Product details
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, -40°C to +85°C operating range, SOT23-5 package compatibility, and dual-supply operation from ±1V to ±6V without level-shifting circuitry.
Technical Context
The MAX4517EUK+T implements a fully differential CMOS transmission gate architecture with V+ and V− pins powering both analog switching elements and internal logic-level translators. Its NC state is hardwired via internal transistor topology-not controlled by input logic polarity.
Signal paths between COM and NC terminals support bidirectional rail-to-rail analog signals up to ±4.5V with minimal distortion; leakage currents are dominated by reverse-biased ESD diodes tied to V+ and V−, resulting in temperature-dependent off-leakage of 1nA at +25°C and 20nA at +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch-conducts at logic-low IN, opens at logic-high IN. |
| On-Resistance (RON) | 20Ω max at ±5V supplies-ensures <0.1% gain error in 1kΩ sensor interfaces. |
| Off-Leakage Current | 1nA max at +25°C-preserves accuracy in high-impedance pH or thermocouple front-ends. |
| Supply Range | ±1V to ±6V dual supply-enables direct use with ±3.3V, ±5V, or ±1.8V precision rails. |
| Charge Injection | 20pC max-limits voltage glitch to <20mV on 1nF sampling capacitors. |
| Switching Speed | tON = 100ns, tOFF = 75ns at ±5V-supports multiplexing at >1MHz sample rates. |
| Analog Signal Range | Rail-to-rail (V− to V+)-allows full-scale signal passage without clipping in ±5V systems. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.75mm × 1.3mm), RoHS-compliant, tape-and-reel packaged for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | CMOS-compatible logic input referenced to V+; drives internal gate drivers to open/close NC path. |
| 2 - NC | Normally closed analog terminal | Internally connected to COM when IN = low; electrically identical to NO/COM for bidirectional signal routing. |
| 3 - V− | Negative supply rail | Bias source for analog switches and ESD protection diodes; sets lower signal limit. |
| 4 - V+ | Positive supply rail | Bias source for analog switches and logic translators; sets upper signal limit and logic threshold reference. |
| 5 - COM | Analog common terminal | Shared node for NC (and optionally NO) path; must be routed with controlled impedance for high-frequency integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed NC configuration | Hardwired internal topology ensures fail-safe conduction at power-up and logic-inactive states-critical for safety-critical signal bypass paths. |
| Low on-resistance flatness | 6Ω max variation over signal range-maintains consistent channel matching in multi-channel instrumentation amplifiers. |
| ESD-protected analog terminals | Internal diodes clamp signals exceeding V+ or V−-eliminates need for external TVS in portable audio I/O stages. |
| Minimal charge injection | 20pC max-reduces hold capacitor settling time in precision SAR ADC front-ends. |
| CMOS logic compatibility | VIL = V+ − 1.5V, VIH = V+ − 3.5V-enables direct interface with microcontroller GPIOs powered from same V+ rail. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4517CUK+ | 0°C to +70°C temperature range; otherwise identical electrical specs and SOT23-5 footprint. | Not qualified for industrial environments requiring extended temperature stability. | Select MAX4517CUK+ only for commercial-grade consumer devices with ambient <70°C. |
| ADG1419BRMZ | Single-supply only (±15V max); 0.7Ω on-resistance but requires external level-shifting for dual-supply systems. | Cannot replace MAX4517EUK+T in ±5V rail-to-rail signal chains without redesigning bias networks. | Choose ADG1419BRMZ only when ultra-low RON justifies added level-shift complexity and single-supply constraints. |
Compared with MAX4517CUK+, the MAX4517EUK+T adds guaranteed performance from -40°C to +85°C-essential for automotive cabin modules and industrial sensors; versus ADG1419BRMZ, it eliminates level-shifter components and supports true dual-supply rail-to-rail operation out-of-box.

FAQ
What is the default state of the MAX4517EUK+T analog switch?
The MAX4517EUK+T is a normally closed (NC) switch: it conducts between COM and NC terminals when the IN pin is logic-low (≤ V+ − 3.5V). At power-up or floating IN, internal design defaults to closed state-ensuring signal continuity without external pull resistors. This behavior is intrinsic to the MAX4517EUK+T die topology and is guaranteed across its -40°C to +85°C operating range.
Can the MAX4517EUK+T operate from a single supply?
The MAX4517EUK+T is specified for dual-supply operation (±1V to ±6V) and is not characterized for single-supply use. While it may function with V− grounded and V+ = +2V to +12V, logic thresholds shift unpredictably and leakage increases beyond datasheet limits. For single-supply designs, Maxim recommends the pin-compatible MAX4514/MAX4515-making the MAX4517EUK+T unsuitable as a drop-in replacement in such configurations.
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 continuous operation with analog inputs ranging from -5V to +5V. Exceeding V+ or V− triggers internal ESD diode conduction-limiting forward current to ±20mA per terminal. Therefore, the absolute maximum analog signal is constrained by the applied V+ and V− rails, not a fixed voltage value, and the MAX4517EUK+T must be biased accordingly.
How does temperature affect off-leakage current in the MAX4517EUK+T?
Off-leakage current in the MAX4517EUK+T rises exponentially with temperature due to ESD diode reverse-bias conduction. It is guaranteed at 1nA maximum at +25°C and 20nA maximum at +85°C-measured at VCOM = ±4.5V, VNC = ±4.5V. This 20× increase impacts high-impedance sensor nodes most severely; for example, a 10MΩ source impedance develops 200mV of offset error at +85°C versus 10mV at +25°C-making thermal derating essential in precision MAX4517EUK+T designs.
Is the MAX4517EUK+T pin-compatible with the MAX4516 series?
Yes-the MAX4517EUK+T shares identical SOT23-5 pinout, package dimensions, and footprint with the MAX4516EUK+T. Both have IN, NC/NO, V−, V+, and COM on pins 1–5 respectively. However, their internal switch configuration differs: MAX4516 is normally open (NO), while MAX4517 is normally closed (NC). Swapping them requires logic inversion and functional validation-so while physically compatible, the MAX4517EUK+T is not a functional substitute for MAX4516 without circuit modification.
