MAX4551ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551ESE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./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 flatness is limited to 8Ω max, and channel-to-channel matching is within 4Ω max. Supply current is typically 1µA, and the component supports Rail-to-Rail signal handling.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature range and package type. The 'E' suffix indicates an industrial temperature range of -40°C to +85°C, while 'C' denotes commercial range. Confirm RoHS compliance status through manufacturer datasheets. Ensure pinout alignment matches the target design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high ESD robustness is required without external protection circuitry. The MAX4551 variant specifically provides four normally closed switches, distinguishing it from the NO configuration in MAX4552. Evaluate power supply constraints, as the device supports both single and dual supply architectures. Consider the 120Ω maximum on-resistance for applications where signal attenuation must be minimized.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4551/MAX4552/MAX4553 family of low-voltage SPST analog switches. The MAX4551 specifically integrates four normally closed switches, whereas the MAX4552 contains four normally open switches, and the MAX4553 combines two of each. All variants share identical pinouts and electrical characteristics except for the switch state logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with DG211, DG212, and DG213. Verify that the legacy components meet the same ESD protection levels if replacing them with the MAX4551ESE+. Check supply voltage tolerances to ensure the new device operates within its specified limits.
