MAX4747EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4747EUD+ is a low-voltage, quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals. The device features a maximum on-resistance of 50Ω at +3V and 25Ω at +5V, with channel matching of 3.5Ω at +3V and 3Ω at +5V. Leakage current is guaranteed below 0.1nA at +25°C, and quiescent power consumption is typically less than 0.5nW. It supports TTL/CMOS logic inputs, offers -84dB crosstalk and -72dB off-isolation at 1MHz, and has a -3dB bandwidth of 250MHz. The component is housed in a 14-pin TSSOP package and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and RoHS compliance status. The 'E' indicates an extended temperature range of -40°C to +85°C, while the '+' denotes lead-free construction. Confirm that the 14-pin TSSOP footprint matches your PCB design requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required for low-voltage single-supply operation up to 11V. Ensure the application demands high isolation and low charge injection. Compare against the MAX4748 (NC), MAX4749 (mixed NO/NC), and MAX4750 (SPDT) if different switching topologies are needed for the same package constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4747–MAX4750 family of low-voltage analog switches. While other members offer normally closed or SPDT configurations, the MAX4747 specifically provides four normally open switches. The family shares identical electrical characteristics and packaging options, including WLP and Thin QFN variants, allowing for flexible design choices based on spatial constraints.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include MAX4748EUD+, MAX4749EUD+, and MAX4750EUD+. These parts share the same pinout and electrical specifications but differ in internal switch topology (Normally Closed or SPDT). Verify that the alternative switch state aligns with the circuit design requirements.
