MAX4551CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551CSE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features ±15kV electrostatic discharge (ESD) protection per IEC 1000-4-2 and operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. The device provides four separately controlled switches with an on-resistance of 120Ω maximum at ±5V supplies and flatness of 8Ω maximum over the signal range. Off-leakage current is 1nA at +25°C and 10nA at +85°C. It supports Rail-to-Rail analog signals and includes TTL/CMOS-compatible inputs. The component is housed in a 16-pin Narrow SO package and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the 16-pin Narrow SO package and the commercial temperature range of 0°C to +70°C. Confirm that the ordering information matches the manufacturer's current part numbering system, as legacy Maxim products may have updated designations. Ensure the datasheet revision aligns with the required specifications for your application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4551CSE when four normally closed SPST switches are required. Compare on-resistance and leakage requirements against the MAX4552 (normally open) and MAX4553 (mixed) variants if the switching state differs. Consider the ±15kV ESD rating for robust designs and verify supply voltage constraints fit within the specified single or dual supply ranges.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4551CSE belongs to the MAX4551/MAX4552/MAX4553 family of low-voltage CMOS analog switches. This series is designed for applications requiring high reliability and ESD immunity. The CSE designation specifically identifies the commercial grade version in the 16-pin Narrow SOIC package, distinguishing it from the extended temperature ESE variant or other package types like QSOP or DIP.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4551CSE is pin-compatible with the DG211. Verify that substitute components meet the same ±15kV ESD protection level and on-resistance specifications to ensure functional equivalence in existing circuit layouts.
