EVALUATION KIT AVAILABLE MAX4947/MAX4948 Hex SPDT Data Switch General Description Benefits and Features The MAX4947/MAX4948 analog switches operate from a Multiplex SDIO or Memory Stick Interfaces single +1.8V to +5.5V supply. These switches feature a Ideal for High Speed Switching Applications low 30pF (typ) capacitance for high-speed data switch- Low On-Resistance 4 (typ) ing applications. Low-Capacitance Switches, 30pF (typ) The MAX4947 is a triple double-pole/double-throw (DPDT) switch, and the MAX4748 is a hex single-pole/double- Minimize Switching Footprint through High Integration throw (SPDT) switch with one control logic input. The MAX4947 triple double-pole/double-throw MAX4947 has three logic inputs to control the switches in (DPDT) switch pairs. The MAX4948 has one logic input and an enable MAX4748 hex single-pole/double-throw (SPDT) input (EN) to disable the switches. switch The MAX4947/MAX4948 are available in small 24-pin One control logic input (4mm x 4mm) TQFN and 25-bump (2.5mm x 2.5mm) Small 25-Bump UCSP (2.5mm x 2.5mm) or 24- chip-scale packages (UCSP). TQFN (4mm x 4mm) Applications Wide Supply Capability 1.8V to 5.5V Supply Voltage Range USB Signal Switching Cell Phones Rail-to-Rail Signal Handling UART Signal Switching PDAs SDIO/Memory Stick Ordering Information and Typical Operating Circuit appears at end of data sheet.

Limit forward-diode current CC to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = +2.7V to +5.5V, T = -40C to +85C, unless otherwise noted.
