Product details
Overview
The MAX4614CSD+ from Analog Devices is a quad, low-voltage, high-speed SPST analog switch with four normally open (NO) channels, designed for rail-to-rail signal routing in battery-powered and precision analog systems. It delivers 10Ω max on-resistance at +5V, 12ns turn-on time, <6nA off-leakage at +85°C, and TTL/CMOS logic compatibility - enabling clean audio/video switching and low-distortion data acquisition.
For engineers reviewing the MAX4614CSD+ datasheet, MAX4614CSD+ pinout, MAX4614CSD+ application, or MAX4614CSD+ equivalent, this device is selected for low-noise, high-bandwidth analog path control where matched channel resistance, minimal charge injection (6.5pC), and sub-10ns switching are critical in portable instrumentation and communication interfaces.
Technical Context
The MAX4614CSD+ implements a CMOS transmission-gate architecture optimized for single-supply operation from +2V to +5.5V. Its digital inputs feature fixed 0.8V/2.4V logic thresholds - ensuring reliable TTL/CMOS interoperability without level-shifting when powered from +5V.
All four NO switches share identical electrical behavior: on-resistance flatness ≤1Ω over 0V to V+, matching ≤1Ω between channels, and guaranteed rail-to-rail analog signal handling (V+ to GND). Off-isolation exceeds -85dB at 100kHz, and crosstalk remains below -96dB between any two channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports direct integration into 3.3V and 5V systems without external regulators |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths |
| On-Resistance Match | ≤1Ω max between channels - enables accurate differential or ratiometric measurements across switched paths |
| Turn-On / Turn-Off Time | 12ns / 10ns at +5V - allows high-speed multiplexing in data-acquisition and sampling applications |
| Off-Leakage Current | 6nA max at +85°C - preserves accuracy in high-impedance sample-and-hold or battery-monitoring circuits |
| Charge Injection | 6.5pC - limits voltage glitch on sampled nodes, critical for 12-bit+ ADC front-ends |
| Bandwidth | 70MHz - supports composite video, USB 1.1 signaling, and broadband test equipment switching |
Pinout & Package
MAX4614CSD+ is housed in a 14-pin narrow SO (SOIC-N) package, 3.9mm wide, with standard 1.27mm pitch and gull-wing leads - compatible with automated SMT assembly and IPC-7351B footprint SN14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog 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 |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive NOx closed when HIGH (logic 1) |
| 7 | GND | Analog/digital ground reference - must be low-impedance return for signal integrity and leakage control |
| 14 | V+ | Positive supply - powers internal CMOS switches and logic; must be stable and decoupled per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates level-shifting in single-supply systems like portable medical sensors |
| Matched on-resistance (≤1Ω) | Enables precise gain/offset calibration across multiple channels in multichannel DAQ or audio mixer ICs |
| Low charge injection (6.5pC) | Reduces hold-step error in sample-and-hold circuits, preserving DC accuracy for 16-bit ADCs |
| High off-isolation (-85dB) | Minimizes signal coupling between inactive channels - essential for RF test fixtures and ATE switching matrices |
| TTL/CMOS logic compatibility | Eliminates need for external level translators when interfacing with microcontrollers or FPGAs operating at +5V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615CSD+ | Four normally closed (NC) switches instead of NO - complementary logic polarity and default state | Suitable where fail-safe closure is required (e.g., safety interlock bypass), not direct replacement for NO function | Select MAX4615CSD+ only when circuit requires default-closed behavior; pinout and timing match exactly but logic inversion changes system control flow |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V or +5V to +16.5V), 16-pin TSSOP | Supports dual-supply and higher-voltage industrial signal chains; not pin-compatible or drop-in | Choose ADG1414BRUZ for ±5V operation or lower RON tolerance; requires PCB redesign due to different pin count and layout |
Compared with MAX4615CSD+, the MAX4614CSD+ provides active-high NO control ideal for enable-driven architectures, while ADG1414BRUZ trades speed and package compatibility for broader voltage range and lower on-resistance - making MAX4614CSD+ optimal for compact, battery-efficient 3.3V/5V systems demanding tight matching and fast settling.

FAQ
What is the maximum supply voltage rating for the MAX4614CSD+?
The MAX4614CSD+ has an absolute maximum supply voltage of +6V, but its specified operational range is +2V to +5.5V. Operating above +5.5V risks exceeding safe internal bias conditions and may increase leakage or reduce reliability. The device is fully characterized and guaranteed at +5V, +3.3V, and +2.5V supplies - with on-resistance rising predictably at lower voltages (e.g., 60Ω max at +2.5V).
Does the MAX4614CSD+ support rail-to-rail analog signal operation?
Yes, the MAX4614CSD+ supports true rail-to-rail analog signal handling: signals at COMx and NOx terminals can swing from GND to V+ without distortion or clipping. This is enabled by its CMOS transmission-gate design and internal level-shifting circuitry. The datasheet specifies analog signal range as 0V to V+ under all operating conditions, and absolute maximum ratings allow brief excursions to -0.3V and V+ + 0.03V due to internal ESD clamps.
How does the on-resistance matching specification apply to the MAX4614CSD+?
The MAX4614CSD+ guarantees on-resistance matching of ≤1Ω maximum between any two channels at +25°C and ≤1.2Ω over the full 0°C to +70°C temperature range. This means the difference between the highest and lowest RON values measured across all four switches stays within that bound - critical for applications like programmable gain amplifiers or differential sensor readouts where ratio-metric accuracy matters more than absolute RON value.
Can the MAX4614CSD+ be used with a 3.3V logic controller?
Yes, the MAX4614CSD+ is fully compatible with 3.3V logic controllers. Its digital inputs have fixed 0.8V low and 2.4V high thresholds - well within the VOH/VOL specs of standard 3.3V CMOS outputs (typically ≥2.4V for HIGH, ≤0.4V for LOW). No level-shifting is needed, and the device draws only 1µA supply current, minimizing load on the controller's GPIO drivers.
What is the thermal performance of the MAX4614CSD+ in its narrow SO package?
The MAX4614CSD+ in the 14-pin narrow SO package has a thermal resistance θJA of 125°C/W and a derating factor of 8.00mW/°C above +70°C. At maximum rated ambient temperature (+70°C), its continuous power dissipation is 640mW. In typical applications drawing <100µA supply current and switching low-current analog signals, self-heating remains negligible - ensuring stable RON and leakage performance across the full commercial temperature range.
