MAX4947

www.DataSheet4U.com 19-0673; Rev 0; 11/06 Hex SPDT Data Switch 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 switching applications. The MAX4947 is a triple double-pole/double-throw (DPDT) switch, and the MAX4748 is a hex single-pole/doublethrow (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™). ♦ ♦ ♦ ♦ ♦ ♦ 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) MAX4947/MAX4948 Ordering Information PART MAX4947EBA+* MAX4947ETG+ MAX4948EBA+* MAX4948ETG+* TEMP RANGE -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C PINPACKAGE 25 UCSP-25 24 TQFN-EP 25 UCSP-25 24 TQFN-EP PKG CODE B25-1 T2444-4 B25-1 T2444-4 Applications USB Signal Switching UART Signal Switching SDIO/Memory Stick Cell Phones PDAs * Future product—contact factory for availability. + Denotes lead-free package.
