MAX4554CSE

Analog Switches - Special Purpose Overview

The MAX4554CSE is a CMOS analog IC configured as a force-sense switch for Kelvin sensing in automated test equipment. It contains two high-current, low-resistance force switches and two higher resistance sense/guard switches, arranged as two triple-pole/single-throw (3PST) normally open switches. The device operates from single supplies of +9V to +40V or dual supplies of ±4.5V to ±20V. Force signal paths exhibit a maximum on-resistance of 6Ω with matching to 1Ω max. Sense-guard paths have a maximum on-resistance of 60Ω with matching to 8Ω max. Switching times are typically 275ns at ±15V supplies. Power consumption is low at 1µA. Digital inputs feature TTL/CMOS-compatible thresholds.

Analog Switches - Special Purpose Feature Summary

• Kelvin sensing architecture with separate high-current force and high-impedance sense paths
• Rail-to-Rail analog signal handling capability across the full supply range
• TTL and CMOS logic input compatibility ensuring broad interface flexibility
• Low power consumption suitable for battery-operated or energy-efficient systems

Analog Switches - Special Purpose Applications

• Automated Test Equipment (ATE)
• Precision Calibrators
• Automatic Calibration Circuits
• Asymmetric Digital Subscriber Line (ADSL) with Loopback

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix CSE indicates the narrow SOIC package and commercial temperature range against the official datasheet ordering information. Confirm that the component meets current environmental compliance standards required for the target assembly process. Ensure the source documentation matches the manufacturer's latest revision to avoid discrepancies in pin definitions or electrical limits.

Analog Switches - Special Purpose Selection Notes

Select this component when precise four-wire Kelvin measurements are required in ATE environments. The distinct separation between force and sense switches minimizes voltage drop errors caused by conductor resistance. Verify that the ±15V supply configuration aligns with the system's available power rails and that the 275ns switching speed meets the timing requirements of the test sequence.

Analog Switches - Special Purpose Part Context

The MAX4554 belongs to a family of force-sense switches that includes the MAX4555 and MAX4556. While the MAX4554 provides two 3PST switches, the MAX4555 offers four SPST switches and the MAX4556 provides three SPDT switches. All variants share similar electrical characteristics regarding on-resistance and leakage but differ in channel count and switch configuration topology.
