MAX353CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX353CSE+ is a precision, quad, single-pole single-throw (SPST) analog switch fabricated with an improved 44V silicon-gate process. It features two normally open and two normally closed switches within a 16-pin narrow SOIC package. The device operates on a single positive supply ranging from +10V to +30V or split supplies from ±4.5V to ±20V. Key electrical parameters include an on resistance of less than 35Ω, guaranteed channel matching within 2Ω, and low leakage currents below 250pA at +25°C. Switching performance includes turn-on times under 175ns and turn-off times under 145ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CSE+' against official Analog Devices documentation to confirm the commercial temperature range and lead-free status. Ensure the narrow SOIC package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed switching functions is required in a compact surface-mount form factor. Verify that the operating supply voltage aligns with the specified single or bipolar ranges to maintain the guaranteed on-resistance flatness across the full analog signal path.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX351/MAX352/MAX353 family of precision analog switches. While the MAX351 contains four normally closed switches and the MAX352 contains four normally open switches, the MAX353 uniquely combines two of each type within the same monolithic structure.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include the MAX351CSE+ and MAX352CSE+. These parts share identical pinouts and electrical characteristics but differ in the internal configuration of normally open versus normally closed channels.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX351, MAX352, and MAX353?

The MAX351 contains four normally closed (NC) switches, the MAX352 contains four normally open (NO) switches, and the MAX353 contains two NO and two NC switches.

Can the MAX353 operate with unbalanced power supplies?

Yes, the device can be powered from unbalanced supplies such as +24V and -5V, provided the total voltage difference does not exceed the absolute maximum ratings.
