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.
