Description

This single analog switch is operational at 0.8-V to 2.7-V V_CC, but is designed specifically for 1.65-V to 1.95-V V_CC operation.

The SN74AUC1G66 can handle both analog and digital signals. The combined AC and DC signal has to be between V_CC and GND for it 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.
