The CD4066B 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, but exhibits a much lower on-state resistance.

Features of CD4066 Quad Bilateral Switch:

• 15-V Digital or ±7.5-V Peak-to-Peak Switching.
• 125- Typical On-State Resistance for 15-V Operation.
• Switch On-State Resistance Matched to Within 5 Over 15-V Signal-Input Range.
• On-State Resistance Flat Over Full Peak-to-Peak Signal Range.
• High On/Off Output-Voltage Ratio: 80 dB Typical at fis = 10 kHz, RL = 1 k.
• High Degree of Linearity: < 0.5% Distortion Typical at fis = 1 kHz, Vis = 5 V p-p, VDD–VSS .
• Extremely Low Off-State Switch Leakage, Resulting in Very Low Offset Current and High Effective Off-State Resistance: 10 pA Typical at VDD–VSS = 10 V, TA = 25°C.
• Extremely High Control Input Impedance (Control Circuit Isolated From Signal Circuit): 1012 Typical.
• Low Crosstalk Between Switches: –50 dB Typical at fis = 8 MHz, RL = 1 k.
• Matched Control-Input to Signal-Output Capacitance: Reduces Output Signal Transients.
• Frequency Response, Switch on = 40 MHz (Typical).
• 100% Tested for Quiescent Current at 20 V.
• 5-V, 10-V, and 15-V Parametric Ratings.

Applications of CD4066 Quad Bilateral Switch:

• Analog Signal Switching/Multiplexing.
• Signal Gating, Modulator, Squelch Control, Demodulator, Chopper, Commutating Switch.
• Digital Signal Switching/Multiplexing.
• Transmission-Gate Logic Implementation.
• Analog-to-Digital and Digital-to-Analog Conversion.
• Digital Control of Frequency, Impedance, Phase, and Analog-Signal Gain.
