Product details
Overview
MAX4674EUE+T 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 signal routing in audio/video switching and low-voltage data-acquisition systems.
For engineers reviewing the MAX4674EUE+T datasheet, MAX4674EUE+T pinout, MAX4674EUE+T application, or MAX4674EUE+T equivalent, key selection criteria include guaranteed RON flatness (±0.8Ω), rail-to-rail signal handling, -114dB crosstalk at 1MHz, and TTL/CMOS-compatible digital inputs with independent 5.5V-tolerant A0/EN pins.
Technical Context
The MAX4674EUE+T implements four independent bidirectional 2:1 analog switches controlled by a single address input (A0) and active-low enable (EN). Each switch features break-before-make timing (1ns max) and internal ESD protection diodes on all analog terminals, allowing safe operation with signals extending beyond V+ or GND when current-limited.
Its CMOS architecture supports rail-to-rail analog signal ranges (0V to V+), operates with logic thresholds scaling with V+ (e.g., VIH = 2.0V at +3V supply), and maintains <1nA off-leakage at +25°C - critical for precision sensor multiplexing and battery-powered instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 4Ω max at +5V supply - ensures minimal voltage drop and power loss in signal paths up to ±100mA continuous current. |
| RON matching | 0.4Ω max between channels - enables precise gain-matching in multi-channel instrumentation and ADC front-ends. |
| Turn-on time (tON) | 18ns max - supports high-speed signal routing in 10/100Base-T Ethernet and video switching applications. |
| Crosstalk | -114dB at 1MHz - suppresses inter-channel interference in simultaneous multi-signal routing (e.g., stereo audio or dual ADC inputs). |
| Off-isolation | -67dB at 1MHz - prevents signal bleed-through from active to inactive channels in relay-replacement designs. |
| Analog signal range | 0V to V+ - allows full rail-to-rail signal handling without clipping, essential for wide-dynamic-range sensor interfaces. |
| Digital input tolerance | A0 and EN tolerate up to +5.5V regardless of V+ - permits direct interfacing with 5V logic while powered from +3.3V or +2.5V supplies. |
Pinout & Package
MAX4674EUE+T is housed in a 16-pin TSSOP package (4.4mm × 5.0mm body, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is A0 (address input); pins 2–4, 5–7, 9–11, and 12–14 form four COM/NO/NC switch groups; pin 8 is GND; pin 15 is EN (active-low enable); pin 16 is V+.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A0 | Address input selecting NO1/NC1 or NO2/NC2 per switch group - determines which analog path (normally open or normally closed) connects to COM. |
| 2,5,9,12 | NC1–NC4 | Normally closed terminals - conduct to respective COM pins when A0 = 0 and EN = low; used for default-path routing or fail-safe configurations. |
| 3,6,10,13 | NO1–NO4 | Normally open terminals - conduct to respective COM pins when A0 = 1 and EN = low; selected for active signal routing paths. |
| 4,7,11,14 | COM1–COM4 | Common analog terminals - bidirectional I/O nodes connecting to system signal sources or destinations (e.g., ADC input, codec line). |
| 8 | GND | Ground reference for internal logic and analog circuitry - must be low-impedance connection to minimize noise coupling and ensure leakage specification compliance. |
| 15 | EN | Active-low output enable - disables all switches (high-impedance state) when high; required for power sequencing and channel isolation during sleep modes. |
| 16 | V+ | Positive supply pin - powers internal CMOS switches and logic; sets analog signal ceiling (0V to V+) and defines logic threshold levels. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without distortion - eliminates level-shifting requirements in mixed-supply systems. |
| Guaranteed RON flatness | 0.8Ω max variation over full signal range - preserves amplitude accuracy across input voltage swing in precision measurement circuits. |
| TTL/CMOS logic compatibility | VIH = 2.4V / VIL = 0.8V at +5V supply - ensures reliable digital control from standard microcontroller GPIOs without external level translators. |
| Low charge injection | 10pC typical - minimizes voltage glitches at COM nodes during switching, critical for sample-and-hold and multiplexed ADC front-ends. |
| Break-before-make timing | 1ns max - prevents momentary short-circuit between NC and NO paths, protecting downstream circuitry in relay-replacement applications. |

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 (1.8Ω typ at +5V), wider supply range (+5V to ±15V), 16-TSSOP package. | Better suited for high-voltage industrial signal conditioning; less optimal for ultra-low RON requirement below 4Ω. | Select ADG1414BRUZ when bipolar supply operation or higher voltage tolerance is needed; MAX4674EUE+T preferred for low-RON, low-voltage systems. |
| TS5A23159DRCR | Lower RON (0.9Ω max at +3.3V), smaller 10-pin WSON package, no NC terminals - only NO/COM configuration. | Lacks normally-closed path option; optimized for space-constrained consumer electronics rather than relay-replacement use cases. | Choose TS5A23159DRCR for compact, cost-sensitive designs requiring only normally-open switching; retain MAX4674EUE+T when NC functionality or guaranteed RON matching is mandatory. |
Compared with ADG1414BRUZ and TS5A23159DRCR, the MAX4674EUE+T uniquely combines guaranteed 4Ω max RON, 0.4Ω max channel matching, and integrated NC/NO/COM topology - making it the only option among the three qualified for precision relay-replacement and multi-path instrumentation where path symmetry and fail-safe defaults are required.

FAQ
What is the maximum supply voltage rating for MAX4674EUE+T?
The absolute maximum supply voltage (V+) for MAX4674EUE+T is +6V. Operation above +5.5V risks permanent damage. The device is specified for reliable operation from +1.8V to +5.5V, with guaranteed performance including 4Ω max RON and 18ns tON within this range. Always observe proper power sequencing: apply V+ before logic inputs or analog signals.
Does MAX4674EUE+T support rail-to-rail analog signal operation?
Yes, MAX4674EUE+T supports true rail-to-rail analog signal handling from 0V to V+. This capability is enabled by its CMOS switch architecture and internal level-shifting circuitry, allowing undistorted passage of signals that swing fully between ground and the positive supply rail - essential for applications like sensor interfaces and audio routing where signal headroom is constrained.
Can MAX4674EUE+T be controlled directly by 5V logic while powered from a 3.3V supply?
Yes, MAX4674EUE+T allows 5V-tolerant digital control: A0 and EN inputs accept voltages up to +5.5V regardless of V+ supply level. When powered from +3.3V, these pins still meet VIH = 2.0V and VIL = 0.4V logic thresholds, enabling direct connection to 5V microcontrollers without level shifters - a key advantage confirmed in the device's Electrical Characteristics tables for +3V supply operation.
What is the significance of the "NC" pins on MAX4674EUE+T?
The NC (Normally Closed) pins on MAX4674EUE+T provide fail-safe or default signal paths: when A0 = 0 and EN = low, each NC pin conducts to its corresponding COM pin. This topology enables relay-replacement functionality - for example, maintaining a diagnostic loop or backup signal path during normal operation, then switching to NO paths only when actively commanded. NC pins are not no-connect; they are functional analog terminals.
How does MAX4674EUE+T achieve low crosstalk of -114dB at 1MHz?
MAX4674EUE+T achieves -114dB crosstalk at 1MHz through optimized on-chip layout, guard-ring isolation between adjacent switch channels, and low 10pF NO/NC off-capacitance. This performance is measured between any two channels under standard test conditions (CL = 5pF, RL = 100Ω) and ensures minimal interference in multi-channel audio, video, or sensor routing - a value verified in the device's Typical Operating Characteristics plots and Electrical Characteristics table.
