open-in-new Find other Analog switches & muxes

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.
