Product details
Overview
MAX4665ESE+ from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, 5Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±10V. It delivers matched on-resistance (≤0.5Ω), flat on-resistance (≤0.5Ω), and <5nA off-leakage at +85°C - ideal for precision audio routing and automated test equipment where low distortion and high reliability replace mechanical relays.
For engineers reviewing the MAX4665ESE+ datasheet, MAX4665ESE+ pinout, MAX4665ESE+ application, or MAX4665ESE+ equivalent, key selection criteria include guaranteed RON matching across all four switches, TTL/CMOS-compatible logic thresholds (+0.8V / +2.4V), break-before-make timing (only in MAX4666), and SOIC-16 packaging with industrial temperature range (–40°C to +85°C).
Technical Context
The MAX4665ESE+ implements CMOS-based SPST switching architecture with independent control of each NO channel via dedicated digital inputs (IN1–IN4). Its analog path supports rail-to-rail signals across the full supply range, with internal protection diodes clamping inputs exceeding V+ or V−.
All four switches share common analog supply pins (V+, V−, GND) and logic supply (VL), enabling synchronized operation under dual- or single-supply bias. Input logic thresholds are fixed at +0.8V (low) and +2.4V (high), ensuring compatibility with TTL/CMOS drivers without level-shifting when operating from ±15V or +12V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in low-level analog paths (e.g., sensor interfaces or audio lines). |
| RON match between channels | 0.5Ω max - critical for multi-channel signal routing where gain/phase tracking matters (e.g., differential pair switching). |
| RON flatness over signal range | 0.5Ω max - maintains consistent insertion loss across ±10V analog input swing, reducing harmonic distortion. |
| Off-leakage current | 5nA max at +85°C - preserves accuracy in high-impedance circuits (e.g., precision ADC front-ends or sample-hold stages). |
| Supply range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide-range industrial and avionics power architectures without external regulators. |
| Logic input thresholds | +0.8V (low), +2.4V (high) - guarantees direct interface with standard 5V TTL/CMOS controllers without pull-ups or level shifters. |
| Turn-on/turn-off time | 130ns / 90ns typical (dual supply) - enables fast multiplexing in data acquisition systems sampling at ≥1MHz. |
Pinout & Package
MAX4665ESE+ uses a 16-pin narrow SOIC (SOICN) package with 1.27mm pitch, rated for –40°C to +85°C operation. Pin layout follows industry-standard SOIC-16 footprint with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-high logic turns corresponding NO switch ON; inverted logic sense applies only to MAX4664. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load; each pairs exclusively with its NO terminal. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - conduct only when respective INx = high; no NC terminals present. |
| 4 | V− | Negative analog supply - tied to GND for single-supply use; must be powered before logic inputs per sequencing guidelines. |
| 5 | GND | Digital/analog ground reference - shared return for logic and analog sections; requires low-impedance PCB connection. |
| 12 | VL | Logic supply input - accepts +2.7V to +5.5V; decoupling capacitor required near pin to suppress switching noise. |
| 13 | V+ | Positive analog supply - defines upper rail for analog signal range; must be powered first in dual-supply sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from V− to V+, enabling full utilization of supply rails in ±15V or +12V systems without clipping. |
| Guaranteed RON match and flatness | 0.5Ω max matching and flatness ensure uniform gain and phase response across all four channels in multi-path applications. |
| TTL/CMOS-compatible logic inputs | Fixed +0.8V/+2.4V thresholds eliminate need for external level translation when interfacing with microcontrollers or FPGAs. |
| ESD protection >2kV (HBM) | Robust input protection allows safe handling and board-level integration without additional transient suppression components. |
| Low charge injection (25pC typ) | Minimizes voltage glitches at COM nodes during switching - essential for sample-and-hold and precision DAC output routing. |
Applications
| Audio-Signal Routing | Automatic Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | 4-channel SPST, 1.8Ω RON, ±15V/12V supply, 16-TSSOP package | Lower RON but higher cost; lacks guaranteed RON match spec (typical only) | Select when ultra-low on-resistance is prioritized over channel matching or cost sensitivity. |
| TS5A3157DCKR | Single SPDT, 0.75Ω RON, +1.65V to +5.5V supply, SC70-6 package | Single-channel, lower voltage rating, smaller footprint - not functionally equivalent for quad routing | Choose only for space-constrained, low-voltage (<6V) designs requiring minimal RON, not for industrial quad-switch replacement. |
Compared with ADG1414BRUZ and TS5A3157DCKR, the MAX4665ESE+ uniquely combines guaranteed 0.5Ω RON matching, industrial temperature range, and quad NO topology in SOIC-16 - making it optimal for precision multi-channel routing where consistency and ruggedness outweigh raw RON minimization.

FAQ
What is the maximum analog signal voltage range supported by the MAX4665ESE+?
The MAX4665ESE+ supports rail-to-rail analog signals from V− to V+. With ±15V dual supplies, this enables ±10V signal handling; with +12V single supply, it supports 0V to +10V. Absolute maximum ratings allow V+ up to +44V and V− down to –44V, but operational signal range remains bounded by supply rails.
Does the MAX4665ESE+ require external protection diodes for overvoltage tolerance?
No - the MAX4665ESE+ includes internal protection diodes on all analog pins (COM, NO, V+, V−). However, if supply sequencing cannot guarantee V+ powers first, external series diodes (e.g., 1N4148) on V+ and V− are recommended to prevent latch-up, though they reduce usable analog range by ~0.7V per rail.
Can the MAX4665ESE+ operate from a single +5V supply?
No - the MAX4665ESE+ minimum single-supply voltage is +4.5V, and its logic thresholds (+0.8V / +2.4V) require VL ≥ +2.7V. While +5V meets voltage specs, performance degrades: RON rises to ~8Ω max, and off-leakage increases. For +5V systems, consider the MAX4617 or similar low-voltage optimized switches.
How does the MAX4665ESE+ differ from the MAX4664ESE+ and MAX4666ESE+?
The MAX4665ESE+ has four normally open (NO) switches; the MAX4664ESE+ has four normally closed (NC); the MAX4666ESE+ integrates two NC and two NO switches with guaranteed break-before-make timing. All share identical RON, leakage, supply, and logic specs - only switch configuration and truth table differ.
Is the MAX4665ESE+ pin-compatible with other SOIC-16 analog switches like the DG418?
No - while both are SOIC-16 quad SPST switches, the MAX4665ESE+ uses nonstandard pinout: IN1–IN4 occupy pins 1/8/9/16, COM1–COM4 are on 2/7/10/15, and NO1–NO4 are on 3/6/11/14. The DG418 places all INs on one side and COM/NO on the other, making direct PCB replacement impossible without layout revision.
