Overview

Multiplex SDIO or Memory Stick Interfaces
Ideal for High Speed Switching Applications
- Low On-Resistance 4Ω (typ)
- Low-Capacitance Switches, 30pF (typ)
Minimize Switching Foot print through High Integration
- MAX4947 triple double-pole/double-throw (DPDT) switch
- MAX4748 hex single-pole/double-throw (SPDT) switch
- One control logic input
- Small 25-Bump UCSP™ (2.5mm x 2.5mm) or 24- TQFN (4mm x 4mm)
Wide Supply Capability
- 1.8V to 5.5V Supply Voltage Range Rail-to-Rail Signal Handling

The MAX4947/MAX4948 analog switches operate from a single +1.8V to +5.5V supply. These switches feature a low 30pF (typ) capacitance for high-speed data switching applications.

The MAX4947 is a triple double-pole/double-throw (DPDT) switch, and the MAX4748 is a hex single-pole/double-throw (SPDT) switch with one control logic input. The MAX4947 has three logic inputs to control the switches in pairs. The MAX4948 has one logic input and an enable input (active-low EN) to disable the switches.

The MAX4947/MAX4948 are available in small 24-pin (4mm x 4mm) TQFN and 25-bump (2.5mm x 2.5mm) chip-scale packages (UCSP™).

Product Details

The MAX4948 evaluation kit (EV kit) evaluates the MAX4948 hex single-pole/double-throw (SPDT) data switch. The EV kit utilizes the MAX4948 in a Secure Digital (SD) card application. The EV kit provides two SD card sockets and a single SD card printed-circuit board (PCB) plug. The supply voltage provided by the host interface powers the MAX4948 IC and any connected SD memory cards.

The MAX4948 EV kit is a customized PCB with an SD plug designed into the board. The PCB plug is designed to resemble an SD memory card's mechanical dimensions. The PCB plug measures 50.8mm x 24mm x 1.4mm. The mechanical specifications of an actual SD memory card can be obtained from the SD Card Association.
