MAX4551CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551CEE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch featuring ±15kV ESD protection. It operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. The device includes four normally closed switches with an on-resistance of 100Ω max, matched to 4Ω max, and flat within 8Ω max over the signal range. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Digital inputs have thresholds of +0.8V and +2.4V for TTL/CMOS compatibility. Power consumption is less than 1µW. The component is housed in a 16-pin QSOP package and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CEE confirms the commercial temperature range of 0°C to +70°C and the 16-pin QSOP package configuration. Confirm RoHS compliance status as historical documentation may vary by manufacturing date. Ensure the source document matches the official Analog Devices datasheet for accurate electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independently controlled SPST switches are required in a compact surface-mount package. The MAX4551 variant specifically provides four normally closed contacts, distinguishing it from the MAX4552 (normally open) and MAX4553 (mixed). Verify that the single-supply operation down to +2.7V meets the system power constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4551/MAX4552/MAX4553 family of low-voltage CMOS analog switches manufactured by Maxim Integrated, now part of Analog Devices. The family shares identical pinouts and core switching characteristics, differing primarily in the default state of the internal contacts (Normally Closed vs. Normally Open).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with industry-standard DG211, DG212, and DG213 devices. These can serve as direct functional replacements if mechanical footprint and electrical parameters align with the application requirements.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4551 handle ESD events on the analog pins?

The device incorporates bidirectional SCRs on the NC/NO pins that turn on during ESD strikes to bypass surge current safely to ground, preventing latchup or damage up to ±15kV per IEC 1000-4-2.

What is the difference between the MAX4551 and MAX4552?

The MAX4551 contains four normally closed (NC) switches, whereas the MAX4552 contains four normally open (NO) switches. Both share the same package and electrical characteristics.

Can the MAX4551 operate with a single supply?

Yes, the device operates with a single supply between +2V and +12V when the V- pin is connected to GND. It is fully specified for single +2.7V operation.
