MAX4551ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551ESE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices / Maxim Integrated. It features ±15kV 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 includes four normally closed switches with a maximum on-resistance of 120Ω at ±5V supplies. On-resistance is matched between channels to 8Ω max and remains flat within 8Ω over the signal range. Power consumption is less than 1µW, and it supports Rail-to-Rail analog signals.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ESE+' against the manufacturer's current ordering guide to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the SOIC-Narrow-16 configuration. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low power consumption and high ESD robustness are required for single-supply or dual-supply applications. Verify that the 120Ω maximum on-resistance meets system signal integrity requirements. Confirm that the -40°C to +85°C operating temperature range aligns with environmental conditions. Check logic threshold compatibility if interfacing with non-standard digital levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4551 is part of the MAX4551/MAX4552/MAX4553 family of quad SPST analog switches. While the MAX4551 uses normally closed switches, the MAX4552 utilizes normally open switches, and the MAX4553 combines both types. All variants share identical pinouts and electrical characteristics except for the switch state configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin-compatibility with DG211, DG212, and DG213 devices. Verify functional equivalence regarding on-resistance and leakage currents before substitution.
