Product details
Overview
MAX4517CUK+T from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), CMOS analog switch optimized for low-voltage dual-supply operation. It delivers 20Ω on-resistance at ±5V, 1nA off-leakage at +25°C, and rail-to-rail signal handling across ±1V to ±6V supplies-enabling precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4517CUK+T datasheet, MAX4517CUK+T pinout, MAX4517CUK+T application, or MAX4517CUK+T equivalent, key selection criteria include guaranteed NC switching behavior, SOT23-5 package compatibility, low charge injection (20pC max), fast tOFF = 75ns, and dual-supply leakage performance across temperature.
Technical Context
The MAX4517CUK+T implements a fully differential CMOS transmission gate architecture with V+ and V− pins powering both analog switches and internal logic-level translators. Its NC configuration ensures COM-to-NC continuity when IN is low, with no internal ground reference-logic thresholds are referenced solely to V+.
ESD protection diodes connect each analog terminal (COM, NO/NC) to both V+ and V−, defining the absolute maximum analog input range and contributing to temperature-dependent leakage asymmetry. All analog leakage flows between signal pins and supply rails-not between switch terminals-supporting bidirectional signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch-COM connected to NC when control input is low. |
| On-Resistance (RON) | 20Ω max at ±5V-ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| Off-Leakage Current | 1nA max at +25°C-preserves accuracy in high-impedance sensor or sample-hold circuits. |
| Charge Injection | 20pC max-limits voltage glitch on sampled nodes, critical for ADC front-end multiplexing. |
| Switching Speed | tON = 100ns, tOFF = 75ns at ±5V-supports medium-speed signal routing without timing bottlenecks. |
| Supply Range | ±1V to ±6V dual supply-enables operation from single-cell Li-ion (±2.5V) up to industrial ±5V rails. |
| Analog Signal Range | Rail-to-rail (V− to V+)-allows full dynamic range utilization without level-shifting circuitry. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.75mm × 1.3mm), tape-and-reel compatible, rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | CMOS-compatible logic input referenced to V+; low = NC closed, high = NC open. |
| 2 - NC | Analog switch terminal (normally closed) | Internally connected to COM when IN = low; bidirectional signal path with RON = 20Ω. |
| 3 - V− | Negative supply rail | Powers analog switch core and logic; sets lower bound of analog signal range (V− to V+). |
| 4 - V+ | Positive supply rail | Powers analog switch core and logic; defines upper analog signal limit and logic threshold reference. |
| 5 - COM | Analog common terminal | Bidirectional node shared with NC (when closed); serves as input or output depending on system topology. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed NC switching behavior | Ensures fail-safe continuity in power-loss or logic-fault conditions-critical for safety-critical signal paths. |
| Low on-resistance flatness (6Ω) | Maintains consistent gain and linearity across full analog input range (±4.5V), reducing distortion in AC-coupled signals. |
| 100% tested at +25°C, correlation-guaranteed over temperature | Delivers production-ready leakage and RON specs without derating assumptions for commercial-temperature designs. |
| Low charge injection (20pC max) | Minimizes settling error in multiplexed ADC applications-reduces post-switching calibration overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4517EUK+T | Same functionality and pinout; rated for −40°C to +85°C extended temperature range. | Required for automotive cabin modules or industrial controllers operating beyond 70°C. | Select MAX4517EUK+T when ambient temperature exceeds +70°C or lifecycle validation requires extended temp qualification. |
| ADG1419BRMZ | NC SPST switch with 1.5Ω RON (at ±15V), higher supply voltage range (±5V to ±16.5V), but larger MSOP-10 package. | Used where ultra-low on-resistance dominates over board space, and higher supply voltages are present. | Choose ADG1419BRMZ only if RON <2Ω is mandatory and SOT23-5 footprint is not constrained. |
Compared with MAX4517CUK+T, the MAX4517EUK+T offers identical electrical behavior with extended thermal qualification, while ADG1419BRMZ trades package size and supply flexibility for significantly lower RON-making MAX4517CUK+T optimal for cost-sensitive, space-constrained commercial-grade portable systems.

FAQ
What is the switching configuration of the MAX4517CUK+T?
The MAX4517CUK+T is a normally closed (NC) SPST analog switch: when the IN pin is logic low (relative to V+), the COM and NC terminals are conductively connected; when IN is high, the path opens. This behavior is intrinsic to the die design and does not require external biasing-ensuring predictable default state in power-loss scenarios. The MAX4517CUK+T maintains this NC function across its full ±1V to ±6V dual-supply range.
Does the MAX4517CUK+T support single-supply operation?
The MAX4517CUK+T is specified and tested for dual-supply operation (±1V to ±6V), but it can operate with a single supply ranging from +2V to +12V. However, logic thresholds shift with V+, and TTL-level inputs may violate absolute maximum ratings above +3V. For robust single-supply use, Maxim recommends the pin-compatible MAX4514/MAX4515 instead. The MAX4517CUK+T's internal architecture relies on symmetric V+/V− rails for optimal leakage and RON performance.
What is the maximum allowable analog input voltage for the MAX4517CUK+T?
The MAX4517CUK+T supports rail-to-rail analog signals from V− to V+. With ±5V supplies, the analog input range is −5V to +5V; with ±2.5V, it is −2.5V to +2.5V. Voltages exceeding V+ or falling below V− are clamped by internal ESD diodes-limiting forward current to ±20mA. Exceeding these clamping limits risks permanent damage. The MAX4517CUK+T's absolute maximum analog terminal voltage is (V+ + 0.3V) or (V− − 0.3V), per datasheet Note 1.
How does temperature affect leakage current in the MAX4517CUK+T?
Off-leakage current in the MAX4517CUK+T increases with temperature: specified at 1nA max at +25°C and 20nA max at +85°C. This rise is due to thermally activated reverse-bias conduction in the internal ESD protection diodes connected between each analog pin and V+/V−. On-leakage follows similar behavior (2nA at +25°C, 40nA at +85°C). These values are 100% production-tested at hot temperature and correlation-guaranteed at room temperature-ensuring MAX4517CUK+T meets spec across its 0°C to +70°C operating range.
Is the MAX4517CUK+T pin-compatible with other packages in the MAX4516/MAX4517 family?
Yes-the MAX4517CUK+T in SOT23-5 shares identical pinout and function with the SO-8 (MAX4517CSA) and PDIP-8 (MAX4517CPA) variants. Pin 1 is IN, Pin 2 is NC, Pin 3 is V−, Pin 4 is V+, and Pin 5 is COM across all packages. This allows direct PCB footprint substitution between packages when thermal or layout constraints permit. The MAX4517CUK+T's marking "AH" (per datasheet) further confirms its identity as the NC variant within the family.
