Applications
The HCC4067BF is used in data acquisition systems to route one of 16 analog input signals to a single ADC, reducing component count and cost. It suits industrial process control, audio signal switching, and automated test equipment where multiple channels must be sampled sequentially. Its 40 dB isolation makes it reliable in environments with interfering adjacent-channel signals.

Frequently Asked Questions
How many analog channels can the HCC4067BF switch, and how are they selected?
The HCC4067BF switches 16 single-ended analog channels, selected via a 4-bit binary address input (A0–A3), enabling a microcontroller to route any of the 16 inputs to a common output pin. This 16-channel design reduces wiring and ADC count in multi-sensor data acquisition systems.
What is the on-resistance specification of the HCC4067BF, and why does it matter for precision analog routing?
The HCC4067BF has a maximum on-resistance of 240 Ω and a channel-to-channel matching of 5 Ω. For high-impedance sensor inputs, the 240 Ω series resistance introduces minimal voltage drop, but for low-impedance loads the designer should buffer the output to maintain measurement accuracy within 0.1% or better.
When would the HCC4067BF be preferred over a lower-channel multiplexer such as a 4-channel CD4052 in a sensor scanning application?
The HCC4067BF handles 16 channels versus only 4 channels in a CD4052, cutting board component count by 75% in a 16-sensor scan application. Its 40 dB off-state isolation ensures that unselected channel leakage stays below 1% of full-scale when driving a 10-bit ADC, making it preferable wherever channel density matters.
