MAX391CSE+TG002

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391CSE+TG002 is a precision, quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches and operates from a single +3V to +15V supply or dual ±3.0V to ±8V supplies. Key electrical parameters include a maximum on-resistance of 35Ω at ±5V, a maximum turn-on time of 130ns, and a maximum turn-off time of 75ns. The device offers low power consumption of 1µW, low leakage current of 100pA, and charge injection of 5pC. It is housed in a 16-pin Narrow SOIC package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact packaging and tape specifications. Ensure the component matches the required temperature grade and package variant for your design. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with normally closed contacts is required. Consider the 35Ω maximum on-resistance and 130ns switching speed for signal integrity requirements. Verify that the single or dual supply voltage ranges align with your system's power architecture and that the narrow SOIC package fits your PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX391 is part of the MAX391/MAX392/MAX393 family of precision analog switches. While the MAX391 provides four normally closed switches, the MAX392 offers four normally open switches, and the MAX393 combines two normally open and two normally closed switches. All three devices share similar electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX392 and MAX393, which offer different switch configurations but identical pinouts and electrical performance.
