Product details
Overview
MAX4614CSD+T from Analog Devices is a quad, low-voltage, high-speed 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 audio routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4614CSD+T datasheet, MAX4614CSD+T pinout, MAX4614CSD+T application, or MAX4614CSD+T equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), sub-10nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and SOIC narrow package thermal performance (640mW at +70°C).
Technical Context
The MAX4614CSD+T implements CMOS transmission-gate architecture with matched P/N channel pairs per switch, enabling flat on-resistance (<1Ω variation) across 0V to V+ signal range. Its digital control inputs feature fixed 0.8V/2.4V thresholds-ensuring robust TTL/CMOS interoperability without level-shifting when powered from +5V.
Each NO switch operates bidirectionally between COM and NO terminals, supporting analog signals up to V+ + 0.03V (clamped by internal diodes). The device draws only 1µA supply current and maintains <6nA COM off-leakage over full industrial temperature range (0°C to +70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 10Ω at +5V supply - ensures minimal signal attenuation in precision analog paths |
| On-resistance match | ≤1Ω max between channels - enables accurate gain/offset matching in multi-channel signal routing |
| Turn-on time | 12ns typical - supports high-speed multiplexing in sampling and communication circuits |
| Off-leakage current | 6nA max at +85°C - preserves signal integrity in high-impedance sample-and-hold nodes |
| Analog signal range | 0V to V+ - allows rail-to-rail operation without external biasing in single-supply systems |
| Logic compatibility | TTL/CMOS thresholds (0.8V/2.4V) - eliminates need for interface logic when driven by standard microcontrollers |
| Supply voltage range | +2V to +5.5V - supports direct integration into Li-ion (3.3V/3.7V) and legacy 5V systems |
Pinout & Package
MAX4614CSD+T is housed in a 14-pin narrow SOIC (SOICN) package with 1.27mm pitch, rated for 640mW power dissipation at +70°C (derated 8.00mW/°C above).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - connect to signal sources only when corresponding INx is HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common analog I/O ports - bidirectional path shared between NO and internal switch matrix |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - active-HIGH logic controls NO switch state (LOW = OFF, HIGH = ON) |
| 7 | GND | Ground reference - required for logic threshold definition and analog return path |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; must be applied before analog/logic signals |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports 0V to V+ analog swing without clipping or distortion in single-supply configurations |
| Guaranteed on-resistance flatness | ≤1Ω variation over full signal range - minimizes harmonic distortion in audio and instrumentation paths |
| Low charge injection | 6.5pC typical - reduces voltage glitch in sample-and-hold and ADC front-end applications |
| High off-isolation | -85dB at 100kHz - prevents crosstalk between inactive channels in dense multiplexer layouts |
| Ultra-low leakage | ≤6nA COM off-leakage at +85°C - maintains accuracy in high-impedance sensor interfaces |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615CSD+T | Four normally closed (NC) switches instead of NO; identical RON, timing, and leakage specs | Suitable where default-closed signal path is required (e.g., fail-safe sensor monitoring) | Select MAX4615CSD+T only when NC behavior is mandatory; not drop-in for NO-based designs. |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V to +16.5V), 16-TSSOP package | Targeted at higher-voltage industrial automation, not optimized for sub-5V battery operation | Choose ADG1414BRUZ for dual-supply or >5V systems; MAX4614CSD+T preferred for 2–5.5V portables. |
Compared with MAX4615CSD+T, the MAX4614CSD+T provides normally open behavior essential for power-gating and default-off routing; versus ADG1414BRUZ, it delivers lower on-resistance and smaller footprint for space-constrained 3.3V/5V designs, but lacks extended voltage range.

FAQ
What is the maximum supply voltage rating for MAX4614CSD+T?
The absolute maximum supply voltage for MAX4614CSD+T is +6V, but the recommended operating range is +2V to +5.5V. Exceeding +6V risks permanent damage due to internal diode clamping limits. At +5.5V, on-resistance remains within spec (≤10Ω), and leakage stays below 6nA at +85°C. Always apply V+ before analog or logic signals to avoid latch-up.
Does MAX4614CSD+T support rail-to-rail analog signal operation?
Yes, MAX4614CSD+T supports true rail-to-rail analog signal handling from 0V to V+. The COM, NO, and NC terminals operate across the full supply range, with internal protection diodes clamping signals to V+ + 0.03V and GND − 0.3V. This enables direct interfacing with op-amps and ADCs in single-supply configurations without level-shifting circuitry.
How does the on-resistance of MAX4614CSD+T vary with supply voltage?
MAX4614CSD+T on-resistance increases as supply voltage decreases: 10Ω max at +5V, 20Ω max at +3V, and 60Ω max at +2.5V (all measured at TA = +25°C). This voltage dependence is inherent to CMOS switch design. For stable RON, maintain V+ ≥ 4.5V; below 3V, verify signal integrity in high-precision paths using the flatness spec (≤1Ω variation over signal range).
Can MAX4614CSD+T be used with 3.3V logic controllers?
Yes, MAX4614CSD+T is fully compatible with 3.3V logic controllers. Its input thresholds are fixed at +0.8V (VIL) and +2.4V (VIH), so a 3.3V GPIO output (typically 0V/3.3V) meets both conditions with margin. Input current is <10nA, imposing negligible load. No level shifter is needed-direct connection to microcontroller pins is supported.
What is the thermal performance of the narrow SOIC package in MAX4614CSD+T?
The MAX4614CSD+T uses a 14-pin narrow SOIC package with 640mW maximum power dissipation at +70°C, derated at 8.00mW/°C above that temperature. At +85°C ambient, usable power drops to 520mW. This thermal profile supports continuous operation in compact enclosures without forced air, provided PCB copper area meets SOICN layout guidelines (e.g., 1-inch² thermal pad per side).
