1 / 13 page General Description 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 switch- ing 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 ( 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™). Applications Features ♦ Multiplex SDIO or Memory Stick Interfaces ♦ 1.8V to 5.5V Supply Voltage Range ♦ Low On-Resistance 4Ω (typ) ♦ Low-Capacitance Switches, 30pF (typ) ♦ Rail-to-Rail Signal Handling ♦ Small 25-Bump UCSP™ (2.5mm x 2.5mm) and 24-TQFN (4mm x 4mm) Hex SPDT Data Switch ________________________________________________________________ Maxim Integrated Products 1 Ordering Information MAX4947 S6 S5 COM6 COM5 S4 S3 COM4 COM3 S2 S1 VCC COM2 COM1 GND NO1 NC1 NO2 NC2 NO3 NC3 NO4 NC4 NO5 NC5 NO6 NC6 CB12 CB34 CB56 MAX4948 S6 S5 COM6 COM5 S4 S3 COM4 COM3 S2 S1 VCC COM2 COM1 GND NO1 NC1 NO2 NC2 NO3 NC3 NO4 NC4 NO5 NC5 NO6 NC6 CB EN Functional Diagram 19-0673; Rev 1; 1/07 For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. * Future product—contact factory for availability. + Denotes lead-free package.
