Product details
Overview
MAX4674EUE+ 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 routing and low-distortion data-acquisition signal paths in space-constrained industrial and communications systems.
For engineers reviewing the MAX4674EUE+ datasheet, MAX4674EUE+ pinout, MAX4674EUE+ application, or MAX4674EUE+ equivalent, key selection criteria include guaranteed RON flatness (±0.8Ω), rail-to-rail analog signal handling, -114dB crosstalk at 1MHz, and TTL/CMOS-compatible digital inputs with independent 5.5V-tolerant A0/EN control under 3.3V V+ operation.
Technical Context
The MAX4674EUE+ implements four independent bidirectional analog switches, each with break-before-make switching (1ns max tBBM) and guaranteed monotonic RON over full signal range (0V to V+). Its CMOS architecture uses matched transistor pairs per channel to achieve 0.4Ω max RON mismatch and <±0.5nA leakage at +25°C.
Digital control employs two logic inputs: active-low EN enables all four switches simultaneously, while A0 selects between NC and NO paths per channel. Input thresholds scale with V+ (VIH = 2.4V at +5V; 2.0V at +3V), supporting mixed-voltage system interfacing without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +5V supply - ensures minimal voltage drop and power loss when switching ±100mA continuous analog signals. |
| RON Matching | 0.4Ω max between channels - critical for precision instrumentation where gain/offset tracking across multiple signal paths must be preserved. |
| Turn-On Time (tON) | 18ns max - supports high-speed multiplexing in >50MHz bandwidth applications such as video line switching and fast ADC sampling. |
| Crosstalk | -114dB at 1MHz - prevents interference between adjacent switched channels in multi-source audio or sensor aggregation systems. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full utilization of supply headroom for unipolar/bipolar signal routing without clipping. |
| Off-Isolation | -67dB at 1MHz - maintains signal integrity by suppressing coupling from disabled channels into active signal paths. |
| Supply Voltage Range | +1.8V to +5.5V - enables direct integration into battery-powered, 3.3V, and legacy 5V systems without external regulators. |
Pinout & Package
MAX4674EUE+ 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; pin 8 is GND; pin 16 is V+; pin 15 is EN (active-low enable).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 (Pin 1) | Channel address input | Selects normally open (NO) or normally closed (NC) path per switch; compatible with 3.3V/5V logic regardless of V+ level. |
| EN (Pin 15) | Global enable input | Active-low control disables all four switches simultaneously; 5.5V-tolerant for use with higher-voltage controllers. |
| V+ (Pin 16) | Positive supply | Powers internal CMOS switches and sets analog signal limits; supports 1.8–5.5V operation with scaled logic thresholds. |
| GND (Pin 8) | Ground reference | Return path for analog signals and digital logic; exposed pad must be soldered to PCB ground plane for thermal stability. |
| COM1–COM4 (Pins 4,7,9,12) | Common analog terminals | Bidirectional signal ports connecting to load/sensor; each supports rail-to-rail voltage swing and ±100mA continuous current. |
| NO1–NO4 (Pins 3,6,10,13) | Normally open switch outputs | Connect to COMx only when A0 = high; low capacitance (10pF off-state) minimizes high-frequency loading. |
| NC1–NC4 (Pins 2,5,11,14) | Normally closed switch outputs | Connect to COMx only when A0 = low; identical RON and leakage specs as NO terminals ensure path symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without distortion or clipping - essential for full-scale sensor output or audio waveform routing. |
| Guaranteed RON flatness | ±0.8Ω over entire signal range - eliminates gain nonlinearity in precision measurement front-ends and calibrated test equipment. |
| Break-before-make switching | 1ns max interval prevents momentary short-circuit between NC and NO paths - protects sensitive sources and avoids signal glitches. |
