What is CD4067BF3A used for?
The CD4067BF3A is designed for analog signal routing in military avionics, spacecraft, and industrial test equipment where operation across the full -55°C to +125°C temperature range is required. Its 16-channel configuration allows a single device to route one of 16 analog inputs to a common output, simplifying multichannel sensor scanning and signal distribution in data acquisition systems. The ceramic package ensures hermeticity and reliability in harsh environments where plastic-packaged ICs would fail due to moisture ingress or thermal stress.

Frequently Asked Questions
What is the on-state resistance of the CD4067BF3A, and how does it affect signal integrity in a multiplexed analog circuit?
The CD4067BF3A has a maximum on-state resistance of 1050 Ω, with channel matching of 15 Ω between channels. In a multiplexed ADC front-end, this series resistance forms an RC low-pass filter with the ADC's input capacitance, limiting high-frequency signal bandwidth. For a 10 pF ADC input capacitor, the resulting RC cutoff frequency is approximately 15 MHz, which is adequate for DC and audio-rate signals but should be considered for high-frequency analog routing applications.
Why does the CD4067BF3A use a ceramic DIP package instead of plastic, and for which environments is this critical?
The CD4067BF3A uses a ceramic glass-sealed 24-pin DIP package to provide hermetic protection against moisture, corrosion, and outgassing in vacuum environments. This is essential for military avionics, satellite systems, and downhole oil exploration equipment operating at temperatures from -55°C to +125°C, where standard plastic packages would absorb moisture, delaminate, or crack. Ceramic-packaged parts also maintain consistent performance across their full temperature range with no degradation over 20-year mission lifetimes.
How does the 16-channel configuration of CD4067BF3A simplify multichannel sensor scanning compared to using multiple 4-channel multiplexers?
A single CD4067BF3A selects among 16 inputs using only 4 binary address pins, allowing one device to scan 16 sensors while consuming 24 pins of PCB space. Using four 4-channel multiplexers to achieve the same 16-input coverage requires 4 separate ICs with independent enable signals, increasing board area and routing complexity. The 14 MHz bandwidth of the CD4067BF3A also supports faster channel switching for high-speed data acquisition systems requiring sub-microsecond settling times.
