General Description
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 0.45 VDD (typ.)
■ Wide range of digital and ±7.5 VPEAK analog switching
■ “ON” resistance for 15V operation 80Ω
■ Matched “ON” resistance ∆RON = 5Ω (typ.) over 15V signal input
■ “ON” resistance flat over peak-to-peak signal range
■ High “ON”/“OFF” 65 dB (typ.) output voltage ratio @ fis = 10 kHz, RL = 10 kΩ
■ Control Line Biasing:
   Switch On (Logic 1), VC = VDD
   Switch Off (Logic 0), VC = VSS
■ High degree linearity 0.1% distortion (typ.)
   High degree linearity @ fis = 1 kHz, Vis = 5Vp-p,
   High degree linearity VDD−VSS = 10V, RL = 10 kΩ
■ Extremely low “OFF” 0.1 nA (typ.) switch leakage: @ VDD−VSS = 10V, TA = 25°C
■ Extremely high control input impedance 1012Ω(typ.)
■ Low crosstalk −50 dB (typ.) between switches @ fis = 0.9 MHz, RL = 1 kΩ
■ Frequency response, switch “ON” 40 MHz (typ.)
