The ET3157 is an advanced CMOS analog switch fabricated with silicon gate CMOS technology. It achieves very low propagation delay and RDSON resistances while maintaining CMOS low power dissipation. Analog and digital voltages that may vary across the full power-supply range (from VCC to GND).
The Select pin has over voltage protection that allows voltages above VCC, up to 7.0 V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage.
ET3157 offered in a small SC70-6 or DFN6 package, which is ideal for small form factor portable equipment.
