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

■ 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.)
