Product details
Overview
MAX4741EUA+ from Maxim Integrated is a dual SPST analog switch with two normally open (NO) channels, designed for low-voltage signal routing in battery-powered and portable systems. It features 0.8Ω max on-resistance at +3V supply, 24ns turn-on time, rail-to-rail analog signal handling (0V to V+), and consumes <1µW quiescent power - enabling high-fidelity audio switching and precision data-acquisition paths.
For engineers reviewing the MAX4741EUA+ datasheet, MAX4741EUA+ pinout, MAX4741EUA+ application, or MAX4741EUA+ equivalent, key selection criteria include on-resistance matching (0.08Ω max), break-before-make absence (distinguishing it from MAX4743), 1.8V CMOS logic compatibility, and µMAX package thermal performance (362mW at +70°C).
Technical Context
The MAX4741EUA+ uses CMOS switch architecture to support bidirectional, rail-to-rail analog signals from GND to V+ across both channels. Its control logic accepts 1.8V-compatible inputs even when V+ = +1.8V, with VIH = 1.0V and VIL = 0.4V - enabling direct interfacing with low-voltage microcontrollers without level shifting.
Each channel operates independently with no break-before-make timing; switching is simultaneous and monotonic. On-resistance flatness is specified at 0.18Ω max over the full analog range at +3V, ensuring minimal THD (0.02% typical) and consistent gain accuracy in audio and sensor signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.8Ω max at V+ = +3V, 100mA load - enables ≤50mV drop at 62.5mA, suitable for precision current-sense and low-distortion audio routing. |
| RON Matching | 0.08Ω max between channels - ensures matched gain/attenuation in differential or dual-path signal conditioning. |
| Turn-On/Off Time | tON = 24ns max, tOFF = 16ns max (RL = 50Ω, CL = 35pF) - supports >10MHz digital signal switching and fast multiplexing in data acquisition. |
| Analog Signal Range | 0V to V+ (rail-to-rail) - preserves full dynamic range of baseband audio, sensor outputs, and ADC/DAC interfaces. |
| Supply Voltage Range | +1.6V to +3.6V single supply - compatible with Li-ion (3.0–3.6V), Li-poly (2.7–3.3V), and coin-cell (1.8V) power sources. |
| Logic Compatibility | 1.8V CMOS input thresholds at +3V supply (VIH = 1.4V, VIL = 0.5V) - interoperable with 1.8V/3.3V I/O domains without external translators. |
| Leakage Current | ±10nA max COM_ on-leakage at +85°C - maintains signal integrity in high-impedance sensor front-ends and battery-monitoring circuits. |
Pinout & Package
The MAX4741EUA+ is housed in an 8-pin µMAX® package (U8-1), measuring 3.05mm × 3.05mm × 1.05mm, with exposed pad for thermal enhancement and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1 / NO2 | Normally open analog terminals - connect only when corresponding IN1/IN2 is high; isolated otherwise (leakage <5nA). |
| 2, 7 | COM1 / COM2 | Common analog ports - serve as bidirectional signal path endpoints; support ±150mA continuous current per channel. |
| 3, 6 | IN2 / IN1 | Digital control inputs - TTL/CMOS compatible; drive switches directly from MCU GPIOs without pull-ups or level shifters. |
| 4, 5 | GND | Ground reference - must be low-impedance; bypass V+ to GND with 0.1µF capacitor near pins 7/8 for noise immunity. |
| 7, 2 | V+ | Positive supply - powers analog and logic sections; absolute max 4V; internal ESD protection clamps signals beyond V+ or GND. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 0.18Ω max variation across 0V–V+ range at +3V - minimizes harmonic distortion (<0.02%) in audio and instrumentation signals. |
| Rail-to-rail signal handling | Full GND-to-V+ analog swing supported - eliminates clipping in battery-powered audio codecs and sensor amplifiers. |
| Ultra-low quiescent power | <1µW supply current at +3.6V - extends runtime in always-on wearable and IoT edge nodes. |
| High-current capability | 150mA continuous per channel - sufficient for driving LED bias, relay coils, or multi-channel ADC front-ends. |
| Low charge injection | 28pC typical - reduces glitch-induced offset in precision sample-and-hold and multiplexed sensor systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4742EUA+ | Two normally closed (NC) switches instead of NO; identical RON, timing, and package. | Used where default-closed signal paths are required (e.g., fail-safe sensor monitoring). | Select MAX4742EUA+ only when NC behavior is mandatory; not interchangeable without circuit redesign. |
| TMUX1574DBVR | 0.5Ω max RON at 3.3V, but requires ≥1.08V logic high; no 1.8V CMOS compatibility at 1.8V supply. | Better RON for high-speed data muxing, but incompatible with 1.8V logic without level translation. | Choose TMUX1574DBVR only if lower RON justifies added logic interface complexity and higher supply voltage margin. |
Compared with MAX4742EUA+, the MAX4741EUA+ provides default-open isolation critical for power-gating; versus TMUX1574DBVR, it delivers guaranteed 1.8V logic compatibility and lower system-level BOM cost in battery-constrained designs.

FAQ
What is the maximum continuous current rating per channel for the MAX4741EUA+?
The MAX4741EUA+ supports ±150mA continuous current through each COM/NO channel. This rating holds across the full -40°C to +85°C operating range and enables direct switching of sensor bias currents, LED drivers, and ADC input buffers without external buffering. Exceeding this limit risks thermal overstress and parametric shift in on-resistance.
Does the MAX4741EUA+ support break-before-make switching?
No, the MAX4741EUA+ does not implement break-before-make switching. It is a dual normally open (NO) device with simultaneous channel control - meaning both switches transition concurrently. Break-before-make is exclusive to the MAX4743 variant; using MAX4741EUA+ in place of MAX4743EUA+ may cause momentary short-circuits in shared-bus configurations.
Can the MAX4741EUA+ operate from a 1.8V supply while accepting 3.3V logic inputs?
Yes, the MAX4741EUA+ logic inputs tolerate voltages up to +3.6V regardless of V+ supply level. When powered from +1.8V, IN1 and IN2 accept 0V/3.3V logic swings - eliminating need for level shifters when interfacing with 3.3V microcontrollers in mixed-voltage systems.
What is the thermal performance of the MAX4741EUA+ in its µMAX package?
The MAX4741EUA+ in the 8-pin µMAX package has a power dissipation limit of 362mW at +70°C, derating at 4.5mW/°C above that temperature. Its exposed pad enhances thermal conduction; PCB layout with ≥2cm² copper pour under the package reduces junction-to-ambient θJA to ~90°C/W, supporting reliable operation at full current in compact handheld devices.
How does the on-resistance of the MAX4741EUA+ vary with supply voltage and temperature?
At +3.0V supply, MAX4741EUA+ RON is 0.8Ω max at +25°C and rises to 0.9Ω max across -40°C to +85°C. At +1.8V, RON increases to 2.5Ω max due to reduced channel drive strength. The variation remains monotonic and predictable - confirmed by Figure toc01 and toc02 in the datasheet - enabling accurate gain calibration in production firmware.
