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 - used in precision audio routing and battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4614ESD+ datasheet, MAX4614ESD+ pinout, MAX4614ESD+ application, or MAX4614ESD+ equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), sub-6nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and -40°C to +85°C industrial temperature operation.
Technical Context
The MAX4614ESD+ implements a CMOS transmission-gate architecture optimized for low-voltage operation (2V to 5.5V), delivering flat on-resistance (<1Ω variation over full signal range) and matched channel resistance (≤1Ω max mismatch). Its digital inputs feature fixed 0.8V/2.4V thresholds, ensuring robust logic recognition without external level-shifting when powered from +5V.
Each NO switch supports bidirectional analog signals from GND to V+, with <6nA maximum off-leakage at +85°C and 6.5pC charge injection - critical for sample-and-hold accuracy and low-distortion audio switching. The device avoids body-diode conduction by eliminating inherent NMOS/PMOS asymmetry in its switch core.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - enables direct integration into 3.3V and 5V systems without regulators. |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision sensor interfaces. |
| On-Resistance Match | ≤1Ω max between channels - preserves amplitude consistency across multiplexed signal paths. |
| Turn-On / Turn-Off Time | 12ns / 10ns - supports >50MHz switching in high-speed data acquisition and video routing. |
| Off-Leakage Current | 6nA at +85°C - maintains integrity of high-impedance sensor nodes and long-hold capacitors. |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS compatibility with standard microcontroller GPIOs. |
| Rail-to-Rail Signal Range | GND to V+ - allows full utilization of ADC input range and eliminates level-shifter requirements. |
Pinout & Package
MAX4614ESD+ is housed in a 14-pin narrow SO (SOIC-N) package, 3.9mm width, with standard JEDEC MS-012AC footprint and gull-wing leads.
| 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 shared I/O node for each SPST switch; must be routed with controlled impedance. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - CMOS/TTL-compatible; drive switches independently; no internal pull-ups/downs. |
| 7 | GND | Analog/digital ground reference - requires low-impedance connection to system ground plane to minimize crosstalk. |
| 14 | V+ | Positive supply - powers analog and digital sections; bypass with 0.1µF ceramic capacitor close to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Signal Handling | Supports analog signals from GND to V+ without clipping - eliminates need for external biasing in single-supply systems. |
| Guaranteed On-Resistance Flatness | ≤1Ω variation over full 0V to V+ signal range - ensures linear gain response in instrumentation amplifier front-ends. |
| Matched Channel Resistance | ≤1Ω max difference between any two NO channels - enables accurate ratiometric measurements in multi-channel ADC muxes. |
| Low Charge Injection | 6.5pC - minimizes voltage glitch on hold capacitors, preserving >12-bit accuracy in sample-and-hold circuits. |
| Industrial Temperature Range | -40°C to +85°C - qualified for deployment in automotive cabin electronics and industrial PLC I/O modules. |

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 (4.4mm × 3.0mm) - 35% smaller footprint, higher thermal resistance (6.3mW/°C derating). | Better suited for space-constrained PCBs where reflow profile accommodates fine-pitch gull-wings. | Select MAX4614EUD+ when board area is critical and thermal load is light; MAX4614ESD+ preferred for legacy SO layouts and easier hand-soldering. |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V to +16.5V), 16-TSSOP package - not pin-compatible. | Targeted at dual-supply industrial automation where bipolar signal handling and lower RON outweigh pinout constraints. | Choose ADG1414BRUZ only when bipolar operation or sub-2Ω RON is mandatory; MAX4614ESD+ remains optimal for single-supply, cost-sensitive, pin-compatible upgrades. |
Compared with MAX4614EUD+, MAX4614ESD+ offers identical performance with broader PCB assembly flexibility; versus ADG1414BRUZ, it trades bipolar capability and ultra-low RON for proven drop-in compatibility with 74HC4066 footprints and lower system BOM cost.

FAQ
What is the maximum supply voltage rating for MAX4614ESD+?
The absolute maximum supply voltage for MAX4614ESD+ is +6V. Operation above +5.5V violates the recommended operating conditions and risks permanent damage. At +5.5V, on-resistance increases slightly (to ~11Ω), and leakage remains within spec - but sustained use at this limit reduces long-term reliability. Always maintain V+ ≤ +5.5V in normal operation.
Does MAX4614ESD+ support bidirectional analog signal flow?
Yes, MAX4614ESD+ supports fully bidirectional analog signal flow on all NO and COM terminals. Each SPST switch operates identically regardless of signal direction - enabling use in both source-to-load and load-to-source configurations without polarity constraints. This is inherent to its CMOS transmission-gate topology.
Can MAX4614ESD+ be used with a +3.3V supply while maintaining TTL logic compatibility?
No - at +3.3V supply, MAX4614ESD+ requires logic-high input ≥2.0V (not 2.4V) and logic-low ≤0.8V per datasheet Section "Electrical Characteristics-Single +3.3V Supply". Standard 3.3V TTL outputs (typically 2.4V min HIGH) still meet this, but 3.3V CMOS drivers with VOH = 3.3V are fully compatible. Verify actual driver VOH/ VOL against the +3.3V threshold table.
What is the thermal resistance (θJA) of the MAX4614ESD+ in its narrow SO package?
The junction-to-ambient thermal resistance (θJA) for MAX4614ESD+ in the 14-pin narrow SO package is 8.00°C/mW, meaning it dissipates 640mW at +70°C ambient before reaching its +85°C maximum junction temperature. Derating is linear above +70°C - reduce power by 8mW per °C rise to ensure safe operation at full industrial temperature range.
Is MAX4614ESD+ pin-compatible with the 74HC4066?
Yes, MAX4614ESD+ is explicitly pin-compatible with the industry-standard 74HC4066, sharing identical pinout, function mapping, and SOIC-14 footprint. However, MAX4614ESD+ improves upon 74HC4066 with lower on-resistance (10Ω vs. ~120Ω), faster switching (12ns vs. ~40ns), and guaranteed matching/flatness - enabling direct replacement without layout changes.
