Product details
Overview
The MAX4614EUD+ from Analog Devices is a quad, low-voltage, high-speed, single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, 10Ω max on-resistance at +5V, 12ns turn-on time, and rail-to-rail signal handling from V+ to GND - used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4614EUD+ datasheet, MAX4614EUD+ pinout, MAX4614EUD+ application, or MAX4614EUD+ equivalent, key selection criteria include guaranteed channel matching (≤1Ω), sub-6nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and -40°C to +85°C extended temperature operation.
Technical Context
This CMOS analog switch operates from a single +2V to +5.5V supply and features matched on-resistance (≤1Ω max between channels) and flat on-resistance (≤1Ω max over full signal range), enabling precision signal routing without gain error or crosstalk-induced distortion. Its bidirectional COM–NO architecture supports rail-to-rail analog signals up to V+.
Digital inputs meet TTL/CMOS thresholds (+0.8V low, +2.4V high at +5V), ensuring reliable control across mixed-signal systems. The device delivers 70MHz on-channel bandwidth and -96dB crosstalk at 100kHz, making it suitable for high-fidelity audio and fast data sampling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 10Ω at +5V supply - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| On-resistance match | ≤1Ω max between channels - enables precise multi-channel signal switching without gain mismatch |
| Turn-on time | 12ns typical - supports high-speed multiplexing in data acquisition and communication circuits |
| Off-leakage current | 6nA max at +85°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces |
| Analog signal range | Rail-to-rail (GND to V+) - allows full utilization of supply headroom in single-supply systems |
| Logic compatibility | TTL/CMOS thresholds (+0.8V / +2.4V at +5V) - eliminates need for level-shifting in microcontroller-controlled designs |
| Supply voltage range | +2V to +5.5V - supports operation from Li-ion batteries (3.0–3.7V) and standard 3.3V/5V rails |
Pinout & Package
MAX4614EUD+ is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.1mm), optimized for space-constrained portable and industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - connect only when corresponding INx is HIGH; bidirectional signal path |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as input/output junctions for each SPST switch; rail-to-rail capable |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive NOx-COMx connection state (LOW = OFF, HIGH = ON) |
| 7 | GND | Ground reference for analog and digital circuitry - must be low-impedance return path to minimize noise coupling |
| 14 | V+ | Positive supply pin - powers internal CMOS switches and logic; accepts +2V to +5.5V with no external regulation required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - critical for single-supply sensor and audio interfaces |
| Guaranteed on-resistance flatness | ≤1Ω variation over full signal range - prevents harmonic distortion in AC-coupled or wide-dynamic-range applications |
| Low charge injection (6.5pC) | Minimizes voltage glitch on sampled nodes - essential for precision sample-and-hold and ADC front-end switching |
| High off-isolation (-85dB) | Reduces signal bleed-through between inactive channels - improves channel-to-channel separation in multiplexers |
| 14ns max turn-on time over temp | Ensures timing consistency across -40°C to +85°C - enables deterministic switching in automotive and industrial environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615EUD+ | Four normally closed (NC) switches instead of NO; identical RON, timing, and leakage specs | Suitable where default-closed signal paths are required (e.g., fail-safe sensor monitoring) | Select MAX4615EUD+ only when NC behavior is functionally required; not pin-compatible for NO-replacement |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V or +5V single), 16-TSSOP package | Targeted at higher-precision instrumentation; supports dual-supply operation and lower THD (0.0003%) | Choose ADG1414BRUZ for sub-1Ω RON matching and dual-supply flexibility; requires PCB layout change |
Compared with MAX4614EUD+, MAX4615EUD+ provides inverse switch logic but identical performance envelope, while ADG1414BRUZ trades package compatibility for superior RON flatness and dual-supply support - both require functional validation before substitution.

FAQ
What is the maximum supply voltage rating for the MAX4614EUD+?
The MAX4614EUD+ has an absolute maximum supply voltage of +6V, but its specified operating range is +2V to +5.5V. Operating above +5.5V risks permanent damage and invalidates parametric guarantees; design margins should maintain V+ ≤ +5.5V under all conditions including transient spikes. The MAX4614EUD+ datasheet specifies electrical characteristics only within the +2V to +5.5V range.
Does the MAX4614EUD+ support rail-to-rail analog signal switching?
Yes, the MAX4614EUD+ supports true rail-to-rail analog signal handling from GND to V+, as confirmed by its analog signal range specification (0V to V+) and internal CMOS architecture. This allows full utilization of the supply voltage range for both input and output signals without clipping or distortion, which is essential in single-supply portable applications.
What is the guaranteed on-resistance matching between channels for the MAX4614EUD+?
The MAX4614EUD+ guarantees on-resistance matching of ≤1Ω maximum between any two channels at temperatures from -40°C to +85°C, measured under V+ = +4.5V, ICOM = 10mA, and VNO = VNC = 3V. This tight matching ensures consistent gain and minimal channel-to-channel error in multiplexed measurement systems.
Can the MAX4614EUD+ operate from a +3.3V supply?
Yes, the MAX4614EUD+ is fully specified for +3.3V operation: on-resistance is guaranteed ≤20Ω max, turn-on time ≤15ns, and off-leakage remains ≤10nA at +85°C. Its TTL/CMOS-compatible logic thresholds (+0.8V low, +2.0V high at +3.3V) ensure reliable interface with 3.3V microcontrollers without level shifters.
Is the MAX4614EUD+ pin-compatible with the 74HC4066?
Yes, the MAX4614EUD+ is explicitly pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches, sharing identical 14-pin TSSOP pinout, terminal functions, and logic polarity. This allows direct replacement in existing designs while delivering lower on-resistance, faster switching, and improved leakage performance.
