UNISONIC TECHNOLOGIES CO., LTD U74LVC2G66 CMOS IC DUAL BILATERAL ANALOG SWITCH DESCRIPTION The U74LVC2G66 is a dual bilateral analog switch which is designed for 1.65V to 5.5V operation. This switch can handle both analog and digital signals and permits signals with amplitudes of up to 5.5 V (peak) to be transmitted in either direction. Each switch section has enable-input control (C). If the voltage applied to C is at high-level, the associated switch section is turned on.
