Product details
Overview
MAX4614CUD+ 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 MAX4614CUD+ datasheet, MAX4614CUD+ pinout, MAX4614CUD+ application, or MAX4614CUD+ equivalent, this page delivers verified electrical specs, TSSOP-14 pin mapping, real-world use cases, and two validated alternative parts for low-voltage analog switching designs.
Technical Context
The MAX4614CUD+ implements CMOS-based SPST switching with TTL/CMOS-compatible digital inputs (0.8V/2.4V thresholds), operates from a single +2V to +5.5V supply, and guarantees matched on-resistance (≤1Ω) and flatness (≤1Ω) across all four NO channels over the full analog signal range.
It supports bidirectional analog signals up to V+, features <6nA off-leakage at +85°C, and delivers 70MHz on-channel bandwidth with -96dB crosstalk and -85dB off-isolation at 100kHz - enabling precision signal routing without distortion or coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - enables direct integration into 2.5V, 3.3V, and 5V logic/system rails without level shifting. |
| On-Resistance (max) | 10Ω at +5V - ensures minimal voltage drop and signal attenuation in low-level sensor or audio paths. |
| On-Resistance Match | ≤1Ω between channels - critical for matched gain/attenuation in multi-channel instrumentation or balanced signal paths. |
| Turn-On / Turn-Off Time | 12ns / 10ns - supports high-speed multiplexing in sampling systems and fast-switching communication interfaces. |
| Off-Leakage Current | 6nA at +85°C - preserves accuracy in high-impedance sample-and-hold or battery-monitoring circuits. |
| Analog Signal Range | 0V to V+ - allows rail-to-rail input/output operation, simplifying interface with ADCs, DACs, and op-amps. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high at +5V) - ensures reliable control from microcontrollers and FPGAs without external buffers. |
Pinout & Package
MAX4614CUD+ is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.1mm), optimized for space-constrained portable and industrial PCB layouts.
| 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 shared I/O nodes for each SPST switch; must be routed to signal source/load. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - active-HIGH logic; drive directly from 3.3V/5V GPIO with no pull-up required. |
| 7 | GND | Analog/digital ground reference - requires low-impedance connection to system ground plane to minimize noise coupling. |
| 14 | V+ | Positive supply pin - must be decoupled with ≥0.1µF ceramic capacitor close to pin to stabilize switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates need for external biasing in single-supply data-acquisition front-ends. |
| Guaranteed on-resistance flatness | ≤1Ω variation over full signal range - maintains consistent gain/attenuation in precision measurement applications. |
| Low charge injection (6.5pC) | Minimizes voltage glitch at COM node during switching - critical for sample-and-hold and switched-capacitor circuits. |
| High off-isolation (-85dB) | Prevents signal bleed-through between inactive channels - essential for clean channel separation in A/V routing. |
| Pin compatibility with 74HC4066/MAX4610 | Enables drop-in replacement in legacy designs without layout changes - reduces redesign risk and qualification time. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615CUD+ | Four normally closed (NC) switches instead of NO - complementary logic behavior (ON when INx = LOW). | Suitable where default-closed safety path is required (e.g., fail-safe sensor disconnect). | Select MAX4615CUD+ only if NC functionality matches system fault-state requirements; not pin/functionally interchangeable with MAX4614CUD+. |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply range (+3V to +40V), but lower leakage (1pA typ at +25°C). | Better suited for high-voltage industrial I/O modules, less optimal for ultra-low-power battery operation. | Choose ADG1414BRUZ when operating above +5.5V or requiring sub-pA leakage; MAX4614CUD+ remains preferred for <5.5V, <10Ω RON, and fast timing. |
Compared with MAX4615CUD+, the MAX4614CUD+ provides normally open behavior ideal for signal gating; compared with ADG1414BRUZ, it offers lower RON and faster switching at the cost of narrower supply range - making it optimal for portable, low-voltage, high-fidelity analog routing.

FAQ
What is the maximum supply voltage for MAX4614CUD+?
The absolute maximum supply voltage for MAX4614CUD+ is +6V, but the recommended operating range is +2V to +5.5V. Exceeding +5.5V risks permanent damage and violates the guaranteed specifications - always maintain V+ within this window for reliable on-resistance, leakage, and timing performance in production designs using MAX4614CUD+.
Does MAX4614CUD+ support bidirectional analog signals?
Yes, MAX4614CUD+ supports fully bidirectional analog signal flow between NO and COM terminals. Each of its four SPST switches passes signals equally well in either direction, enabling flexible routing in both source-to-load and load-to-source configurations - a key capability confirmed in the datasheet's pin description and absolute maximum ratings for NO_, COM_, and NC_ pins in MAX4614CUD+.
What is the on-resistance temperature coefficient of MAX4614CUD+?
MAX4614CUD+ exhibits an on-resistance increase of approximately 0.2Ω/°C above +25°C, derived from the 13Ω max RON specification at TMIN to TMAX (+70°C) versus 10Ω max at +25°C. This linear drift impacts precision gain matching in wide-temperature industrial applications - designers should account for it in calibration routines for systems using MAX4614CUD+.
Can MAX4614CUD+ operate from a +3.3V supply?
Yes, MAX4614CUD+ is fully specified for +3.3V operation: on-resistance is guaranteed ≤20Ω max, tON/tOFF remain ≤15ns/12ns, and logic thresholds (0.8V low / 2.0V high) ensure compatibility with standard 3.3V CMOS outputs - making MAX4614CUD+ a robust choice for mixed-voltage systems where +3.3V is the primary rail.
Is MAX4614CUD+ pin-compatible with the 74HC4066?
Yes, MAX4614CUD+ is explicitly pin-compatible with the industry-standard 74HC4066, sharing identical pinout, function assignment, and footprint in the 14-pin TSSOP package - enabling direct substitution without PCB modification, while delivering superior performance including lower on-resistance, faster switching, and tighter channel matching than MAX4614CUD+.
