Product details
Overview
MAX4661EAE+T from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling-designed for precision reed relay replacement in automated test equipment and data acquisition systems.
For engineers reviewing the MAX4661EAE+T datasheet, MAX4661EAE+T pinout, MAX4661EAE+T application, or MAX4661EAE+T equivalent, key selection criteria include guaranteed RON match (≤0.5Ω), low off-leakage (≤5nA at +85°C), break-before-make exclusion (NC-only topology), and SSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The MAX4661EAE+T implements CMOS-based transmission-gate architecture with independent logic-level control inputs (IN1–IN4) referenced to VL, enabling TTL/CMOS compatibility across full supply ranges. Each NC switch connects COM_ to NC_ when IN_ = 0V and disconnects when IN_ = logic high.
It features separate analog (V+, V−) and logic (VL) supply pins, allowing mixed-voltage system interfacing. Absolute maximum ratings support V+ to V− differential up to 44V, with internal ESD protection exceeding 2kV per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON match between channels | 0.5Ω max - enables matched gain/attenuation in multi-channel instrumentation |
| RON flatness | 0.5Ω max over ±10V signal range - maintains consistent channel performance across full input swing |
| Off-leakage current | 5nA max at +85°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces |
| Supply range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and wide-range test equipment rails |
| Logic compatibility | TTL/CMOS inputs with VL pin - decouples logic threshold from analog supply, simplifying mixed-domain control |
| ESD rating | >2kV HBM - enhances robustness during board handling and system integration |
Pinout & Package
MAX4661EAE+T is housed in a 16-pin shrink small-outline package (SSOP) with 0.65mm lead pitch, optimized for compact, high-channel-count PCB layouts in automated test and data acquisition modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs: logic low closes NC switch; referenced to VL |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path endpoints |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - connected to COM when IN = 0V |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation |
| 5 | GND | Ground reference for logic and substrate |
| 12 | VL | Logic supply input - sets input threshold independently of V+/V− |
| 13 | V+ | Positive analog supply - defines upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - essential for full-scale ADC front-ends and audio routing |
| Guaranteed RON match ≤0.5Ω | Enables precise channel-to-channel tracking in multiplexed sensor arrays or calibration circuits |
| Low charge injection (20pC typ) | Minimizes voltage glitch in sample-and-hold and switched-capacitor applications |
| High off-isolation (−56dB typ at 1MHz) | Reduces crosstalk between active and inactive channels in dense signal routing |
| Break-before-make excluded | NC-only topology eliminates transition overlap - prevents shorting during switching in safety-critical paths |
Applications
| Reed Relay Replacement | Test Equipment Signal Routing |
|---|---|

IC Role / Device Role / Timing Role: Fault-tolerant NC switch providing fail-safe default connection in case of control signal loss. Use Value: Ensures continuous signal path integrity during power-up, brownout, or controller reset - meeting DO-160 Section 20 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4662EAE+T | Four normally open (NO) configuration instead of NC; identical RON, leakage, and supply specs | Suitable where default-open safety state is required (e.g., power-down isolation) | Select MAX4662EAE+T when circuit requires open-circuit default behavior upon power loss or logic fault |
| ADG1414BRUZ | 4-channel, NO/NC configurable via EN pin; 1.3Ω max RON; requires ≥±5V dual supply only | Offers programmable switch type but lacks single-supply flexibility and guaranteed RON match spec | Choose ADG1414BRUZ only if dynamic NO/NC reconfiguration is needed and supply constraints permit |
Compared with MAX4662EAE+T, the MAX4661EAE+T provides fail-safe closed-path continuity during control failure; versus ADG1414BRUZ, it delivers broader supply range support and tighter RON matching for metrology-grade channel uniformity.

FAQ
What is the operating temperature range for the MAX4661EAE+T?
The MAX4661EAE+T is rated for −40°C to +85°C ambient operation, validated across all electrical parameters including on-resistance, leakage, and switching timing. This extended industrial temperature grade ensures reliable performance in avionics bays, factory-floor test racks, and outdoor data loggers where thermal cycling is routine. The SSOP package's thermal characteristics support sustained operation within this full range without derating.
Does the MAX4661EAE+T support single-supply operation?
Yes, the MAX4661EAE+T supports single-supply operation from +4.5V to +36V with V− tied to GND. In this configuration, it maintains rail-to-rail analog signal handling from 0V to V+, full RON specification (2.5Ω max), and logic compatibility via the dedicated VL pin. Single-supply use is confirmed in the Electrical Characteristics table under "Single Supply" conditions (V+ = +12V, V− = 0).
How does the MAX4661EAE+T differ from the MAX4663EAE+T?
The MAX4661EAE+T contains four normally closed (NC) switches only, whereas the MAX4663EAE+T integrates two NC and two NO switches with guaranteed break-before-make timing (5ns min). The MAX4661EAE+T has no break-before-make feature and cannot substitute for the MAX4663EAE+T in applications requiring sequential channel isolation. Their pinouts are identical, but logic polarity and functional behavior differ per channel group.
What is the maximum allowable voltage difference between V+ and V− for the MAX4661EAE+T?
The absolute maximum voltage difference between V+ and V− is 44V, as specified in the Absolute Maximum Ratings table. Exceeding this limit risks permanent damage. For reliable operation, the device is characterized across ±4.5V to ±20V dual supplies - meaning V+ − V− must remain ≤40V under normal use. This headroom accommodates transient spikes while preserving long-term reliability in high-voltage test fixtures.
Is the MAX4661EAE+T pin-compatible with other packages in the MAX466x family?
Yes, the MAX4661EAE+T in 16-pin SSOP shares identical pinout and functionality with the MAX4661EWE (16 Wide SO) and MAX4661EPE (16 Plastic DIP) variants. All three packages implement the same NC-switch topology, logic interface, and electrical specifications - enabling direct PCB footprint interchangeability where mechanical constraints allow. No redesign is needed when migrating between these packages.
