MAX4554CSE+T

Analog Switches - Special Purpose Overview

The MAX4554CSE+T is a CMOS analog switch IC configured for Kelvin sensing in automated test equipment. It contains two triple-pole/single-throw (3PST) normally open switches, each comprising one high-current force path, one sense path, and one guard path. The device operates from single supplies of +9V to +40V or dual supplies of ±4.5V to ±20V. Force switches feature a maximum on-resistance of 6Ω with 1Ω matching, while sense/guard switches have a maximum on-resistance of 60Ω with 8Ω matching. Switching times are typically 275ns at ±15V supplies, with power consumption limited to 1µA.

Analog Switches - Special Purpose Feature Summary

• Integrated force-sense architecture enabling precise Kelvin sensing by separating high-current forcing paths from low-leakage voltage sensing paths.
• Rail-to-Rail signal handling capability allowing analog signals to span the full supply range without distortion.
• TTL and CMOS compatible digital inputs with defined logic thresholds ensuring reliable interface with standard logic families.

Analog Switches - Special Purpose Applications

• Automated Test Equipment (ATE)
• Precision Calibrators
• Automatic Calibration Circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range and narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for the absolute maximum ratings regarding continuous current into force terminals versus other terminals to prevent device damage during operation.

Analog Switches - Special Purpose Selection Notes

Select this component when Kelvin sensing is required to eliminate lead resistance errors in precision measurements. Compare against MAX4555 and MAX4556 if different switch configurations such as SPST NC or SPDT are needed. Verify that the ±15V supply environment matches the typical performance specifications for on-resistance and switching times provided in the datasheet.

Analog Switches - Special Purpose Part Context

The MAX4554 belongs to the Maxim Integrated MAX4554/MAX4555/MAX4556 family of force-sense switches. These devices are specifically engineered for applications requiring high accuracy in voltage sourcing and measurement where conductor resistance would otherwise degrade signal integrity. The CSE variant denotes the commercial grade operating within the 0°C to +70°C temperature range.

Analog Switches - Special Purpose Replacement Considerations

MAX4554CPE is the plastic DIP equivalent. MAX4554ESE is the -40°C to +85°C extended temperature version in the same package. MAX4555 and MAX4556 offer alternative internal switch topologies but share similar electrical characteristics and pinouts.
