CD4066BC
Quad Bilateral Switch
■ High degree linearity 0.1% distortion (typ.)
High degree linearity @ fis = 1 kHz, Vis = 5Vp-p
High degree linearity DD−VSS = 10V, RL = 10 kΩ
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.
V
■ 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.)
Features
■ Wide supply voltage range 3V to 15V
between switches @ fis = 0.9 MHz, RL = 1 kΩ
■ High noise immunity 0.45 VDD (typ.)
■ Frequency response, switch “ON” 40 MHz (typ.)
■ Wide range of digital and ±7.5 VPEAK
