CD4066BCQuad Bilateral SwitchGeneral DescripTIonThe CD4066BC is a quad bilateral switch intended for thetransmission or mulTIplexing of analog or digital signals. It ispin-for-pin compaTIble with CD4016BC, but has a muchlower “ON” resistance, and “ON” resistance is relaTIvelyconstant over the input-signal range.Featuresn Wide supply voltage range 3V to 15Vn High noise immunity 0.45 VDD (typ.)n Wide range of digital and ±7.5 VPEAKanalog switchingn “ON” resistance for 15V operation 80Wn Matched “ON” resistance DRON=5W (typ.)over 15V signal inputn “ON” resistance flat over peak-to-peak signal rangen High “ON”/“OFF” 65 dB (typ.)output voltage ratio @ fis = 10 kHz, RL = 10 kWn High degree linearity 0.1% distortion (typ.)High degree linearity @ fis = 1 kHz, Vis = 5Vp-p,High degree linearity VDD-VSS = 10V, RL = 10 kWn Extremely low “OFF” 0.1 nA (typ.)switch leakage: @ VDD-VSS = 10V, TA = 25°Cn Extremely high control input impedance 1012W(typ.)n Low crosstalk -50 dB (typ.)between switches @ fis = 0.9 MHz, RL = 1 kWn Frequency response, switch “ON” 40 MHz (typ.)Applications• Analog signal switching/multiplexing• Signal gating• Squelch control• Chopper• Modulator/Demodulator• Commutating switch• Digital signal switching/multiplexing• CMOS logic implementation• Analog-to-digital/digital-to-analog conversion• Digital control of frequency, impedance, phase, and analog-signal-gain