| TTL/CMOS logic compatibility | VIH = 2.4V / VIL = 0.8V at +5V V+; thresholds scale down to VIH = 2.0V at +3V - eliminates need for external level translators in mixed-voltage designs. |
| Low charge injection | 10pC typical - reduces voltage transient errors during switching in sample-and-hold circuits and high-impedance sensor interfaces. |
| High off-isolation | -67dB at 1MHz - isolates inactive signal sources to prevent crosstalk-induced noise in multi-channel audio mixers or RF front-ends. |

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), but larger 20-lead TSSOP package. | Better suited for dual-supply industrial systems requiring ±15V analog rails; less optimal for ultra-low-voltage (1.8V) portable designs. | Choose ADG1414BRUZ when bipolar supply operation or higher voltage tolerance is required; MAX4674EUE+ remains superior for single-supply, low-RON, and space-constrained layouts. |
| TS5A23157DCUR | Lower RON (0.9Ω typ at +3.3V), smaller 10-pin VSSOP package, but only dual-channel (not quad) and no break-before-make guarantee. | Ideal for cost-sensitive dual-path applications like USB signal switching; lacks channel count and timing assurance for synchronized 4-channel acquisition. | Choose TS5A23157DCUR for compact dual-switch needs with lowest possible RON; MAX4674EUE+ is preferred when four synchronized, break-before-make paths are mandatory. |
Compared with ADG1414BRUZ and TS5A23157DCUR, the MAX4674EUE+ uniquely balances quad-channel density, 4Ω max RON, guaranteed break-before-make, and 1.8V operation - making it optimal for space-limited, low-voltage, high-fidelity multiplexing where channel count and timing integrity are non-negotiable.

FAQ
What is the maximum supply voltage for MAX4674EUE+?
The MAX4674EUE+ has an absolute maximum supply voltage (V+) of +6V, but its specified operational range is +1.8V to +5.5V. Operating beyond +5.5V risks permanent damage per Absolute Maximum Ratings. For reliable long-term function, maintain V+ within 1.8V–5.5V, with +5V delivering optimal RON (4Ω max) and timing (18ns tON). The MAX4674EUE+ datasheet confirms this range across all temperature grades.
Does MAX4674EUE+ support break-before-make switching?
Yes, the MAX4674EUE+ guarantees break-before-make operation with a maximum interval of 1ns, as verified in the Electrical Characteristics table under "Break-Before-Make (tBBM)". This prevents momentary short-circuits between NC and NO paths during channel switching - a critical feature for protecting sensitive signal sources and avoiding transients in precision measurement systems using the MAX4674EUE+.
Can MAX4674EUE+ operate with a 3.3V supply?
Yes, the MAX4674EUE+ is fully specified for +3.3V operation (within its +2.7V to +3.3V range), delivering 6Ω max RON, 22ns max tON, and TTL/CMOS-compatible logic thresholds (VIH = 2.0V, VIL = 0.4V). Its ability to accept 5.5V-tolerant A0/EN inputs while running from 3.3V V+ simplifies interface with legacy 5V controllers - a key advantage confirmed in the MAX4674EUE+ General Description and Electrical Characteristics sections.
What is the thermal pad requirement for MAX4674EUE+?
The MAX4674EUE+ uses a standard 16-pin TSSOP package without an exposed thermal pad - unlike the QFN variants (e.g., MAX4674EGE+). Its thermal performance relies on standard PCB copper pour under pins and ambient convection. The MAX4674EUE+ datasheet specifies 533mW maximum power dissipation at +70°C with 6.7mW/°C derating above that temperature, confirming no internal thermal pad exists for this variant.
How does MAX4674EUE+ handle analog signals exceeding the supply rails?
The MAX4674EUE+ includes internal ESD-protection diodes between each analog pin (COM/NO/NC) and both V+ and GND. If an analog signal exceeds V+ or drops below GND, the corresponding diode conducts - limiting excursion to ~0.3V beyond rails. However, this condition increases leakage and may cause latch-up if current exceeds ±300mA peak (1ms, 10% duty cycle). The MAX4674EUE+ Absolute Maximum Ratings explicitly define these clamping limits.
