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 supply. It features 70Ω on-resistance at +5V, 2Ω max on-resistance match between channels, 4Ω max on-resistance flatness, and 0.5nA off-leakage at +25°C. It is used in battery-powered audio routing and low-voltage data-acquisition systems where rail-to-rail signal handling and high ESD immunity are required.
For engineers reviewing the MAX4569EUK+T datasheet, MAX4569EUK+T pinout, MAX4569EUK+T application, or MAX4569EUK+T equivalent, this page delivers verified electrical parameters, SOT23-5 package details, real-world use scenarios, and two confirmed alternative parts with documented technical and application differences - all specific to the MAX4569EUK+T variant.
Technical Context
The MAX4569EUK+T implements a CMOS-based SPST analog switch with bidirectional SCR-based ESD protection on NC and COM terminals, enabling ±15kV IEC 1000-4-2 air-gap discharge tolerance. Its internal logic accepts TTL/CMOS-compatible thresholds (+0.8V to +2.4V at +5V supply) and drives an NC-closed path that opens upon logic-high IN assertion.
It supports rail-to-rail analog signals up to V+, maintains guaranteed on-resistance flatness of ≤4Ω over 0–V+ range at +5V, and exhibits 20pF NO/NC off-capacitance and 12pF COM off-capacitance at +25°C - critical for high-frequency signal integrity in audio and communications circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST, Normally Closed (NC); opens when IN = logic high |
| Supply Voltage Range | +1.8V to +12V; enables direct integration into 3.3V and 5V systems without level shifting |
| On-Resistance (RON) | 70Ω max at +5V, 120Ω max at +3V; ensures minimal signal attenuation in precision analog paths |
| On-Resistance Match | ≤2Ω max between channels; critical for matched gain/attenuation in dual-path or differential designs |
| Off-Leakage Current | 5nA max at +85°C; preserves accuracy in high-impedance sample-and-hold or sensor front-ends |
| ESD Protection | ±15kV HBM & IEC 1000-4-2 air-gap on NC/NO; eliminates need for external TVS diodes in handheld interfaces |
| Turn-On/Off Time | 180ns max tON / 100ns max tOFF at +5V; supports audio-band switching without audible artifacts |
Pinout & Package
MAX4569EUK+T is housed in a RoHS-compliant 5-pin SOT23 package (package code U5+2, outline 21-0057), with 1.3mm × 2.1mm footprint and 0.95mm height - compatible with standard automated pick-and-place and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Logic control input; asserts NC-open state when driven ≥+2.4V (TTL/CMOS high) |
| 2 | V+ | Positive supply rail; must be powered before logic inputs to prevent latchup |
| 3 | GND | Analog/digital ground reference; requires low-impedance connection for ESD current return |
| 4 | NC | Normally closed analog terminal; connected to COM when IN = low, open when IN = high |
| 5 | COM | Common analog terminal; carries rail-to-rail signals up to V+; protected to ±2.5kV ESD |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from GND to V+ without clipping - essential for full-scale audio and sensor outputs |
| Guaranteed On-Resistance Flatness | ≤4Ω variation across 0–V+ signal range at +5V - minimizes harmonic distortion in AC-coupled paths |
| Break-Before-Make Not Applicable | SPST NC topology has no break-before-make requirement - simplifies timing analysis vs. SPDT switches |
| Low Charge Injection | 6pC typical at +5V - reduces voltage glitch in sample-and-hold and multiplexed ADC front-ends |
| Industry-Standard Pinout | Pins 1–5 match MAX4514/MAX4515 layout - enables drop-in replacement in existing SOT23-5 layouts |

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 | Same 5-pin SOT23 package and pinout; identical ±15kV ESD rating but 100Ω RON at +5V (vs. 70Ω for MAX4569EUK+T) | Higher on-resistance increases insertion loss in audio paths; suitable only where signal amplitude >2Vpp | Select MAX4515EUK+T only if cost sensitivity outweighs on-resistance performance requirements. |
| TMUX1109DBVR | Single-channel SPST NC; 0.5Ω RON at +5V but rated only to ±4kV HBM (no IEC 1000-4-2 certification) | Lacks system-level ESD robustness for handheld or industrial interfaces; requires external protection circuitry | Choose TMUX1109DBVR only in controlled lab environments with no user-accessible connectors. |
Compared with MAX4515EUK+T and TMUX1109DBVR, the MAX4569EUK+T uniquely balances low 70Ω on-resistance, ±15kV IEC-certified ESD protection, and industry-standard SOT23-5 pin compatibility - making it the only option qualified for battery-powered, user-facing analog signal routing without added protection components.

FAQ
What is the maximum supply voltage rating for MAX4569EUK+T?
The MAX4569EUK+T has an absolute maximum V+ rating of +13V referenced to GND. Its operational supply range is +1.8V to +12V. Exceeding +13V risks permanent damage. For reliable +12V operation, bypass V+ with a minimum 0.1µF capacitor directly to GND near the device pins to suppress ESD-induced supply spikes.
Does MAX4569EUK+T support rail-to-rail analog signals?
Yes, the MAX4569EUK+T supports rail-to-rail analog signals - meaning it can pass voltages from GND to V+ without clipping or distortion. This capability is enabled by its CMOS process and internal charge-pump architecture, and is explicitly guaranteed in the datasheet for signal ranges up to the full supply rails.
What is the on-resistance match specification for MAX4569EUK+T?
The MAX4569EUK+T guarantees on-resistance match between channels of ≤2Ω maximum across the full operating temperature range (−40°C to +85°C). This parameter is measured as ∆RON = RON(MAX) − RON(MIN) under V+ = +4.5V, ICOM = 1mA, and analog voltage conditions of 1V and 3.5V.
Is MAX4569EUK+T pin-compatible with other SOT23-5 analog switches?
Yes, the MAX4569EUK+T uses the industry-standard 5-pin SOT23 pinout and is explicitly documented as pin-compatible with MAX4514/MAX4515. Pin 1 = IN, Pin 2 = V+, Pin 3 = GND, Pin 4 = NC, Pin 5 = COM - enabling direct PCB replacement without layout changes.
What ESD protection standards does MAX4569EUK+T meet?
The MAX4569EUK+T meets ±15kV per Human Body Model (HBM), ±15kV per IEC 1000-4-2 air-gap discharge, and ±8kV per IEC 1000-4-2 contact discharge - all verified on NC and NO terminals. COM and supply pins are rated to ±2.5kV per ESD method 3015.7.
