Analog switch provides high signal integrity

The 74LVC1G3157 single-pole, double-throw analog switch operates from a 1.65 to 5.5 V supply and can handle signal amplitudes between Vcc and ground. It includes ESD and latch-up protection, and the ICs low 6 Ω on-state resistance (typical) ensures high integrity when routing audio signals.

The off state impedance of the switch is typically 50 M. Its quiescent supply current is only 40 µA and it comes in a SOT23 or tiny DFN1410 package. From $0.055 ea/3,000.
