The STG3699B is a high-speed CMOS low voltage quad analog SPDT (single-pole double-throw) switch or 2:1 multiplexer/demultiplexer switch fabricated using silicon gate C2MOS technology. Designed to operate from 1.65 to 4.3 V, this device is ideal for portable applications. It offers very low ON resistance (RON < 0.5 Ω) at VCC = 3.0 V.
