Dual Bilateral Analog Switch - SN74AUC2G66


This dual analog switch is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.1-V to 2.7-V VCC operation.

The SN74AUC2G66 can handle both analog and digital signals. It permits signals with amplitudes of up to 2.7-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.

Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.
