Product details
Overview
MAX4674ESE+T from Maxim Integrated is a low-voltage CMOS quad 2:1 analog multiplexer/demultiplexer 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 and data-acquisition systems.
For engineers reviewing the MAX4674ESE+T datasheet, MAX4674ESE+T pinout, MAX4674ESE+T application, or MAX4674ESE+T equivalent, key selection criteria include guaranteed RON flatness (±0.8Ω), rail-to-rail signal handling, -114dB crosstalk at 1MHz, and TTL/CMOS-compatible logic thresholds with +5V operation.
Technical Context
The MAX4674ESE+T implements four independent 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, supporting robust signal integrity in mixed-voltage systems.
Its digital interface accepts TTL/CMOS logic levels across its full supply range: VIH = 2.4V (min) and VIL = 0.8V (max) at +5V, scaling to VIH = 2.0V / VIL = 0.4V at +3V. Analog signal range extends rail-to-rail (0V to V+), with off-isolation of -67dB at 1MHz and total harmonic distortion of 0.015% over 20Hz–20kHz.
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 up to ±100mA continuous current. |
| RON Matching | 0.4Ω max between channels - maintains consistent gain and signal amplitude across all four multiplexer paths. |
| Turn-On Time (tON) | 18ns max - enables high-speed signal routing in broadband communications and sampling systems. |
| Off-Isolation | -67dB at 1MHz - suppresses unwanted coupling between enabled and disabled channels in dense PCB layouts. |
| Crosstalk | -114dB at 1MHz - prevents interference between adjacent switched signals in multi-channel audio/video applications. |
| Supply Range | +1.8V to +5.5V single supply - supports direct integration into modern low-voltage microcontroller and FPGA I/O domains. |
| Logic Compatibility | TTL/CMOS thresholds at +5V - allows direct interfacing with legacy 5V logic without level-shifting circuitry. |
Pinout & Package
MAX4674ESE+T is housed in a 16-pin narrow SO (SOIC-N) package measuring 9.9mm × 3.9mm × 1.5mm, with gull-wing leads and industry-standard 1.27mm pitch. The exposed pad variant is not used in this SO package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC1) | Normally Closed Terminal - Channel 1 | No internal connection; must be left unconnected or tied to GND for mechanical stability. |
| 2 (NO1) | Normally Open Terminal - Channel 1 | Signal path connected to COM1 only when A0 = 0 and EN = low; forms one side of 2:1 mux pair. |
| 3 (COM1) | Common Terminal - Channel 1 | Central analog node shared between NO1 and NC1; carries routed signal to downstream circuitry. |
| 4 (NC2) | Normally Closed Terminal - Channel 2 | No internal connection; unused terminal for Channel 2; requires no external biasing. |
| 5 (NO2) | Normally Open Terminal - Channel 2 | Active signal path for Channel 2 when A0 = 0 and EN = low; electrically isolated when disabled. |
| 6 (COM2) | Common Terminal - Channel 2 | Second independent analog common node; supports simultaneous dual-path routing with COM1. |
| 7 (GND) | Ground Reference | Primary return path for analog and digital currents; must be low-impedance and decoupled near V+ pin. |
| 8 (COM3) | Common Terminal - Channel 3 | Third analog common node; enables three independent 2:1 multiplexing functions in one IC. |
| 9 (NO3) | Normally Open Terminal - Channel 3 | Switched output for Channel 3; selected when A0 = 1 and EN = low; supports high-frequency signal integrity. |
| 10 (NC3) | Normally Closed Terminal - Channel 3 | No internal connection; reserved for future compatibility; must remain floating or grounded. |
| 11 (COM4) | Common Terminal - Channel 4 | Fourth independent analog common; completes quad configuration for multi-source sensor or DAC routing. |
| 12 (NO4) | Normally Open Terminal - Channel 4 | Final switched output; activated under same control logic as NO1–NO3; shares identical RON specs. |
| 13 (NC4) | Normally Closed Terminal - Channel 4 | No internal connection; unused terminal; no electrical function in MAX4674ESE+T implementation. |
| 14 (EN) | Enable Input (Active Low) | Global shutdown control: pulls all switches open when high; permits channel selection only when low. |
| 15 (A0) | Address Select Input | Selects between NO/NC pairs per channel: A0 = 0 routes COMx–NOx; A0 = 1 routes COMx–NCx (NCx unconnected). |
| 16 (V+) | Positive Supply Voltage | Single power rail for analog and digital sections; must be bypassed with ≥0.1µF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from 0V to V+, eliminating clipping in low-voltage data-acquisition 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 | 4Ω RON at +5V but requires dual ±15V supplies or +12V single supply; no 1.8V operation. | Targeted at high-voltage industrial test equipment, not portable low-voltage systems. | Choose ADG1414BRUZ only if system already uses ±15V rails and requires higher breakdown voltage (>30V). |
| TS3A4751PWR | 0.9Ω RON at +3.3V but lacks guaranteed RON matching (0.4Ω max) and has higher 15pC charge injection. | Better for cost-sensitive consumer audio; less suitable for precision metrology requiring matched channels. | Prefer TS3A4751PWR when ultra-low RON dominates over matching and leakage specs in battery-powered designs. |
Compared with ADG1414BRUZ and TS3A4751PWR, MAX4674ESE+T uniquely balances 1.8V operability, guaranteed RON matching, and sub-nA leakage-making it optimal for portable medical sensors and multi-channel data loggers where supply headroom and DC accuracy are constrained.

FAQ
What is the maximum supply voltage rating for MAX4674ESE+T?
The absolute maximum supply voltage (V+) for MAX4674ESE+T is +6V. Operation beyond +5.5V risks permanent damage. The device is characterized for reliable performance from +1.8V to +5.5V, with guaranteed RON and timing specs across that range. Exceeding +6V violates Absolute Maximum Ratings and may degrade ESD diode integrity.
Does MAX4674ESE+T support rail-to-rail analog signal switching?
Yes, MAX4674ESE+T supports true rail-to-rail analog signal switching: the analog signal range spans from 0V to V+, with no headroom requirement. This is confirmed in Electrical Characteristics tables for both +5V and +3V supplies. Signal integrity remains preserved across the full range due to optimized CMOS switch design and internal level-shifting.
What is the function of the NC pins on MAX4674ESE+T?
The NC pins (pins 1, 4, 10, 13) on MAX4674ESE+T are Not Connected internally - they serve no electrical function. Per Maxim's Pin Description table, these terminals are reserved for mechanical compatibility and future variants. They must be left floating or tied to GND for PCB stability; connecting them to active signals may cause unintended coupling or layout parasitics.
Can MAX4674ESE+T operate with 3.3V logic control while powered from a 5V supply?
Yes, MAX4674ESE+T supports mixed-voltage operation: digital inputs A0 and EN tolerate voltages up to +5.5V regardless of V+ level. When V+ = +5V, VIH = 2.4V (min) and VIL = 0.8V (max) - fully compatible with standard 3.3V CMOS logic outputs. This eliminates need for external level shifters in FPGA or MCU interfacing.
What is the thermal resistance (θJA) of the MAX4674ESE+T SO package?
The junction-to-ambient thermal resistance (θJA) for MAX4674ESE+T in the 16-pin narrow SO package is 80°C/W, derived from its 640mW maximum power dissipation at +70°C ambient and 8mW/°C derating rate. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with added copper pour and thermal vias beneath the package body.
