Product details
Overview
MAX4665EPE from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 5Ω max on-resistance, 0.5Ω max on-resistance match between channels, and 5nA max off-leakage current at +85°C - enabling low-distortion audio-signal routing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4665EPE datasheet, MAX4665EPE pinout, MAX4665EPE application, or MAX4665EPE equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max over ±10V signal range), TTL/CMOS-compatible logic thresholds (+0.8V / +2.4V), and dual-supply operation (±4.5V to ±20V) or single-supply operation (+4.5V to +36V).
Technical Context
The MAX4665EPE implements CMOS-based SPST switching architecture with break-before-make timing not guaranteed (unlike MAX4666), and features integrated ESD protection (>2kV per Method 3015.7). Its analog signal path supports full rail-to-rail operation across V− to V+, with matched channel performance validated over −40°C to +85°C.
All four switches share independent digital control inputs (IN1–IN4) referenced to VL, while analog terminals (COM1–COM4, NO1–NO4) operate from separate ±15V or +12V supplies. Logic inputs maintain consistent +0.8V low / +2.4V high thresholds regardless of supply configuration, ensuring interoperability with standard TTL/CMOS drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match Between Channels | 0.5Ω max - enables accurate gain matching in multi-channel instrumentation |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent insertion loss across full signal swing |
| Off-Leakage Current | 5nA max at +85°C - preserves DC accuracy in high-impedance sensor interfaces |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial and avionics power architectures |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees reliable switching with 3.3V/5V microcontrollers without level shifters |
| Turn-On/Off Time | 225ns / 100ns typical (single supply, V+ = +12V) - suitable for <1MHz multiplexing in data acquisition |
Pinout & Package
MAX4665EPE is housed in a 16-pin plastic DIP package (0.300" wide), with through-hole mounting and industry-standard pin spacing. Pin functions are electrically isolated between logic (VL, IN1–IN4) and analog (V+, V−, COM1–COM4, NO1–NO4) domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-high logic turns corresponding NO switch ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST topology |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - conduct only when respective INx = logic high |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation |
| 5 | GND | Digital ground reference - separate from analog supply return paths |
| 12 | VL | Logic supply input - accepts +3V to +5.5V, independent of analog supply rails |
| 13 | V+ | Positive analog supply - defines upper rail for rail-to-rail analog signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous signals from V− to V+ without clipping - critical for audio and sensor front-ends |
| Guaranteed RON flatness (0.5Ω max) | Minimizes harmonic distortion in AC-coupled applications like PBX line switching |
| TTL/CMOS-compatible logic inputs | Eliminates need for external level-shifting circuitry when interfacing with FPGA or MCU GPIO |
| ESD protection >2kV (HBM) | Enables robust handling during board assembly and field maintenance without additional protection devices |
| Low charge injection (25pC typical) | Reduces glitch-induced errors in sample-and-hold circuits and precision ADC front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4665ESE | Same electrical specs, but in 16-pin narrow SOIC package - 50% smaller footprint, surface-mount only | Preferred for space-constrained PCBs where reflow soldering is available | Select MAX4665ESE when board area is limited and thermal management allows SOIC packaging |
| ADG1414BRUZ | 4-channel SPST, 1.8Ω max RON, but requires minimum ±5V dual supply - no single-supply operation | Better RON for ultra-low-loss paths, but incompatible with +12V-only systems | Choose ADG1414BRUZ only if supply architecture supports dual rails and sub-2Ω RON is mandatory |
Compared with MAX4665ESE and ADG1414BRUZ, the MAX4665EPE uniquely combines through-hole reliability, single/dual-supply flexibility, and guaranteed RON flatness - making it optimal for industrial test fixtures and legacy avionics upgrades where layout change is constrained.

FAQ
What is the maximum supply voltage rating for MAX4665EPE?
The MAX4665EPE supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, use within specified ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these limits risks permanent damage due to internal diode clamping.
Does MAX4665EPE support rail-to-rail analog signal switching?
Yes, the MAX4665EPE supports true rail-to-rail analog signal handling - signals from V− to V+ pass unclamped through the switch. This is confirmed in both dual-supply (±15V) and single-supply (+12V, V− = GND) configurations, enabling full utilization of ADC/DAC dynamic range in precision systems.
What is the guaranteed on-resistance match between channels for MAX4665EPE?
The MAX4665EPE guarantees ≤0.5Ω maximum on-resistance mismatch (∆RON) between any two channels under all operating conditions (−40°C to +85°C, full supply and signal range). This specification is 100% tested and ensures predictable gain tracking in multi-channel instrumentation.
Can MAX4665EPE be used with a single +5V supply?
No - the MAX4665EPE requires minimum +4.5V for single-supply operation, but its analog signal range is defined relative to V+ and V−. With V− = GND, the device operates correctly at +5V, though RON increases slightly versus +12V or +15V. Logic inputs remain compatible via VL = +5V.
Is break-before-make timing guaranteed for MAX4665EPE?
No - break-before-make timing is explicitly guaranteed only for the MAX4666 variant (two NO + two NC switches). The MAX4665EPE is a four-channel normally open device with no guaranteed break-before-make behavior; overlapping conduction may occur during logic transitions.
