Product details
Overview
MAX4674ETE+ from Maxim Integrated is a low-voltage, quad 2:1 analog multiplexer/demultiplexer IC operating from a single +1.8V to +5.5V supply. It delivers 4Ω max on-resistance at +5V, 0.4Ω max RON matching between channels, and 18ns max turn-on time - enabling high-fidelity audio/video signal routing and low-leakage data-acquisition switching in space-constrained industrial and communications systems.
For engineers reviewing the MAX4674ETE+ datasheet, MAX4674ETE+ pinout, MAX4674ETE+ application, or MAX4674ETE+ equivalent, key selection criteria include guaranteed rail-to-rail signal handling, -114dB crosstalk at 1MHz, break-before-make timing (1ns max), and QFN-16 package compatibility with high-density PCB layouts.
Technical Context
The MAX4674ETE+ implements four independent CMOS transmission-gate-based 2:1 switches, each with dedicated COM, NO, and NC terminals controlled by A0 address and EN active-low enable. Its internal logic ensures strict break-before-make operation to prevent signal shorting during channel transitions.
All digital inputs (A0, EN) feature TTL/CMOS-compatible thresholds scalable with V+: +2.4V/+0.8V at +5V supply, +2.0V/+0.4V at +3V supply. Analog signal range spans rail-to-rail (0V to V+), supported by internal ESD diodes clamping NO/NC/COM pins to V+ and GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +5V supply - enables ≤100mA continuous current per channel without significant voltage drop or self-heating. |
| RON Matching | 0.4Ω max between channels - ensures consistent gain/attenuation across all four multiplexers in precision signal-path applications. |
| Turn-On/Off Time | 18ns / 6ns max - supports high-speed signal switching up to ~50MHz bandwidth in 50Ω systems. |
| Off-Leakage Current | 0.5nA max at +25°C - critical for maintaining accuracy in high-impedance sensor interfaces and battery-powered data loggers. |
| Crosstalk | -114dB at 1MHz - suppresses interference between adjacent switched channels in multi-source audio/video routing. |
| Supply Range | +1.8V to +5.5V single supply - allows direct integration with 1.8V, 3.3V, and 5V logic domains without level shifters. |
| Off-Isolation | -67dB at 1MHz - blocks unwanted signal coupling from disabled channels into active signal paths. |
Pinout & Package
MAX4674ETE+ is supplied in a 4mm × 4mm, 16-pin QFN package with exposed pad (EP), optimized for thermal performance and high-density layout. Pin 1 is marked via top-side dot; EP must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Address Input | Selects NO1/NC1 or NO2/NC2 pair per switch; logic level determines which input connects to COMx. |
| EN | Enable (Active Low) | Global control: pulls all four switches open when high; enables switching when low. |
| COM1–COM4 | Analog Common Terminals | Output nodes shared across both NOx and NCx paths; connect to downstream signal chain (e.g., ADC input, amplifier). |
| NO1–NO4 | Normally Open Terminals | Signal inputs routed to COMx only when A0 = 1 and EN = low - default open state prevents unintended connection. |
| NC1–NC4 | Normally Closed Terminals | Signal inputs routed to COMx only when A0 = 0 and EN = low - default closed path maintains continuity during power-up. |
| V+ | Positive Supply | Single supply rail powering internal CMOS switches and logic; sets analog signal ceiling (0V to V+). |
| GND | Ground Reference | Return path for supply current and analog signal reference; EP must be connected here for thermal and EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without clipping - essential for full-scale audio, sensor, and DAC output routing. |
| Guaranteed break-before-make | 1ns max transition interval prevents momentary shorting between NOx and NCx during A0 toggling - eliminates signal glitches. |
| TTL/CMOS logic compatibility | Input thresholds scale with V+ (e.g., VIH = 2.4V at +5V, 2.0V at +3V) - enables direct interfacing with mixed-voltage microcontrollers. |
| Low charge injection (10pC typ) | Minimizes voltage transient on COMx during switching - preserves integrity of sampled signals in data-acquisition front-ends. |
| High off-isolation (-67dB @1MHz) | Effectively isolates inactive channels from sensitive measurement nodes - reduces crosstalk in multi-channel instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher RON (9.5Ω typ at +5V), wider supply (±5V dual or +5V single), 16-TSSOP only | Better suited for bipolar signal routing; less optimal for ultra-low-RON unipolar systems | Choose ADG1414BRUZ if ±5V operation or higher breakdown voltage (>20V) is required. |
| TS3A4751PWR | Lower RON (0.5Ω typ at +3.3V), no NC terminals, 16-TSSOP, lower isolation (-60dB) | Optimized for mobile audio; lacks NC path and high-frequency isolation needed in test equipment | Choose TS3A4751PWR only for cost-sensitive, low-voltage, NO-only routing where NC functionality is unnecessary. |
Compared with ADG1414BRUZ and TS3A4751PWR, MAX4674ETE+ uniquely combines NC/NO dual-path architecture, 4Ω max RON, -114dB crosstalk, and QFN-16 thermal performance - making it the preferred choice for high-fidelity, high-reliability industrial multiplexing where signal path integrity and layout density are critical.

FAQ
What is the maximum analog signal voltage range supported by the MAX4674ETE+?
The MAX4674ETE+ supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. When powered from +5V, the signal range is 0V to +5V. Internal ESD diodes clamp NO/NC/COM pins to V+ and GND, so signals exceeding these limits require external protection. This range enables direct interface with most ADCs, DACs, and op-amps without level-shifting circuitry.
Does the MAX4674ETE+ support break-before-make switching, and is it guaranteed?
Yes, the MAX4674ETE+ guarantees break-before-make operation with a maximum interval of 1ns across temperature and supply voltage. This is confirmed in the Electrical Characteristics table under "Break-Before-Make (tBBM)" and ensures no momentary shorting between NOx and NCx terminals during A0 transitions - critical for preventing signal corruption in sensitive analog paths.
Can the MAX4674ETE+ be used with a +3.3V supply, and how does performance change?
Yes, the MAX4674ETE+ operates fully across +1.8V to +5.5V, including +3.3V. At +3V supply, RON increases to 6Ω max (vs. 4Ω at +5V), tON/tOFF increase to 25ns/10ns max, and logic thresholds adjust to VIH = 2.0V/VIL = 0.4V - maintaining full TTL/CMOS compatibility. These values are specified and tested per the +3V Electrical Characteristics table.
What is the function of the NC (Normally Closed) terminals in the MAX4674ETE+?
The NC terminals (NC1–NC4) provide a default-closed signal path when A0 = 0 and EN = low. This enables fail-safe or default-routing behavior - for example, connecting a backup sensor or maintaining system continuity during microcontroller boot-up before A0 is configured. The NC/NO dual-path architecture distinguishes MAX4674ETE+ from simpler SPDT switches lacking this redundancy capability.
Is the exposed pad (EP) on the MAX4674ETE+ QFN package required to be connected to ground?
Yes, the exposed pad (EP) on the MAX4674ETE+ QFN package must be soldered to a PCB ground plane. It serves as the primary thermal dissipation path and improves EMI performance. The datasheet specifies EP as "Exposed Pad. Connect to GND." Omitting this connection risks thermal overload under sustained 100mA channel current and degrades high-frequency isolation and crosstalk performance.
