Product details
Overview
MAX4615EUD+T from Analog Devices is a quad, high-speed, single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, designed for low-voltage signal routing in precision analog paths. It features 10Ω max on-resistance at +5V, 1Ω max channel-to-channel on-resistance match, and rail-to-rail signal handling from V+ to GND. Used in battery-powered audio routing and low-voltage data-acquisition systems where leakage and switching speed are critical.
For engineers reviewing the MAX4615EUD+T datasheet, MAX4615EUD+T pinout, MAX4615EUD+T application, or MAX4615EUD+T equivalent, key selection criteria include guaranteed 12ns tON/10ns tOFF timing, <6nA off-leakage at +85°C, 14-pin TSSOP package compatibility, and NC-switch topology for fail-safe signal continuity.
Technical Context
The MAX4615EUD+T implements CMOS transmission-gate architecture optimized for low-voltage operation (2V to 5.5V), with TTL/CMOS-compatible logic thresholds (0.8V/2.4V at +5V). Its four independent NC switches share a common V+ supply and ground reference, enabling simultaneous control of multiple analog paths without interaction.
All channels exhibit matched on-resistance (≤1Ω max difference) and flat on-resistance (≤1Ω variation over full signal range), ensuring consistent gain and minimal harmonic distortion (<0.034% THD) across the 0–20kHz audio band. Off-isolation exceeds –85dB at 100kHz, supporting clean multiplexing in sensitive measurement circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports direct integration into Li-ion battery (3.0–3.7V) and USB-powered (5V) systems |
| On-Resistance (max) | 10Ω at +5V - ensures ≤0.5% gain error in 2kΩ impedance interfaces |
| On-Resistance Match | 1Ω max between channels - enables precise ratiometric measurements in multi-channel ADC front-ends |
| Off-Leakage Current | 6nA at +85°C - preserves accuracy in high-impedance sample-and-hold nodes (>10MΩ) |
| Switching Speed | tON = 12ns, tOFF = 10ns - supports >10MHz multiplexed signal sampling without settling delay |
| Analog Signal Range | Rail-to-rail (GND to V+) - eliminates level-shifting circuitry for unipolar sensor outputs |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) - allows direct interface to microcontroller GPIOs without level translators |
Pinout & Package
MAX4615EUD+T is housed in a 14-pin TSSOP package (3.0mm × 4.4mm, 0.65mm pitch), rated for –40°C to +85°C operation and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - maintain conductive path when INx = LOW; bidirectional signal routing |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - connect to signal source/load; shared reference for all four switches |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - active-low logic: LOW = NC path closed, HIGH = NC path open |
| 7 | GND | Analog/digital ground reference - must be low-impedance connection to minimize crosstalk and offset |
| 14 | V+ | Positive supply - powers analog core and logic; decoupling capacitor (100nF) required at pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports full V+ to GND analog swing without clipping - eliminates external biasing in sensor interfaces |
| Guaranteed on-resistance flatness | ≤1Ω variation across entire signal range - ensures linear gain response in variable-gain amplifiers |
| Low charge injection (6.5pC) | Minimizes voltage glitch on sampled nodes - critical for 12-bit+ SAR ADC front-ends |
| High off-isolation (–85dB) | Reduces crosstalk between adjacent channels - enables reliable 4:1 analog multiplexing |
| Pin compatibility with 74HC4066/MAX4610 | Drop-in replacement in legacy designs - no PCB layout changes required for upgrade path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615EUD+ | Same die, tape-and-reel vs. cut-tape packaging; identical electrical specs and thermal rating | No functional difference; used interchangeably in SMT production | Select MAX4615EUD+T for automated pick-and-place; MAX4615EUD+ for hand-solder prototyping |
| ADG1414BRUZ | Higher RON (1.8Ω typ), wider supply (±15V dual or +5V single), 16-pin TSSOP | Supports bipolar signals and higher voltage rails; not pin-compatible | Choose ADG1414BRUZ only when ±12V signal handling or lower RON is required; requires PCB redesign |
Compared with MAX4615EUD+T, MAX4615EUD+ offers identical performance in different packaging, while ADG1414BRUZ provides enhanced voltage range and lower on-resistance at the cost of pin incompatibility and larger footprint - making MAX4615EUD+T optimal for space-constrained, low-voltage, NC-default routing.

FAQ
What is the maximum supply voltage rating for MAX4615EUD+T?
The MAX4615EUD+T has an absolute maximum supply voltage of +6V, but its specified operating range is +2V to +5.5V. Operating above +5.5V risks exceeding safe junction temperature and may cause permanent damage. For reliable long-term operation in industrial environments, Analog Devices recommends staying within the +2V to +5.5V range, with +5V being the most commonly used supply for optimal on-resistance and switching speed in the MAX4615EUD+T.
Does MAX4615EUD+T support rail-to-rail analog signal operation?
Yes, the MAX4615EUD+T supports true rail-to-rail analog signal handling from GND to V+, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables. This means analog signals applied to COMx, NCx, or NOx terminals can swing continuously between the device's ground and positive supply rails without clipping or degradation - a key feature enabling direct interfacing with unbuffered sensors and DAC outputs without external level-shifting circuitry in the MAX4615EUD+T.
What is the logic polarity of the control inputs on MAX4615EUD+T?
The control inputs (IN1–IN4) on the MAX4615EUD+T are active-low: a logic LOW (≤0.8V) closes the NC switch path, while a logic HIGH (≥2.4V at +5V supply) opens it. This behavior is explicitly defined in the Pin Configurations/Truth Tables section and applies across the full –40°C to +85°C temperature range. The MAX4615EUD+T does not invert logic; its NC topology inherently provides fail-safe continuity when control signals are inactive or undriven.
Can MAX4615EUD+T be used with a +3.3V supply?
Yes, the MAX4615EUD+T is fully specified and characterized for +3.3V operation. At +3.3V, its typical on-resistance is 20Ω (max 25Ω), tON/tOFF are 15ns/12ns, and off-leakage remains ≤10nA over temperature. These parameters are verified in the Electrical Characteristics table for +3.3V supply conditions. Using +3.3V aligns with modern low-power microcontrollers and FPGAs, making the MAX4615EUD+T suitable for mixed-signal systems where supply voltage scaling is essential.
Is MAX4615EUD+T pin-compatible with the 74HC4066?
Yes, the MAX4615EUD+T is explicitly stated as pin-compatible with the industry-standard 74HC4066 and MAX4610 in the General Description. All four analog switch terminals (COM/NC), control inputs (IN), power (V+), and ground (GND) occupy identical positions in the 14-pin TSSOP package. This allows direct substitution without PCB modification, though designers should verify that the NC functionality of MAX4615EUD+T matches the intended use case - unlike the 74HC4066's NO-only topology.
