The SN74LVC1G66 single, bilateral analog switch is designed for 1.65V to 5.5V VCC operation, and supports both analog and digital signals. SN74LVC1G66 permits bidirectional transmission of signals with amplitudes of up to 5.5V (peak). By using the die as the package, NanoFree package technology represents a significant advancement in IC packaging concepts.
