MAX4523CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523CSE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four switches with two normally closed and two normally open configurations. The device operates from dual supplies of ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include an on-resistance of 100Ω maximum at ±5V supplies, matched within 6Ω, and flatness of 12Ω maximum. Off-leakage current is specified at 1nA typical at +25°C. The package is a 16-pin Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CSE+' against the manufacturer's official documentation to confirm the commercial temperature range and lead-free status. Ensure the narrow SOIC package dimensions match the design constraints. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential obsolescence notices.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed analog switching paths is required in a compact footprint. Verify that the 100Ω on-resistance meets the signal integrity requirements for the specific application voltage levels. Confirm compatibility with the system's logic voltage thresholds, particularly if operating near the lower supply limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4521/MAX4522/MAX4523 family of quad analog switches. The MAX4523 variant specifically provides two NO and two NC switches, distinguishing it from the MAX4521 (all NC) and MAX4522 (all NO). The 'C' indicates a commercial temperature range, while 'E' denotes extended range.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements within the same family include MAX4521CSE+ and MAX4522CSE+. For different switch configurations, verify functional equivalence carefully. Extended temperature variants such as MAX4523ESE+ are available if higher thermal performance is required.
