Product details
Overview
MAX4614ESD 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-designed for precision signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4614ESD datasheet, MAX4614ESD pinout, MAX4614ESD application, or MAX4614ESD equivalent, this device delivers tightly matched channel resistance (≤1Ω), sub-6nA off-leakage at +85°C, TTL/CMOS-compatible logic thresholds, and guaranteed performance across –40°C to +85°C industrial temperature range.
Technical Context
The MAX4614ESD implements CMOS transmission-gate architecture with independent digital control inputs (IN1–IN4) enabling individual channel switching. Each NO switch connects COMx to NOx when its input is HIGH, supporting bidirectional analog signals up to V+.
It operates from a single +2V to +5.5V supply with logic thresholds fixed at +0.8V (LOW) and +2.4V (HIGH) for robust TTL/CMOS compatibility. Signal integrity is preserved via low charge injection (6.5pC), high off-isolation (–85dB), and minimal crosstalk (–96dB) at 100kHz.
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 level-shifting |
| On-Resistance (max) | 10Ω at +5V - ensures minimal voltage drop and signal attenuation in low-level sensor/audio paths |
| On-Resistance Match | ≤1Ω max between channels - enables precise gain matching in multi-channel instrumentation |
| Turn-On / Turn-Off Time | 12ns / 10ns - allows high-speed multiplexing in data-acquisition and communication circuits |
| Off-Leakage Current | 6nA at +85°C - preserves accuracy in high-impedance sample-and-hold and battery-monitoring nodes |
| Analog Signal Range | Rail-to-rail (GND to V+) - accommodates full-supply-swing signals without clipping or distortion |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V LOW, +2.4V HIGH) - eliminates need for external logic translators with microcontroller GPIOs |
Pinout & Package
MAX4614ESD is housed in a 14-pin narrow SO (SOIC-N) package with standard 1.27mm pitch, compatible with automated assembly and IPC-7351B footprint SN14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - connect to signal path only when corresponding INx is HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common bidirectional analog ports - serve as input/output junctions for each SPST switch |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive internal gate logic to close respective NO switches |
| 7 | GND | Ground reference - return path for logic and analog substrate; must be low-impedance for leakage control |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; absolute max 6V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog voltages from GND to V+ without clamping or distortion - critical for ±2.5V and unipolar sensor interfaces |
| Guaranteed on-resistance flatness | ≤1Ω variation over full signal range - maintains consistent gain and linearity in precision measurement paths |
| Low charge injection (6.5pC) | Minimizes voltage glitch on sampled nodes - essential for accurate hold-phase stability in SAR ADC front-ends |
| High off-isolation (–85dB) | Prevents signal coupling between inactive channels - preserves channel separation in multi-source A/V routing |
| Industrial temperature grade | –40°C to +85°C operation - qualified for automotive infotainment, industrial PLC I/O, and outdoor equipment |

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 |
|---|---|---|---|
| MAX4614EUD | Same electrical specs, but in 14-pin TSSOP package (3.0mm × 4.4mm vs. SOIC-N 3.9mm × 8.7mm) | Preferred for space-constrained PCBs; requires different land pattern and reflow profile | Select MAX4614EUD when board area is limited and thermal dissipation <500mW suffices |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V dual or +5V single), –40°C to +125°C rating | Suitable for higher-precision industrial sensors requiring extended temperature range and lower RON drift | Choose ADG1414BRUZ when operating beyond +85°C or needing <2Ω RON consistency over temperature |
Compared with MAX4614ESD, MAX4614EUD offers identical functionality in a smaller footprint but reduced power dissipation margin (500mW vs. 640mW), while ADG1414BRUZ trades speed (15ns tON) and cost for superior on-resistance stability and extended temperature capability.

FAQ
What is the maximum supply voltage for MAX4614ESD?
The absolute maximum supply voltage for MAX4614ESD is +6V. However, the recommended operating range is +2V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. At +5.5V, the device maintains full specification compliance including 10Ω max on-resistance and <6nA off-leakage at +85°C. Always observe proper power-supply sequencing-apply V+ before analog or logic signals.
Does MAX4614ESD support bidirectional analog signal flow?
Yes, MAX4614ESD supports fully bidirectional analog signal flow on all COMx–NOx paths. Each SPST switch operates symmetrically: voltage or current can pass from COM to NO or NO to COM with identical on-resistance, capacitance, and leakage characteristics. This is confirmed by the datasheet's "Analog Signal Range" specification (0V to V+) and pin function definitions labeling COMx and NOx as bidirectional terminals.
What is the logic threshold behavior of MAX4614ESD at 3.3V supply?
At +3.3V supply, MAX4614ESD retains TTL/CMOS-compatible logic thresholds: VIN_L = 0.8V (max) and VIN_H = 2.0V (min), per Electrical Characteristics table for +3.3V operation. This ensures reliable interfacing with 3.3V microcontrollers without level shifters. Input current remains ultra-low (<10nA), minimizing loading on driving GPIOs.
Can MAX4614ESD be used in sample-and-hold circuits?
Yes, MAX4614ESD is explicitly listed in the datasheet Applications section for sample-and-hold circuits. Its low charge injection (6.5pC), <6nA off-leakage at +85°C, and ≤1Ω on-resistance flatness over signal range minimize hold-mode droop and acquisition error. Combined with 12ns tON, it enables fast, accurate sampling in multichannel data loggers and test equipment.
Is MAX4614ESD pin-compatible with the 74HC4066?
Yes, MAX4614ESD is pin-compatible with the industry-standard 74HC4066 and MAX4610, as stated in the General Description. Pin mapping (V+, IN1–IN4, COM1–COM4, NO1–NO4, GND) matches exactly across all three devices in the same 14-pin SO package. However, MAX4614ESD improves on 74HC4066 with lower on-resistance (10Ω vs. ~50Ω), faster switching (12ns vs. ~40ns), and guaranteed channel matching (≤1Ω).
