The FSA2567 is a bi-directional, low-power, dual double-pole, double-throw (4PDT) analog switch targeted at dual SIM card multiplexing. It is optimized for switching the WLAN-SIM data and control signals and dedicates one channel as a supply-source switch. The FSA2567 is compatible with the requirements of SIM cards and features a low on capacitance (CON) of 10pF to ensure high-speed data transfer. The VSIM switch path has a low RON characteristic to ensure minimal voltage drop in the dual SIM card supply paths.
