PRELIMINARY DATASHEET IDTHS421V16 Description The IDTHS421V16 is a bi-directional, low power, Quad single-pole, double-throw (SPDT) hybrid 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. This device is compatible with the requirements of SIM cards and features a low on capacitance (C ON ) of 10 pf to ensure high-speed data transfer. The V SIM switch path has a low R ON characteristic to insure minimal voltage drop in the dual SIM card supply paths. The IDTHS421P16 contains special circuitry that minimizes current consumption when the control voltage applied to the SEL pin is lower than the supply voltage (VCC). This feature is especially valuable in ultra-portable applications, such as cell phones; allowing direct interface with the general purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers.
