Features - 15V digital or ±7.5V peak-to-peak switching - 125Ω typical on-state resistance for 15V operation - Switch on-state resistance matched to within 5Ω over 15V signal-input range - On-state resistance flat over full peak-to-peak signal range - High on or off output-voltage ratio: 80d B typical at fis = 10k Hz, RL = 1kΩ - High degree of linearity: <0.5% distortion typical at fis = 1k Hz, Vis = 5Vp-p VDD - VSS ≥ 10V, RL = 10kΩ - Extremely low off-state switch leakage, resulting in very low offset current and high effective off-state resistance: 10 p A typical at VDD - VSS = 10V, TA = 25°C - Extremely high control input impedance (control circuit isolated from signal circuit): 1012Ω typical - Low crosstalk between switches: - 50d B typical at fis = 8MHz, RL = 1kΩ - Matched control-input to signal-output capacitance: reduces output signal transients - Frequency response, switch On = 40MHz typical - 100% tested for quiescent current at 20V - 5V, 10V, and 15V parametric ratings 2 Applications - Analog signal switching and multiplexing: signal gating, modulators, squelch controls, demodulators, choppers, mutating switches - Digital signal switching and multiplexing - Analog-to-digital and digital-to-analog conversions - Digital control of frequency, impedance, phase, and analog-signal gain - Building automation 3 Description The CD4066B device is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin patible with the CD4016B device, but exhibits a much lower onstate 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...
