CD4066BC
Quad Bilateral Switch
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
n Wide supply voltage range 3V to 15V
n High noise immunity 0.45 VDD (typ.)
n Wide range of digital and ±7.5 VPEAK
analog switching
n “ON” resistance for 15V operation 80W
n Matched “ON” resistance DRON=5W (typ.)
over 15V signal input
n “ON” resistance flat over peak-to-peak signal range
n High “ON”/“OFF” 65 dB (typ.)
output voltage ratio @ fis = 10 kHz, RL = 10 kW
n High degree linearity 0.1% distortion (typ.)
High degree linearity @ fis = 1 kHz, Vis = 5Vp-p,
High degree linearity VDD-VSS = 10V, RL = 10 kW
n Extremely low “OFF” 0.1 nA (typ.)
switch leakage: @ VDD-VSS = 10V, TA = 25°C
n Extremely high control input impedance 1012W(typ.)
n Low crosstalk -50 dB (typ.)
between switches @ fis = 0.9 MHz, RL = 1 kW
n Frequency response, switch “ON” 40 MHz (typ.)
