This dual bilateral analog switch is designed for 1.65-V to 5.5-V V_CC operation. Robust LVC family technology allows this device to accept input voltages without connecting power to V_CC.

The SN74LVC2G66-Q1 device permits signals with amplitudes of up to 5.5 V (peak) to be transmitted in either direction. A high-level voltage applied to the control pin C enables the respective switch to begin propagating signals across the device. A low-level voltage disables this transmission. Each device incorporates two switches with independent control and operation.
