Product details
Overview
MAX4611ESD+ from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with normally closed (NC) configuration, 14-pin narrow SO package, 100Ω max on-resistance at +5V supply, <2nA off-leakage at +85°C, and rail-to-rail signal handling from GND to V+. It routes audio/video signals and enables sample-and-hold functions in battery-powered instrumentation.
For engineers reviewing the MAX4611ESD+ datasheet, MAX4611ESD+ pinout, MAX4611ESD+ application, or MAX4611ESD+ equivalent, key selection criteria include NC switch topology, guaranteed channel matching (≤4Ω), flat on-resistance over signal range, TTL/CMOS logic compatibility at +5V, and automotive-grade temperature support (-40°C to +85°C).
Technical Context
The MAX4611ESD+ implements four independent NC analog switches controlled by active-low digital inputs (IN1–IN4), each connecting COMx to NCx when input is logic low. Its CMOS transmission-gate architecture ensures symmetrical conduction and bidirectional signal flow across the full analog range (GND to V+).
It operates from a single +2V to +12V supply, with logic thresholds fixed at +0.8V (VIL) and +2.4V (VIH) for +5V operation-guaranteeing interoperability with standard TTL and CMOS drivers without level shifting. Internal ESD protection exceeds 2kV per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - COM connects to NC when IN = LOW |
| On-Resistance (max) | 100Ω at +5V supply - limits voltage drop and power loss in signal path |
| On-Resistance Match | ≤4Ω between channels - ensures consistent gain/attenuation across multiplexed paths |
| Off-Leakage Current | <2nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor interfaces |
| Analog Signal Range | Rail-to-rail (GND to V+) - supports full-scale signal switching without clipping |
| Logic Compatibility | TTL/CMOS at +5V - accepts standard 0.8V/2.4V thresholds without external biasing |
| Supply Voltage Range | +2V to +12V - enables use in both low-power portable and industrial +12V systems |
Pinout & Package
MAX4611ESD+ uses a 14-pin narrow SO (Small Outline) package with exposed pad not present (QFN variant has EP; SO does not). Pin 7 is GND; pins 13, 5, 6, 12 are digital inputs IN1–IN4; pins 2, 4, 9, 10 are common terminals COM1–COM4; pins 1, 3, 8, 11 are NC terminals NC1–NC4; pin 14 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pin 14) | Positive supply input | Powers analog and digital sections; must be applied before signals to prevent latch-up |
| GND (Pin 7) | Ground reference | Digital and analog return; requires low-impedance connection to minimize noise coupling |
| IN1–IN4 (Pins 13,5,6,12) | Digital control inputs | Active-low logic: LOW connects COMx to NCx; HIGH disconnects (open-circuit state) |
| COM1–COM4 (Pins 2,4,9,10) | Common analog terminals | Bidirectional signal ports - connect to source/load; tolerate GND to V+ voltage swing |
| NC1–NC4 (Pins 1,3,8,11) | Normally closed analog terminals | Default-connected to COM when INx = LOW; floating when INx = HIGH |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without distortion or clipping - critical for precision DC-coupled routing |
| Guaranteed on-resistance flatness | ≤18Ω variation over full signal range - maintains linearity in audio and data-acquisition paths |
| Channel-to-channel on-resistance match | ≤4Ω max mismatch - enables accurate ratio-metric measurements in multi-channel systems |
| High ESD robustness | >2kV per Method 3015.7 - reduces field failure risk in handling and end-equipment integration |
| Low off-leakage current | <2nA at +85°C - minimizes error in high-Z sample-and-hold and sensor front-ends |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611EUD+ | Same IC die, 14-pin TSSOP package - 5mm × 4.4mm vs. SO's 8.65mm × 3.9mm footprint | Preferred for space-constrained PCBs; thermal resistance higher than SO | Select for compact layouts where reflow profile supports fine-pitch TSSOP |
| ADG1411BRZ | Quad NC switch, 16-pin SOIC; 1.5Ω typical RON, but 16V abs max rating and higher 125Ω max RON at +5V | Better RON flatness (1.5Ω), wider supply range (+5V to ±15V), but larger package and no automotive temp grade | Choose when ultra-low on-resistance variation is required and +125°C operation is unnecessary |
Compared with MAX4611ESD+, MAX4611EUD+ offers identical electrical performance in a smaller footprint but reduced thermal margin, while ADG1411BRZ provides lower on-resistance flatness and broader supply flexibility at the cost of larger size and absence of extended temperature qualification.

FAQ
What is the maximum supply voltage for MAX4611ESD+?
The absolute maximum supply voltage (V+) for MAX4611ESD+ is +13V referenced to GND. Operation above +12V is possible but requires careful bypassing with ≥0.1µF ceramic capacitor near the V+ pin and attention to voltage tolerances - especially in ±12V systems where overshoot may exceed 13.0V differential limit. The device is fully specified from +2V to +12V.
Does MAX4611ESD+ support rail-to-rail analog signal switching?
Yes, MAX4611ESD+ supports true rail-to-rail analog signal switching: its COM and NC terminals handle voltages from GND to V+ without degradation. This capability is enabled by its CMOS transmission-gate design and is guaranteed across the full operating temperature range (-40°C to +85°C) and supply range (+2V to +12V).
What is the logic polarity of the control inputs on MAX4611ESD+?
The control inputs (IN1–IN4) on MAX4611ESD+ are active-low: a logic LOW (≤0.8V) closes the switch (connects COMx to NCx), and a logic HIGH (≥2.4V at +5V supply) opens it. This NC topology means the switch defaults to closed when control is un-driven or held LOW - a key safety feature in fail-safe signal routing.
How does MAX4611ESD+ compare to the industry-standard 74HC4066?
MAX4611ESD+ is pin-compatible with the 74HC4066 but improves on it with lower on-resistance (100Ω vs. ~120Ω typical), tighter channel matching (≤4Ω vs. unspecified), guaranteed flatness (≤18Ω), and enhanced ESD protection (>2kV vs. ~200V). It also features rail-to-rail signal handling and is qualified for -40°C to +85°C operation, unlike most HC4066 variants.
Is MAX4611ESD+ suitable for audio-frequency signal routing?
Yes, MAX4611ESD+ is well-suited for audio routing: it delivers -80dB crosstalk and -60dB off-isolation at 1MHz, 300MHz on-channel bandwidth, and 0.009% THD+N at 2VP-P (600Ω load, 20Hz–20kHz). Its low 100Ω RON and flatness preserve frequency response, while <2nA leakage prevents audible pop/click in DC-coupled paths.
