Product details
Overview
MAX4569EUK-T from Maxim Integrated is a ±15kV ESD-protected, single-pole/single-throw (SPST), normally closed (NC) analog switch operating from +1.8V to +12V. It features 70Ω on-resistance at +5V, 2Ω max on-resistance match between channels, and rail-to-rail signal handling - enabling precision low-voltage audio routing in battery-powered medical sensors.
For engineers reviewing the MAX4569EUK-T datasheet, MAX4569EUK-T pinout, MAX4569EUK-T application, or MAX4569EUK-T equivalent, key selection criteria include guaranteed off-leakage ≤5nA at +85°C, 5-pin SOT23 package compatibility with MAX4515, and ESD robustness for handheld test equipment interfaces.
Technical Context
The MAX4569EUK-T implements a CMOS transmission-gate architecture with integrated bidirectional SCRs on NC and COM terminals for ±15kV IEC 1000-4-2 air-gap ESD protection. Its logic input thresholds (+0.8V/–2.4V) ensure TTL/CMOS compatibility with +5V supplies, and internal diode clamping prevents latchup during supply sequencing transients.
Unlike the MAX4561 SPDT variant, the MAX4569EUK-T lacks break-before-make timing and supports only NC-closed operation - requiring external control logic to manage signal path continuity during switching. On-resistance flatness remains ≤4Ω over 0V to V+ signal range, critical for low-distortion audio channel selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 70Ω at +5V supply - ensures <0.1% gain error in 10kΩ impedance audio paths |
| On-Resistance Match | ≤2Ω max - enables matched-channel applications like differential signal routing |
| Off-Leakage Current | ≤5nA at +85°C - preserves accuracy in high-impedance sample-and-hold circuits |
| ESD Protection | ±15kV HBM & IEC 1000-4-2 air-gap - eliminates need for external TVS on NC terminal |
| Signal Range | Rail-to-rail - supports full 0V to +5V analog swing without clipping |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees reliable switching with 3.3V or 5V microcontroller GPIO |
| Turn-On Time | 180ns max - suitable for <5MHz multiplexed data acquisition sampling |
Pinout & Package
MAX4569EUK-T is housed in a RoHS-compliant 5-pin SOT23 package (package code U5+2), with 1.3mm × 0.8mm footprint and 0.95mm height - compatible with standard automated pick-and-place assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Active-low logic control input - drives internal gate to open NC path when pulled low |
| 2 | V+ | Positive supply rail - must be decoupled with ≥0.1µF capacitor to GND for ESD immunity |
| 3 | GND | Analog/digital ground reference - shared return for ESD SCR current paths |
| 4 | NC | Normally closed analog terminal - conducts to COM when IN = low; isolated when IN = high |
| 5 | COM | Common analog node - connects to system signal chain; protected to ±2.5kV ESD |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance flatness | ≤4Ω variation across 0V to V+ signal range - minimizes THD in audio paths |
| Low charge injection | 6pC typical - reduces glitch amplitude in precision sample-and-hold front-ends |
| Break-before-make not required | NC-only topology eliminates timing-critical path interruption - simplifies control logic |
| Industry-standard pinout | Pins 1–5 match MAX4515 footprint - enables drop-in replacement without PCB rework |
| ESD-protected COM terminal | ±2.5kV per IEC 3015.7 - safeguards signal integrity in connector-facing positions |
Applications
| Portable ECG Monitor Front-End | Battery-Powered Oscilloscope Probe Selector |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4515EUK+T | Identical 5-pin SOT23 footprint and NC function; same ±15kV ESD rating but 100Ω RON at +5V | Higher on-resistance limits use in <100kΩ impedance paths | Select MAX4515EUK+T only if cost sensitivity outweighs on-resistance performance requirements |
| TMUX1574DSGR | 4-channel SPST, 5.5Ω RON, but no integrated ±15kV ESD protection - requires external TVS diodes | Requires additional board area and BOM count for ESD hardening | Choose TMUX1574DSGR only when multi-channel integration and ultra-low RON justify added design complexity |
Compared with MAX4569EUK-T, MAX4515EUK+T trades 30Ω higher on-resistance for identical ESD robustness and footprint, while TMUX1574DSGR offers lower resistance but shifts ESD protection burden to external components - making MAX4569EUK-T optimal for space-constrained, high-reliability single-channel routing.

FAQ
What is the maximum supply voltage rating for MAX4569EUK-T?
The MAX4569EUK-T supports a single-supply range from +1.8V to +12V, with an absolute maximum rating of +13V on the V+ pin relative to GND. Operation near +12V requires a minimum 0.1µF bypass capacitor from V+ to GND placed adjacent to the device to maintain ESD immunity and prevent supply rail disturbance during SCR conduction events. Exceeding +13V risks permanent damage.
Does MAX4569EUK-T support rail-to-rail analog signal switching?
Yes, the MAX4569EUK-T fully supports rail-to-rail analog signal handling - meaning it can pass signals from 0V up to the V+ supply voltage without clipping or distortion. This capability is enabled by its CMOS transmission-gate architecture and verified across the full -40°C to +85°C operating temperature range, making it suitable for interfacing with modern low-voltage ADCs and DACs that utilize the entire supply rail.
How does the ESD protection on MAX4569EUK-T differ between NC and COM pins?
The NC pin of the MAX4569EUK-T is rated for ±15kV ESD per IEC 1000-4-2 air-gap discharge, implemented via on-chip bidirectional SCRs. In contrast, the COM pin is rated for ±2.5kV per IEC 3015.7 - protected by internal diode clamps rather than SCRs. This asymmetry reflects the NC pin's exposure to external connectors and user handling, while COM typically interfaces internally to downstream circuitry, requiring less stringent protection.
Can MAX4569EUK-T be used with a +3.3V logic controller?
Yes, the MAX4569EUK-T accepts +3.3V logic levels directly: its input logic low threshold is +0.6V (min) and logic high threshold is +2.0V (min) when operating from a +3V supply, comfortably accommodating standard 3.3V CMOS outputs. No level-shifting circuitry is needed, and the device draws only 1µA typical input leakage current - preserving battery life in always-on portable systems using the MAX4569EUK-T.
What is the guaranteed on-resistance match specification for MAX4569EUK-T?
The MAX4569EUK-T guarantees on-resistance match between units of ≤2Ω maximum, measured under conditions of V+ = +4.5V, ICOM = 1mA, and analog voltage at NO/NC = 1V or 3.5V across the full -40°C to +85°C temperature range. This tight matching ensures consistent gain and phase response when multiple MAX4569EUK-T devices are used in parallel or cascaded configurations within precision analog signal chains.
