3 Description

This dual bilateral analog switch is designed for

1.65-V to 5.5-V VCC operation.

The SN74LVC2G66 device can handle both analog

and

digital

signals.

The

SN74LVC2G66

device

permits signals with amplitudes of up to 5.5 V (peak)

to be transmitted in either direction.

NanoFree

package

technology

is

a

major

breakthrough in IC packaging concepts, using the die

as the package.

Each switch section has its own enable-input control

(C). A high-level voltage applied to C turns on the

associated switch section.

Applications

include

signal

gating,

chopping,

modulation or demodulation (modem), and signal

multiplexing for analog-to-digital and digital-to-analog

conversion systems.
