Product details
Overview
MAX4660EUA+T from Maxim Integrated is a thermally enhanced 8-pin µMAX-EP SPDT analog switch designed for high-current signal routing in industrial and telecom systems. It delivers 150mA continuous current, 25Ω max on-resistance at ±15V, rail-to-rail signal handling, and operates from ±4.5V to ±20V dual supplies or +9V to +40V single supply - enabling robust relay replacement in xDSL modems and PBX systems.
For engineers reviewing the MAX4660EUA+T datasheet, MAX4660EUA+T pinout, MAX4660EUA+T application, or MAX4660EUA+T equivalent, key selection criteria include verified 150mA continuous current capability, exposed paddle thermal performance, break-before-make timing (≤10ns), and compatibility with ±15V/±20V or +12V supply configurations.
Technical Context
The MAX4660EUA+T implements a CMOS SPDT architecture with parallel N-channel and P-channel MOSFETs per switch path, enabling rail-to-rail conduction and eliminating body-diode voltage drop limitations. Its proprietary gate-drive sensing circuit maintains low leakage (<1nA off-leakage at +25°C) and stable RON flatness (≤1.5Ω at ±15V) across the full analog signal range.
It supports asymmetrical dual-supply operation (e.g., V+ = +15V, V− = −5V) within a 40V total range and features TTL/CMOS-compatible logic input (VIH = 2.4V, VIL = 0.8V). Dynamic performance includes 225MHz −3dB bandwidth, <200ns transition time, and −70dB off-isolation at 1MHz - critical for audio routing and test equipment signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 25Ω max at ±15V - ensures minimal voltage drop and power loss when switching 150mA loads. |
| Continuous Current | ±150mA - enables direct replacement of electromechanical relays in high-duty-cycle applications. |
| Supply Range | ±4.5V to ±20V dual or +9V to +40V single - supports wide-range industrial and telecom power architectures. |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor or precision audio paths. |
| Transition Time | 200ns max - meets timing requirements for fast-switching test instrumentation and communication multiplexing. |

Pinout & Package
The MAX4660EUA+T is housed in an 8-pin thermally enhanced µMAX-EP package (U8E-2) with an exposed paddle electrically isolated from internal circuitry and recommended to be connected to V+ for optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 COM | Analog Switch Common | Shared terminal connecting to either NC or NO based on logic state; carries full switched current. |
| 2 NC | Normally Closed Terminal | Connected to COM when IN = low; provides default signal path in fail-safe configurations. |
| 3 GND | Ground Reference | Logic ground reference; must be connected before V+ and V− per sequencing guidelines. |
| 4 V+ | Positive Supply Input | Accepts +9V to +40V (single) or up to +20V (dual); powers internal logic and switch circuitry. |
| 5 N.C. | No Connection | Internally unconnected; no external connection required or recommended. |
| 6 IN | Digital Control Input | TTL/CMOS-compatible logic input (VIH = 2.4V, VIL = 0.8V); controls NC/NO switching state. |
| 7 V− | Negative Supply Input | Accepts −4.5V to −20V (dual); enables bipolar rail-to-rail analog signal handling. |
| 8 NO | Normally Open Terminal | Connected to COM when IN = high; used for active signal selection in multiplexer topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±15V op-amp interfaces and audio line drivers. |
| Thermally enhanced µMAX-EP | Exposed paddle improves thermal resistance by >30% vs. standard µMAX - sustains 150mA continuous current at +85°C ambient. |
| 1.5Ω max RON flatness | Ensures consistent gain and minimal THD (0.005%) across full signal swing - critical for high-fidelity audio routing. |
| No VL supply required | Eliminates need for separate logic supply - simplifies BOM and PCB layout in space-constrained designs. |
| 200mA peak current capability | Handles pulsed loads (1ms, 10% duty cycle) such as solenoid drivers or burst-mode test signals without latch-up. |

FAQ
What is the maximum continuous current rating for MAX4660EUA+T?
The MAX4660EUA+T is rated for ±150mA continuous current through the COM, NO, and NC terminals under specified thermal conditions. This rating applies at TA = −40°C to +85°C with proper PCB thermal design, including connection of the exposed paddle to V+ to maximize heat dissipation. Exceeding this current may cause thermal shutdown or permanent damage per absolute maximum ratings.
Does MAX4660EUA+T require a separate logic supply voltage (VL)?
No, the MAX4660EUA+T does not require a separate VL supply. Its digital control input (IN) is fully TTL/CMOS compatible and operates directly from the main V+ and V− supplies. The internal level-shifting circuitry eliminates the need for an auxiliary logic rail - simplifying power architecture and reducing component count in compact designs.
Can MAX4660EUA+T operate with asymmetric dual supplies, such as +15V and −5V?
Yes, the MAX4660EUA+T supports asymmetric dual-supply operation as long as the total voltage difference between V+ and V− remains within the 40V absolute maximum rating. For example, +15V and −5V (20V total) is valid and maintains full rail-to-rail analog signal range from −5V to +15V - useful for interfacing with mixed-voltage system blocks.
What is the function of Pin 5 (N.C.) on MAX4660EUA+T?
Pin 5 on the MAX4660EUA+T is designated N.C. (No Connection) and is internally unconnected. It must remain unconnected on the PCB - no trace, via, or component should be attached. Connecting Pin 5 risks unintended coupling, noise injection, or violation of internal isolation boundaries defined in the silicon layout.
How does the exposed paddle on MAX4660EUA+T affect thermal performance?
The exposed paddle on the MAX4660EUA+T significantly lowers thermal resistance: when soldered to a V+-connected copper plane, junction-to-board θJB drops to ~25°C/W (vs. ~55°C/W for standard µMAX). This enables sustained 150mA operation at +85°C ambient - confirmed in the Absolute Maximum Ratings table and validated in thermal characterization data for the U8E-2 package.
