Product details
Overview
MAX4602EWE from Maxim Integrated is a quad single-pole single-throw (SPST) normally open (NO) analog switch IC designed for precision signal routing in rail-to-rail analog paths. It delivers 2.5Ω maximum on-resistance, 0.4Ω typical on-resistance match between channels, and 0.4Ω typical on-resistance flatness over ±10V signal range. It operates from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies and supports TTL/CMOS-compatible control inputs - ideal for reed relay replacement in automated test equipment.
For engineers reviewing the MAX4602EWE datasheet, MAX4602EWE pinout, MAX4602EWE application, or MAX4602EWE equivalent, key selection criteria include guaranteed RON matching and flatness, low 2.5nA off-leakage at +85°C, rail-to-rail signal handling, and -40°C to +85°C industrial temperature rating with 16-pin Wide SO package.
Technical Context
The MAX4602EWE implements four independent CMOS SPST NO switches with matched channel characteristics and tightly controlled on-resistance variation across voltage and temperature. Its logic inputs feature fixed 0.8V/2.4V thresholds, enabling direct interface with TTL/CMOS systems without level-shifting when powered from ±15V or +12V supplies.
Each switch supports bidirectional rail-to-rail analog signals up to ±10V, with COM terminals rated for ±200mA continuous current and ±300mA pulsed current. The device integrates ESD protection >2000V per Method 3015.7 and uses internal clamping diodes to limit input overvoltage beyond V+ or V−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match | 0.5Ω max - guarantees consistent gain/attenuation across all four channels in multi-path routing |
| RON Flatness | 0.5Ω max over ±10V - maintains linear signal integrity across full analog input range |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sensor or sample-hold circuits |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial and test-system power architectures |
| Logic Thresholds | 0.8V low / 2.4V high - enables direct TTL/CMOS compatibility without external level shifters |
| Turn-On/Off Time | 160ns / 170ns typical - suitable for medium-speed multiplexing and switching applications up to ~1MHz |
Pinout & Package
MAX4602EWE is housed in a 16-pin Wide SO (SOIC-W) package with standard 0.3-inch body width and 0.050-inch lead pitch. Pin 1 is located at the top-left corner with notch or index mark identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs for respective NO switches; active-high logic turns switch ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path entry/exit points |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - connect to COM only when corresponding IN = high |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Digital/analog ground reference for logic and substrate bias |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V for independent logic-level control |
| 13 | V+ | Positive analog supply rail - sets upper analog signal limit and powers switch core |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ - eliminates clipping in ±15V or +12V systems |
| Guaranteed RON Matching | ≤0.5Ω max mismatch between any two channels - critical for balanced differential or multi-channel instrumentation |
| Low Charge Injection | 20pC typical - minimizes voltage glitch on sampled nodes in data acquisition systems |
| TTL/CMOS-Compatible Inputs | Fixed 0.8V/2.4V thresholds - removes need for external translators in mixed-voltage digital control |
| ESD Protection | >2000V HBM - enhances robustness during board handling and system integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST NO, 1.8Ω max RON, ±15V supply, but requires VL = V+ and lacks independent logic supply | Better RON but less flexible supply configuration; no separate VL pin limits mixed-voltage control | Select ADG1412BRUZ only if lower RON outweighs loss of independent logic-level control and wider temp range is not required |
| TS5A3157DCKR | Single SPST NO, 0.75Ω max RON, +1.65V to +5.5V supply only - no dual/rail-to-rail support | Not functionally equivalent: single-channel, limited voltage range, unsuitable for ±15V or high-voltage routing | TS5A3157DCKR serves low-voltage portable applications only; not a drop-in or functional alternative for MAX4602EWE's industrial use cases |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX4602EWE uniquely combines quad-channel NO topology, independent VL pin for flexible logic interfacing, rail-to-rail ±10V analog operation, and -40°C to +85°C qualification - making it irreplaceable in high-voltage, multi-channel, temperature-critical analog routing.

FAQ
What is the operating temperature range for the MAX4602EWE?
The MAX4602EWE is specified for operation from -40°C to +85°C, meeting industrial-grade environmental requirements. This rating applies across all electrical parameters including on-resistance, leakage current, and switching times, and is validated per the device's Absolute Maximum Ratings and Electrical Characteristics tables in the official datasheet.
Does the MAX4602EWE support rail-to-rail analog signal switching?
Yes, the MAX4602EWE supports true rail-to-rail analog signal handling - signals from V− to V+ are passed without clipping. This is confirmed by the "Input Voltage Range" specification (±10V with V+ = +15V, V− = −15V) and explicitly stated in the General Description as "each switch can handle Rail-to-Rail® analog signals."
What is the maximum allowable supply voltage for the MAX4602EWE?
The MAX4602EWE supports a single supply from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but functional operation is guaranteed only within the recommended supply ranges listed in the Electrical Characteristics table.
How does the VL pin function in the MAX4602EWE?
The VL pin on the MAX4602EWE provides an independent logic supply input, accepting 2.7V to 5.5V. It decouples logic-level thresholds from analog supply rails, enabling reliable TTL/CMOS-compatible switching even when V+ and V− operate at ±15V - a key differentiator from alternatives that tie logic supply to V+.
Is the MAX4602EWE pin-compatible with other devices in the MAX460x family?
Yes, the MAX4602EWE shares identical pinout and package (16-pin Wide SO) with MAX4601EWE and MAX4603EWE. However, internal switch configuration differs: MAX4601EWE is quad NC, MAX4602EWE is quad NO, and MAX4603EWE is dual NC/dual NO - requiring PCB-level logic inversion or routing changes for substitution.
