Product details
Overview
MAX4601EWE from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max RON match between channels, and 2.5nA max off-leakage at +85°C, enabling low-distortion audio-signal routing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4601EWE datasheet, MAX4601EWE pinout, MAX4601EWE application, or MAX4601EWE equivalent, key selection criteria include its -40°C to +85°C industrial temperature range, 16-pin Wide SO package, dual-supply (±4.5V to ±20V) or single-supply (+4.5V to +36V) operation, and TTL/CMOS-compatible logic thresholds.
Technical Context
The MAX4601EWE implements CMOS transmission-gate architecture with integrated level-shifting circuitry to support TTL/CMOS logic inputs across ±15V or +12V supply configurations. Its internal protection diodes clamp signals exceeding V+ or V−, and all four NC switches share matched on-resistance profiles over ±10V signal ranges.
It features guaranteed RON flatness of 0.5Ω max across the full analog input range and supports high-frequency operation up to 100MHz in 50Ω systems, with off-isolation >56dB at DC–1MHz and charge injection of only 20pC typical-critical for sample-and-hold and multiplexer applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| RON Match Between Channels | 0.5Ω max - enables precise channel-to-channel gain matching in instrumentation and mux applications |
| Off-Leakage Current | 2.5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and integrator circuits |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and telecom power architectures |
| Logic Thresholds | VIN_H = 2.4V, VIN_L = 0.8V - guarantees direct interfacing with standard TTL/CMOS controllers without level shifters |
| Turn-On/Off Time | 160ns / 170ns typical - enables fast switching in automated test and communication system timing paths |
| Charge Injection | 20pC typical - minimizes settling error in sampling circuits and data acquisition front-ends |
Pinout & Package
MAX4601EWE is housed in a 16-pin Wide SO (SOIC-W) package with 0.3-inch body width and standard 1.27mm pitch. The package is RoHS-compliant, surface-mountable, and rated for industrial temperature operation (-40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs for respective NC switches; active-low logic sense (logic 0 = ON) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to NC outputs when switch is enabled |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog outputs - conduct to COM when IN = 0; open when IN = 1 |
| 4 | V− | Negative analog supply rail - tied to GND for single-supply use |
| 5 | GND | Digital and substrate ground reference |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V for independent logic-level control |
| 13 | V+ | Positive analog supply rail - defines upper signal swing limit |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for full-scale audio and sensor signal routing |
| Guaranteed RON Flatness | 0.5Ω max variation over ±10V signal range - maintains consistent gain and linearity across input amplitude |
| ESD Protection | >2000V per Method 3015.7 - enhances robustness in handling-sensitive production and field environments |
| Low Power Consumption | I+ and I− < 0.5µA typical - reduces thermal load and simplifies power budgeting in dense PCB layouts |
| High Off-Isolation | 56dB min at 1MHz - suppresses crosstalk between inactive channels in multi-path routing |
Applications
| Reed Relay Replacement | Test Equipment Signal Routing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Quad SPST, NO configuration; 1.8Ω max RON; requires ≥4.5V logic supply; no VL pin | Requires redesign of control logic polarity and power domain; better RON but lacks NC default state | Select when lower on-resistance is prioritized and NC fail-safe behavior is not required |
| TS5A23157DCUR | Quad SPST, NO/NC configurable per channel; 0.9Ω max RON; single 1.65V–5.5V supply only; no dual-supply support | Not suitable for ±15V avionics or high-voltage test systems; limited to low-voltage portable audio | Choose for battery-powered consumer audio where supply headroom is constrained and NC default is optional |
Compared with MAX4601EWE, ADG1411BRUZ offers lower RON but removes NC safety default and VL flexibility, while TS5A23157DCUR sacrifices high-voltage compatibility for ultra-low RON and smaller footprint-making MAX4601EWE uniquely suited for industrial and aerospace NC-critical designs.

FAQ
What is the logic polarity of the MAX4601EWE control inputs?
The MAX4601EWE uses active-low logic: a logic 0 (≤0.8V) on IN1–IN4 turns the corresponding NC switch ON (COM connected to NC), while a logic 1 (≥2.4V) turns it OFF. This default-closed behavior provides fail-safe signal continuity during power loss or controller reset-critical in safety-aware systems using MAX4601EWE.
Can the MAX4601EWE operate from a single 5V supply?
No. The MAX4601EWE requires minimum ±4.5V dual supply or +4.5V to +36V single supply. At 5V single supply, V− must be connected to GND and V+ to +5V, satisfying the +4.5V minimum. Operation below 4.5V violates absolute maximum ratings and risks undefined switching behavior in MAX4601EWE.
Does the MAX4601EWE support rail-to-rail analog signals with a single +12V supply?
Yes. With V+ = +12V and V− = GND, the MAX4601EWE passes analog signals from 0V to +12V without clipping. Its CMOS transmission-gate design and internal level-shifting allow full rail-to-rail conduction-verified in electrical characteristics tables for single +12V operation in the MAX4601EWE datasheet.
What is the purpose of the VL pin on the MAX4601EWE?
The VL pin on MAX4601EWE sets the logic threshold reference independently from analog supplies. It accepts 2.7V to 5.5V and defines the 0.8V/2.4V input thresholds, enabling reliable TTL/CMOS interfacing even when V+ is ±15V or +36V-eliminating need for external level shifters in mixed-voltage systems using MAX4601EWE.
How does the MAX4601EWE handle overvoltage conditions on analog pins?
The MAX4601EWE includes internal ESD diodes from COM/NC/NO pins to V+ and V−. If analog signals exceed V+ or fall below V−, current flows through these diodes. To prevent damage, external series diodes (as shown in Figure 1 of the MAX4601EWE datasheet) are recommended when supply sequencing cannot guarantee V+ powers first-protecting MAX4601EWE without degrading RON.
