Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX4947ETG+T
Analog Switches, Multiplexers, Demultiplexers Overview
The MAX4947ETG+T is a triple double-pole/double-throw (DPDT) analog switch operating from a single +1.8V to +5.5V supply. It features a typical on-resistance of 4Ω and low capacitance of 30pF, making it suitable for high-speed data switching. The device includes three logic inputs to control switches in pairs. It operates within a temperature range of -40°C to +85°C and is housed in a 24-pin TQFN package with an exposed paddle.
Analog Switches, Multiplexers, Demultiplexers Feature Summary
- Triple DPDT configuration with paired logic control
- Low on-resistance and low capacitance for high-speed applications
- Wide supply voltage capability supporting rail-to-rail signal handling
Analog Switches, Multiplexers, Demultiplexers Applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes
Verify the component against official datasheets to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required package type and lead-free status. Cross-reference the manufacturer's documentation for any updates regarding availability or alternative packages.
Analog Switches, Multiplexers, Demultiplexers Selection Notes
Select this component when a compact solution for multiple bidirectional analog signals is required. The triple DPDT structure reduces board space compared to individual SPDT switches. Verify that the supply voltage range aligns with the system design and that the thermal performance of the TQFN package meets the application requirements.
Analog Switches, Multiplexers, Demultiplexers Part Context
This part belongs to the MAX4947/MAX4948 family of hex SPDT data switches. The MAX4947 variant specifically provides a triple DPDT configuration, whereas the MAX4948 offers a hex SPDT setup. Both share similar electrical characteristics and are designed for portable and high-speed digital applications requiring efficient signal routing.
Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
The MAX4948ETG+T serves as a functional substitute within the same family, offering a hex SPDT configuration instead of triple DPDT. Other alternatives may include different packaging options like the UCSP variant if size constraints differ.
