -55°C to +125°C for long-duration space missions.
What package does the HCC4051BKG use and how does it differ from commercial CMOS 4051 variants?
The HCC4051BKG uses a ceramic co-fired flat-16 (FLAT16 ESA FP) package, which differs fundamentally from the plastic DIP or SOIC packages used by commercial CD4051 variants. The hermetic ceramic enclosure provides superior moisture resistance and meets ESA (European Space Agency) qualification standards, commanding a significant price premium over plastic commercial parts.
What is the on-resistance and signal bandwidth capability of the HCC4051BKG analog switches?
As a CMOS4000B-series device, the HCC4051BKG analog switches exhibit typical on-resistance below 300 Ω at a 5 V supply and decreasing to approximately 100 Ω at 15 V. This low on-resistance, combined with an 8-channel mux structure, supports audio-frequency and low-frequency instrumentation signal paths where signal integrity across 8 inputs is critical.
