Product details
Overview
MAX4677EUE from Maxim Integrated is a quad, normally closed (NC), SPST analog switch IC designed for precision signal routing in rail-to-rail systems. It delivers 1.6Ω max on-resistance, 0.3Ω max channel-to-channel RON matching, and −65dB off-isolation at 1MHz - enabling low-distortion audio, test equipment, and data-acquisition signal paths with minimal crosstalk and charge injection.
For engineers reviewing the MAX4677EUE datasheet, MAX4677EUE pinout, MAX4677EUE application, or MAX4677EUE equivalent, key selection criteria include its dual ±2.7V to ±5.5V / single +2.7V to +11V supply flexibility, independent logic supply (VL), guaranteed NC configuration, and TSSOP-16 package compatibility with automated test and high-density PCB layouts.
Technical Context
The MAX4677EUE implements four independent CMOS SPST switches with normally closed topology, each featuring matched, flat on-resistance across the full analog signal range (−5V to +5V with dual supplies). Its internal architecture supports break-before-make isolation only in the MAX4679 variant - not applicable here - and relies on separate VL input for TTL/CMOS-compatible logic control independent of analog supply rails.
It operates with rail-to-rail analog signal handling, sub-100pC charge injection, and 66MHz −3dB bandwidth under dual-supply conditions. Off-leakage remains ≤0.1nA at +25°C, ensuring minimal signal corruption in high-impedance sensor or ADC front-end applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.6Ω max at ±5V supplies - ensures minimal voltage drop and power loss in precision analog paths. |
| RON Matching | 0.3Ω max between channels - critical for multi-channel instrumentation where gain/phase tracking matters. |
| Off-Isolation | −65dB at 1MHz - suppresses signal coupling between inactive and active channels in dense routing. |
| −3dB Bandwidth | 66MHz (dual supply) - supports video, fast DAC/ADC switching, and broadband communications signals. |
| Supply Range | Dual ±2.7V to ±5.5V or single +2.7V to +11V - enables interoperability with legacy ±5V and modern 3.3V/5V systems. |
| Logic Supply (VL) | +2.7V to V+ - allows independent level-shifting between digital controller and analog domain without external translators. |
| Charge Injection | 85pC - limits voltage glitch on sampled nodes, essential for sample-and-hold and multiplexed ADC interfaces. |
Pinout & Package
MAX4677EUE is housed in a 16-pin Thin Shrink Small Outline Package (TSSOP) with exposed pad (not thermally enhanced per datasheet), rated for −40°C to +85°C operation. Pin pitch is 0.65mm; body dimensions are 5.0mm × 4.4mm × 1.2mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low logic inputs controlling NC switch state; logic '0' closes path, '1' opens. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to load/sensor side in NC configuration. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - tied internally to COM when IN = 0; open when IN = 1. |
| 4 | V− | Negative supply rail; must be connected to GND for single-supply operation. |
| 5 | GND | Signal and power ground reference for analog and logic domains. |
| 12 | VL | Independent logic supply input - decouples digital interface voltage from analog rails. |
| 13 | V+ | Positive supply rail - sets upper analog signal limit and powers internal switch array. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ swing - preserves dynamic range in ±5V op-amp circuits and unipolar 0–10V industrial sensors. |
| Low 0.1nA off-leakage at +25°C | Minimizes error current in high-Z medical sensor front-ends and precision integrators. |
| TTL/CMOS logic compatibility | Accepts standard 0.8V/2.4V thresholds - interfaces directly with FPGA I/O banks and microcontroller GPIOs. |
| −84dB crosstalk at 1MHz | Prevents interference between adjacent switched audio or RF paths in multi-channel ATE fixtures. |
| Guaranteed NC topology | Ensures fail-safe closure during power loss or logic reset - required in safety-critical signal monitoring paths. |
Applications
| Automated Test Equipment (ATE) | Audio Signal Routing |
|---|---|
Use Scenario: Multiplexing DUT signals to measurement instruments in semiconductor test handlers. IC Role / Device Role / Timing Role: Quad NC switch isolating unused channels while maintaining low-RON continuity on active paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4678EUE | Quad NO (normally open) topology vs. MAX4677EUE's NC - complementary logic polarity and default state. | Suitable where default-open behavior is required (e.g., safety interlocks, power-gated signal paths). | Select MAX4678EUE only if system requires de-energized-open default; not interchangeable without logic inversion. |
| ADG1414BRUZ | Higher RON (1.8Ω typ), wider supply (±15V), no independent VL pin - uses VDD for logic and analog domains. | Better suited for high-voltage industrial I/O, but lacks VL flexibility and has higher leakage (1nA). | Choose ADG1414BRUZ for ±15V operation or when VL independence is unnecessary; MAX4677EUE preferred for low-leakage, mixed-supply designs. |
Compared with MAX4678EUE and ADG1414BRUZ, the MAX4677EUE uniquely combines guaranteed NC operation, ultra-low leakage, and independent logic supply - making it optimal for fail-safe, low-noise, multi-rail signal routing where default continuity and supply decoupling are mandatory.

FAQ
What is the maximum supply voltage range supported by the MAX4677EUE?
The MAX4677EUE operates from either dual supplies of ±2.7V to ±5.5V or a single supply of +2.7V to +11V. Absolute maximum ratings specify V+ to GND up to +12V and V− to GND down to −12V, but functional operation is guaranteed only within the specified ranges. Exceeding these may cause permanent damage.
Does the MAX4677EUE support rail-to-rail analog signal switching?
Yes, the MAX4677EUE supports rail-to-rail analog signal switching - meaning signals from V− to V+ can pass through the switch with minimal distortion. This is confirmed in both the General Description and Electrical Characteristics sections, and applies under both dual- and single-supply configurations.
What is the logic configuration of the MAX4677EUE - normally open or normally closed?
The MAX4677EUE is a quad normally closed (NC) analog switch. When logic input (INx) is low (0), the switch connects COMx to NCx; when INx is high (1), the path opens. This is explicitly defined in the General Description and Pin Configuration diagrams for MAX4677.
Can the MAX4677EUE be used with different logic and analog supply voltages?
Yes, the MAX4677EUE features a dedicated VL pin that accepts +2.7V to V+, allowing independent logic and analog supply domains. This enables interfacing with 1.8V or 3.3V controllers while powering the analog switch array from ±5V - a key advantage over fixed-VDD switches like the ADG1414.
What is the typical on-resistance matching between channels for the MAX4677EUE?
The MAX4677EUE guarantees ≤0.3Ω maximum on-resistance matching (∆RON) between any two channels at +25°C, and ≤0.5Ω over the full −40°C to +85°C temperature range. This tight matching is critical for applications requiring consistent gain or timing across multiple switched paths.
