Overview
The Texas Instruments CD4066BE is a CMOS Quad Bilateral Switch, designed for the transmission or multiplexing of analog or digital signals. This device is part of the CD4066B series and is known for its low on-state resistance and wide operating supply range. It is pin-for-pin compatible with the CD4016B but offers a significantly lower on-state resistance, making it suitable for a broad array of applications. The CD4066BE is available in a 14-pin PDIP package and is recommended for new designs due to its active lifecycle status.
