20V, 1:1 (SPST), 4-channel, analog switch, 10pA on-state leakage current

The CD4066B device is a

quad bilateral switch intended for the transmission or multiplexing of analog or digital

signals. It is pin-for-pin compatible with the CD4016B device, but exhibits a much lower

on-state resistance. In addition, the on-state resistance is relatively constant over the

full signal-input range.

The CD4066B device

consists of four bilateral switches, each with independent controls. Wide operating supply

of 3V to 18V allows for use in a broad array of applications. The advantages over

single-channel switches include peak input-signal voltage swings equal to the full supply

voltage and more constant on-state impedance over the input-signal range. However, for

sample-and-hold applications, the CD4016B device is recommended.
