Product details
Overview
MAX4664ESE from Maxim Integrated is a quad, single-pole single-throw (SPST), normally closed (NC) analog switch IC with 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 guaranteed 0.5Ω max on-resistance matching and flatness, 5nA max off-leakage at +85°C, and TTL/CMOS-compatible logic inputs - ideal for reed relay replacement in automatic test equipment and audio-signal routing.
For engineers reviewing the MAX4664ESE datasheet, MAX4664ESE pinout, MAX4664ESE application, or MAX4664ESE equivalent, key selection criteria include NC-switch topology, -40°C to +85°C industrial temperature rating, 16-pin narrow SO package, break-before-make absence (distinguishing it from MAX4666), and verified performance under ±15V dual supply with 100mA continuous channel current capability.
Technical Context
The MAX4664ESE implements four independent CMOS SPST switches with normally closed configuration - each COM terminal connects to its corresponding NC terminal when the control input is logic low. Its architecture uses matched P- and N-channel MOSFETs to achieve low, flat on-resistance across the full ±10V analog signal range without distortion.
All four channels share common analog supply pins (V+, V−), logic supply (VL), and ground (GND), with individual digital inputs (IN1–IN4) controlling switch state. The device guarantees no overlap between ON and OFF states (no break-before-make), distinguishing it functionally from the MAX4666 variant and enabling deterministic NC behavior in safety-critical signal gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to 100mA. |
| RON Matching | 0.5Ω max between channels - enables precise gain/phase tracking in multi-channel instrumentation. |
| RON Flatness | 0.5Ω max over ±10V signal range - preserves linearity in audio and sensor signal conditioning. |
| Off-Leakage Current | 5nA max at +85°C - prevents DC error accumulation in high-impedance measurement circuits. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and telecom voltage rails. |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility with +12V or ±15V supplies. |
| Turn-On/Off Time | 225ns / 100ns typical (single supply, V+ = +12V) - suitable for multiplexing up to ~1MHz signals. |
Pinout & Package
MAX4664ESE is housed in a 16-pin narrow SOIC (SOICN) package, 3.9mm width, 1.75mm height, 1.27mm pitch, RoHS-compliant and moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs: logic low closes NC path; logic high opens switch (normally closed topology). |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load; current path shared with NC pins. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when INx = low; open when INx = high. |
| 4 | V− | Negative analog supply - tie to GND for single-supply operation; supports ±20V dual-rail operation. |
| 5 | GND | Digital/analog reference ground - must be low-impedance connection to minimize noise coupling. |
| 12 | VL | Logic supply input - accepts +2.7V to +5.5V; decoupling capacitor required for stable switching. |
| 13 | V+ | Positive analog supply - supports up to +36V; defines upper rail for rail-to-rail analog signal range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±10V differential signals with <0.5Ω RON variation - eliminates clipping in precision op-amp interfaces. |
| Guaranteed RON match & flatness | 0.5Ω max channel-to-channel mismatch and flatness - enables simultaneous sampling in data acquisition systems. |
| TTL/CMOS-compatible logic inputs | +0.8V/+2.4V thresholds with <0.5µA input current - allows direct interfacing to microcontrollers without level shifters. |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling and board assembly environments. |
| Low off-leakage at elevated temperature | 5nA max at +85°C - maintains accuracy in thermally demanding test equipment and avionics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4665ESE | Quad SPST, normally open (NO) topology - opposite logic sense and default-open behavior. | Suitable where fail-open safety is required (e.g., emergency shutdown paths), not fail-closed. | Select MAX4665ESE only when NC default is unsafe; identical package, supply, and RON specs otherwise. |
| ADG1414BRUZ | Quad SPST, NO/NC configurable via internal register; 4.5Ω max RON but requires SPI interface and 3.3V logic supply. | Used in programmable signal routers where dynamic topology reconfiguration is needed. | Choose ADG1414BRUZ only if SPI control and software-defined switching states are required; not pin-compatible. |
Compared with MAX4664ESE, MAX4665ESE offers identical electrical specs but inverted default state - critical for safety logic - while ADG1414BRUZ adds configurability at the cost of interface complexity and non-drop-in replacement.

FAQ
What is the default switch state of MAX4664ESE when power is applied?
The MAX4664ESE features a normally closed (NC) topology: all four switches are closed (COM connected to NC) when IN1–IN4 are logic low or un-driven. With no logic input applied, internal weak pull-downs ensure default closure - a key safety feature for fail-closed system architectures. This behavior is confirmed in the truth table and pin description sections of the MAX4664ESE datasheet.
Can MAX4664ESE operate from a single +5V supply?
No - the MAX4664ESE requires a minimum analog supply of +4.5V for single-supply operation, and its specified performance (including 5Ω max RON and rail-to-rail signal handling) is validated down to +4.5V, not +5V. At +5V, it functions but RON increases and flatness degrades; for robust +5V-system use, consider the MAX4664CSE (0°C to +70°C) or verify operation per Electrical Characteristics Table for single-supply conditions.
Does MAX4664ESE support break-before-make switching?
No - the MAX4664ESE does not guarantee break-before-make timing. That feature is exclusive to the MAX4666 variant (two NC + two NO channels). The MAX4664ESE's four NC switches transition directly between closed and open states without intentional overlap or gap; designers requiring BMB must select MAX4666ESE or add external timing control.
What is the maximum analog signal voltage the MAX4664ESE can handle?
The MAX4664ESE supports rail-to-rail analog signals from V− to V+, with guaranteed performance up to ±10V differential across COM–NC terminals when operated within its absolute maximum ratings (V+ to V− ≤ 44V). For example, with V+ = +15V and V− = −15V, the device passes signals from −15V to +15V - but RON flatness and leakage are specified over ±10V, not full rail.
Is MAX4664ESE pin-compatible with other variants in the MAX4664/MAX4665/MAX4666 family?
Yes - MAX4664ESE, MAX4665ESE, and MAX4666ESE share identical 16-pin narrow SOIC footprints and pinouts, including V+, V−, GND, VL, IN1–IN4, COM1–COM4, and NC1–NC4/NO1–NO4 assignments. However, internal switch topology differs: MAX4664ESE is NC-only, MAX4665ESE is NO-only, and MAX4666ESE mixes both. Swapping requires logic inversion and functional validation.
