Analog Devices Inc./Maxim Integrated MAX4517EUK-T

Overview

MAX4517EUK-T from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), dual-supply CMOS analog switch with 20Ω on-resistance at ±5V, 1nA off-leakage at +25°C, and rail-to-rail signal handling capability-designed for low-voltage audio routing and battery-powered data-acquisition systems.

For engineers reviewing the MAX4517EUK-T datasheet, MAX4517EUK-T pinout, MAX4517EUK-T application, or MAX4517EUK-T equivalent, key selection criteria include guaranteed NC configuration, SOT23-5 package compatibility, ±1V to ±6V dual-supply operation, and sub-100ns switching performance in portable communications circuits.

Technical Context

The MAX4517EUK-T implements a fully differential CMOS transmission gate architecture with separate V+ and V− supply pins driving both analog signal paths and internal logic translators. Its digital input is referenced to V+, enabling CMOS-compatible control across the full ±5V supply range.

It features internally disconnected (N.C.) pins in SOT23-5 packaging, no ground reference, and ESD protection diodes clamped between each analog terminal and both supplies-making leakage current highly dependent on analog signal voltage relative to V+ and V−.

Key Specifications

Pinout & Package

SOT23-5 surface-mount package with 1.3mm × 2.9mm footprint, 0.95mm height, and gull-wing leads; pin 1 marked with dot or bevel; tape-and-reel compatible per EIA-481-1 standard.

FAQ

What is the default state of the MAX4517EUK-T switch?

The MAX4517EUK-T is a normally closed (NC) analog switch: it conducts between COM and NC terminals when the IN pin is logic LOW (≤1.5V relative to V+). When IN is driven HIGH (≥3.5V relative to V+), the switch opens. This fail-safe behavior ensures signal continuity during power-up, reset, or control loss-making MAX4517EUK-T ideal for critical signal paths where interruption must be actively commanded.

Can the MAX4517EUK-T operate from a single supply?

The MAX4517EUK-T is designed for dual-supply operation (±1V to ±6V) and does not include an internal ground reference. While it may function with a single-ended supply (e.g., V+ = +5V, V− = 0V), its logic thresholds and analog range become asymmetric, and leakage increases significantly. For true single-supply applications, Maxim recommends the pin-compatible MAX4514/MAX4515 series instead of MAX4517EUK-T.

What is the maximum analog signal voltage the MAX4517EUK-T can handle?

The MAX4517EUK-T supports rail-to-rail analog signals-from V− to V+. With ±5V supplies, this means signals from –5V to +5V are fully passed without clipping or distortion. Exceeding V+ or V− on any analog pin activates internal ESD diodes, limiting absolute input to (V− – 0.3V) to (V+ + 0.3V) per Absolute Maximum Ratings-so the usable analog range remains strictly bounded by the applied supplies, not external rails.

How does temperature affect the on-resistance of the MAX4517EUK-T?

The MAX4517EUK-T exhibits moderate RON variation over temperature: typical on-resistance rises from ~12Ω at –40°C to ~25Ω at +85°C under ±5V conditions. The datasheet guarantees ≤20Ω across –40°C to +85°C, meaning worst-case design margin remains within specification. This predictable monotonic increase simplifies gain-error compensation in precision multiplexer designs using MAX4517EUK-T.

Is the SOT23-5 package of the MAX4517EUK-T RoHS-compliant and lead-free?

Yes, the MAX4517EUK-T is manufactured in a RoHS-compliant, lead-free SOT23-5 package per Maxim's standard product release. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 rating and is qualified for reflow soldering up to 260°C peak. Full compliance documentation-including substance declarations and test reports-is available through Analog Devices' product page for MAX4517EUK-T.
