MAX351ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX351ESE is a precision, quad, single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches in a 16-pin Narrow SO package. The device operates with a supply voltage range of ±4.5V to ±20V or +10V to +30V. Electrical characteristics include an on-resistance of 17Ω typical and 35Ω maximum, with guaranteed matching within 2Ω between channels. Leakage current is less than 250pA at +25°C and 6nA at +85°C. Switching times are under 175ns for turn-on and 145ns for turn-off. The component functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'ESE' confirms the narrow SOIC package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as required by project specifications. Ensure the source document explicitly lists this part number to avoid confusion with other variants in the MAX351 family that may have different pin configurations or electrical tolerances.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX351ESE when a quad SPST configuration with normally closed contacts is required. This variant is suitable for designs needing rail-to-rail signal handling and TTL/CMOS logic compatibility. Verify that the narrow SO package dimensions fit the PCB layout constraints. Consider the bipolar or unipolar supply requirements against the system power architecture before finalizing the selection.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX351ESE belongs to the MAX351/MAX352/MAX353 family of precision analog switches. While the MAX352 offers normally open switches and the MAX353 provides a mixed configuration, the MAX351 specifically utilizes four normally closed switches. All three share identical fabrication processes and core electrical performance metrics, differing primarily in their default switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the MAX352ESE and MAX353ESE. These parts share the same package and operating conditions but differ in switch state logic. Verify that the change from normally closed to normally open or mixed states does not impact the circuit's default behavior.
