MAX4551EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551EPE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independently controlled switches with normally closed (NC) contacts. The device operates on dual supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include an on-resistance of up to 120Ω at ±5V supplies, on-resistance flatness of 8Ω max, and channel-to-channel matching of 4Ω max. Off-leakage current is typically 1nA at +25°C. The component provides ±15kV ESD protection per IEC 1000-4-2 and supports Rail-to-Rail signal handling.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EPE' corresponds to the 16-pin Plastic DIP package and the -40°C to +85°C extended temperature range. Confirm that the NC configuration matches the system requirements, as the MAX4552 variant offers NO switches and the MAX4553 offers a mixed configuration. Ensure supply voltage limits do not exceed the absolute maximum differential rating of 13.0V.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low power consumption below 1µW is required alongside robust ESD protection. The device is suitable for applications requiring rail-to-rail signal swing and compatibility with standard logic levels. Consider the 120Ω on-resistance limit for signal integrity in high-impedance circuits. Verify that the 16-pin DIP package fits the available board space and assembly constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4551/MAX4552/MAX4553 family of quad SPST analog switches. The MAX4551 specifically denotes the version with four normally closed switches. Other variants in the series include the MAX4552 (four normally open) and MAX4553 (two NC, two NO). All share identical pinouts and electrical characteristics except for the default switch state.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin-compatibility with industry-standard DG211, DG212, and DG213 devices. These can be considered for functional replacement if the package and temperature range align.
