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:
