3 Description

The design of this dual bilateral analog switch is for

1.65 V to 5.5 V VCC operation. The SN74LVC2G66-

Q1 can handle both analog and digital signals. The

device permits signals with amplitudes of up to 5.5

V (peak) to be transmitted in either direction. 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.
