Frequently Asked Questions
What is the on-state resistance of the CD4066BME4?
The CD4066BME4 has a maximum on-state resistance (Ron) of 1050 ohms with a nominal on-state resistance matching of 15 ohms between the four switches. This resistance matching ensures consistent signal attenuation across all channels in precision analog switching applications.
How many switches does the CD4066BME4 contain?
The CD4066BME4 contains four independent single-pole single-throw (SPST) normally-open analog switches in a single 14-pin SOIC package. Each switch can be independently controlled, allowing flexible analog signal routing in multiplexer and demultiplexer configurations.
What package does the CD4066BME4 use?
The CD4066BME4 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, suitable for surface mount assembly. It is compatible with standard SOIC PCB footprints and supports lead-free manufacturing processes per JESD-609 e4 classification.
What type of signals can the CD4066BME4 switch?
The CD4066BME4 can switch both analog and digital signals in a bilateral (bidirectional) manner. It supports signal levels up to the supply voltage range and operates with a -5V nominal negative supply, making it suitable for audio, sensor, and general-purpose analog switching applications.
Can the CD4066BME4 replace the CD4016 analog switch?
Yes, the CD4066BME4 is an improved version of the CD4016, offering significantly lower on-state resistance (typically 80 ohms vs 400 ohms at 10V) while maintaining pin and functional compatibility. It is the preferred replacement for CD4016 in applications requiring lower signal loss and better linearity.
