Product details
Overview
MAX4602CWE+ from Maxim Integrated is a quad single-pole single-throw (SPST) CMOS analog switch with four normally open (NO) configurations, rail-to-rail signal handling capability, 2.5Ω maximum on-resistance, 0.4Ω typical on-resistance flatness, and ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation. It serves as a low-distortion, solid-state replacement for electromechanical relays in automated test equipment signal routing.
For engineers reviewing the MAX4602CWE+ datasheet, MAX4602CWE+ pinout, MAX4602CWE+ application, or MAX4602CWE+ equivalent, key selection criteria include guaranteed RON matching (≤0.5Ω), sub-nA off-leakage at +85°C, TTL/CMOS-compatible logic thresholds, and 16-pin Wide SO package compatibility with high-density PCB layouts.
Technical Context
The MAX4602CWE+ implements fully independent SPST switches with separate COM–NO paths per channel, each controlled by a dedicated digital input (IN1–IN4). Its CMOS architecture ensures symmetrical conduction for AC/DC signals across the full supply range, with internal level-shifting enabling consistent switching behavior under ±15V or +12V supplies.
All four channels share a common V+, V−, VL, and GND, supporting simultaneous control while maintaining channel-to-channel RON match ≤0.5Ω and flatness ≤0.4Ω over −10V to +10V signal swing. Logic inputs tolerate 0.8V/2.4V thresholds regardless of analog supply configuration, eliminating external level translators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V |
| RON Match | 0.5Ω max - enables precise gain/phase matching in multi-channel instrumentation |
| RON Flatness | 0.4Ω max - maintains linear transfer function across full analog signal range (±10V) |
| Off-Leakage Current | 0.01nA typ at +25°C - preserves signal integrity in high-impedance sensor front-ends |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and avionics rails without external regulators |
| Logic Thresholds | 0.8V low / 2.4V high - guarantees direct interface with 5V TTL and CMOS controllers |
| Turn-On/Off Time | 160ns / 170ns typ - enables fast multiplexing in data acquisition systems up to ~3MHz |
Pinout & Package
MAX4602CWE+ is housed in a 16-pin Wide SO (SOIC-W) package with 0.3-inch body width and standard 1.27mm pitch. The package supports reflow soldering and meets JEDEC MS-013 specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic turns respective NO switch ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; connect to signal source or load return path |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs; conduct to COM only when corresponding IN = high |
| 4 | V− | Negative analog supply rail; tie to GND for single-supply operation |
| 5 | GND | Digital ground reference for logic inputs and VL |
| 12 | VL | Logic supply input; accepts 3V to 5V for level-shifted control interface |
| 13 | V+ | Positive analog supply rail; sets upper limit of rail-to-rail signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous DC and AC signals from V− to V+ without clipping or distortion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 4-channel, SPST, 1.8Ω RON, ±15V supply, but requires separate VDD/VSS pins (no VL pin) | Better RON but lacks dedicated logic supply; needs external level translation for 3.3V controllers | Select when lowest on-resistance is critical and board space allows discrete level-shifting |
| TS5A23157DGSR | 2-channel, SPDT, 0.9Ω RON, +1.65V to +5.5V single supply only, no dual-supply support | Lower voltage operation only; unsuitable for ±15V or +24V industrial signal chains | Select for battery-powered portable instruments where supply headroom is constrained to 3.3V/5V |
Compared with ADG1412BRUZ and TS5A23157DGSR, the MAX4602CWE+ uniquely combines quad NO topology, dual-supply flexibility, and a dedicated VL pin-making it optimal for mixed-signal systems requiring both high-voltage analog routing and low-voltage logic interfacing without added components.

FAQ
What is the operating temperature range for the MAX4602CWE+?
The MAX4602CWE+ is specified for commercial-grade operation from 0°C to +70°C. This temperature range is validated across all electrical parameters including RON, leakage, and switching times. For extended industrial use, the MAX4602EWE+ variant supports −40°C to +85°C and shares identical pinout and functionality with the MAX4602CWE+.
Can the MAX4602CWE+ operate from a single +12V supply?
Yes, the MAX4602CWE+ supports single-supply operation from +4.5V to +36V. When using +12V, connect V− to GND, apply +12V to V+, and supply 3V–5V to VL. All specifications-including 2.5Ω RON max and 0.01nA off-leakage-are guaranteed under this configuration per the datasheet's Single +12V Supply Electrical Characteristics table.
Does the MAX4602CWE+ require external protection diodes for overvoltage?
No, external protection diodes are not required for normal operation within absolute maximum ratings. The MAX4602CWE+ includes internal ESD diodes rated >2000V HBM. However, if supply sequencing cannot be guaranteed (e.g., V+ applied after V−), external series diodes may be added-but this reduces usable signal range by ~1.4V and is not recommended for single-supply use per Maxim's Application Information section.
How does the VL pin function in the MAX4602CWE+?
The VL pin on the MAX4602CWE+ provides an independent logic supply reference, decoupling digital input thresholds from analog supply rails. It accepts 3V to 5V and sets the 0.8V/2.4V logic thresholds regardless of whether V+ is +12V or ±15V. This allows direct interfacing with 3.3V microcontrollers even when routing ±10V analog signals-eliminating level-shifter ICs or resistive dividers.
Is the MAX4602CWE+ pin-compatible with other MAX460x variants?
Yes, all MAX460x variants-including MAX4601, MAX4602, and MAX4603-in 16-pin Wide SO packaging share identical pinouts and footprint. The only functional difference lies in switch configuration: MAX4601 is quad NC, MAX4602 is quad NO, and MAX4603 is dual NC/dual NO. Thus, MAX4602CWE+ can be substituted for MAX4601CWE+ or MAX4603CWE+ at the board level, provided logic polarity and signal routing are verified.
