The CD4066BC is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with CD4016BC, but has a much lower "ON" resistance, and "ON" resistance is relatively constant over the input-signal range.
Features
Wide supply voltage range 3V to 15V
High noise immunity 0.45VDD
Wide range of digital and ±7.5V Peak analog switching
"ON" resistance for 15V operation 80Ω
Matched "ON" resistance ΔR ON=5Ω over 15V signal input
"ON" resistance flat over peak-to-peak signal range
High "ON"/"OFF" 65dB (typ.) output voltage ratio
High degree linearity 0.1% distortion (typ.)
Extremely low "OFF" 0.1nA (typ.) switch leakage
Extremely high control input impedance
Low crosstalk -50dB (typ.) between switches
Frequency response, switch "ON" 40MHz (typ.)
