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. Both the p and the n devices in a given switch are biased on or off simultaneously by the control signal. As shown in Figure 17, the well of the n-channel device on each switch is tied to either the input (when the switch is on) or to VSS (when the switch is off).

CD4016B Series types are quad bilateral switches intended for the transmission or multiplexing of analog or digital signals. Each of the four independent bilateral switches has a single control signal input which simultaneously biases both the p and n device in a given switch on or off. Features:

• 20-V digital or ± 10-V peak-to-peak switching
• 280- typical on-state resistance for 15-V operation
• Switch on-state resistance matched to within 10 typ. over 15-V signal-input range
• High on/off output-voltage ratio: 65 dB typ. @ fis = 10 kHz, RL = 10 k
• High degree of linearity: <0.5% distortion typ. @ fis = 1 kHz, Vis = 5 Vp-p, VDD–VSS
• Extremely low off-state switch leakage resulting in very low offset current and high effective off-state resistance: 100pA typ.
