MAX4551ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551ESE+T 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 contains four normally closed (NC) switches with a maximum on-resistance of 120Ω at ±5V supplies. Key electrical parameters include an on-resistance flatness of 8Ω max, channel-to-channel matching of 4Ω max, and off-leakage current of 1nA at +25°C. Turn-on time is typically 70ns and turn-off time is typically 90ns at ±5V. The component is housed in a 16-pin Narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure the source document explicitly identifies the 'T' suffix as corresponding to tape-and-reel packaging for this part number. Cross-reference manufacturer specifications to validate RoHS compliance status before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4551 variant specifically when normally closed (NC) switch configuration is required upon power-up. Consider the low power consumption of less than 1µW for battery-sensitive designs. Verify that the single-supply operation down to +2.7V meets the system voltage requirements. Ensure the 120Ω maximum on-resistance is acceptable for the application's signal integrity needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4551 is part of the MAX4551/MAX4552/MAX4553 family of quad SPST analog switches. While the MAX4551 provides four normally closed switches, the MAX4552 offers four normally open switches, and the MAX4553 combines two NC and two NO switches. All variants share identical electrical characteristics and pinouts, differing only in the default state of the switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the MAX4552ESE+ and MAX4553ESE+. These parts are electrically compatible but differ in switch configuration: MAX4552 provides four normally open switches, while MAX4553 provides two normally closed and two normally open switches. Verify logic sense inversion if replacing MAX4551 with these alternatives.
