MAX391ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391ESE+ is a precision, quad single-pole single-throw normally-closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single supply voltage ranging from 3V to 15V or dual supplies of ±3V to ±8V. The device features a maximum on-resistance of 35 ohms and a channel-to-channel matching of 300 milliohms. Switching times are specified at a maximum of 130ns for turn-on and 75ns for turn-off. It exhibits low charge injection of 2pC and off-state leakage current of 100pA. The component is housed in a 16-SOIC package and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and environmental compliance. Ensure the ordering information matches the required thermal grade and RoHS status for the target application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed state is required upon power-up or control deactivation. Compare the 35-ohm on-resistance and 130ns switching speed against system requirements. Verify that the 16-SOIC footprint fits the PCB layout constraints and that the 0°C to 70°C temperature range meets operational needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX391 series of precision CMOS analog switches. The 'E' suffix typically denotes the SOIC package variant, while the '+' indicates lead-free and RoHS compliance. It serves as a solid-state alternative to mechanical relays in applications requiring fast, silent switching without contact bounce.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other quad SPST NC switches from the same family, such as the MAX392 or MAX393, which offer similar pinouts but may differ in on-resistance or switching polarity. Cross-reference datasheets for electrical parameter compatibility.
