MAX4551CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4551CPE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch housed in a 16-pin Plastic DIP package. It operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. The device features four normally closed switches with an on-resistance of up to 120Ω at ±5V supplies and flatness within 8Ω. It provides ±15kV ESD protection per IEC 1000-4-2 and supports rail-to-rail analog signal handling. Operating temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPE confirms the 0°C to +70°C commercial temperature grade and 16-pin PDIP package configuration. Ensure the ordering documentation matches the manufacturer's standard part numbering system to confirm the NC switch configuration inherent to the MAX4551 series designation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require normally closed analog paths with low voltage operation. Verify that the required on-resistance and leakage current specifications align with the provided electrical characteristics tables for the intended supply voltage and temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4551/MAX4552/MAX4553 family of low-voltage analog switches. The MAX4551 variant specifically utilizes four normally closed switches, distinguishing it from the MAX4552 which uses normally open switches. The family shares identical pinouts and general electrical performance profiles.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with industry-standard DG211/DG212/DG213 devices. Verify functional equivalence regarding switch state logic and absolute maximum ratings before substituting these legacy parts.
