MAX4519CSD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4519CSD is a precision, monolithic CMOS analog multiplexer featuring dual 2-channel configuration in a 14-pin SO package. It operates with single supplies from +2.7V to +15V or bipolar supplies from ±2.7V to ±8V. The device guarantees on-resistance less than 100Ω, matched within 4Ω between channels, and maintains flatness of 10Ω maximum over the signal range. Key electrical parameters include off-leakage current below 2nA at +85°C, charge injection under 5pC, and transition times under 250ns. It provides electrostatic discharge protection exceeding 2000V and supports rail-to-rail signal handling with TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSD' corresponds to the commercial temperature range (0°C to +70°C) and 14-pin SO package as documented in the official ordering information. Confirm RoHS compliance status through the manufacturer's current documentation, as legacy Maxim Integrated products may have varying environmental certifications depending on production batches.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4519CSD when a dual 2-channel multiplexer is required rather than the 4-channel MAX4518 variant. Ensure the application voltage does not exceed the absolute maximum ratings of +17V or -17V relative to ground. Verify that the required switching speed and leakage specifications align with the guaranteed electrical characteristics provided in the datasheet tables.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4519CSD belongs to the MAX4518/MAX4519 family of precision, low-voltage CMOS analog multiplexers manufactured by Analog Devices / Maxim Integrated. This series is designed for applications requiring low on-resistance and fast switching speeds while operating from low-voltage single or dual power supplies.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options within the same family include the MAX4519EEE (16-pin QSOP package) or MAX4519CPD (14-pin Plastic DIP). These variants share identical electrical characteristics but differ in physical package dimensions and pin configurations.
