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

s Wide supply voltage range

3V to 15V

s Wide range of digital and

±7.5 V

PEAK

analog switching

s “ON” resistance for 15V operation 80

Ω

s Matched “ON” resistance

∆R

over 15V signal input

s “ON” resistance flat over peak-to-peak signal range

s High “ON”/“OFF” 65 dB (typ.)

output voltage ratio

s Control Line Biasing:

s High degree linearity 0.1% distortion (typ.)

High degree linearity

High degree linearity

s Extremely low “OFF” 0.1 nA (typ.)

switch leakage:

Ω(typ.)

s Low crosstalk

−50 dB (typ.)

between switches

s 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

Ordering Code:

Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
