Product details
Overview
MAX4614EUD 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 battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4614EUD datasheet, MAX4614EUD pinout, MAX4614EUD application, or MAX4614EUD equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), sub-10nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and -40°C to +85°C extended temperature operation.
Technical Context
The MAX4614EUD implements CMOS transmission-gate architecture with matched P- and N-channel MOSFETs per channel, enabling symmetric conduction and rail-to-rail analog signal swing. Its logic inputs meet TTL thresholds (0.8V low / 2.4V high) under +5V supply, ensuring direct interface with microcontroller GPIOs without level shifting.
Each NO switch exhibits flat on-resistance (≤1Ω variation over 0V to V+ signal range) and tight channel-to-channel matching (≤1Ω max ΔRON), critical for precision multiplexing in instrumentation and sample-and-hold circuits where gain/offset errors must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports single-supply operation in Li-ion (3.3V/3.7V) and USB-powered systems. |
| On-Resistance (max) | 10Ω at +5V - ensures ≤0.1% gain error in 1kΩ sensor interfaces; 20Ω at +3V enables 3.3V MCU system compatibility. |
| On-Resistance Match | ≤1Ω max between channels - eliminates inter-channel crosstalk-induced measurement offset in multi-sensor ADC front-ends. |
| Turn-On/Turn-Off Time | 12ns / 10ns at +5V - supports >30MHz digital signal switching and fast multiplexed sampling in real-time control loops. |
| Off-Leakage Current | 6nA max at +85°C - preserves charge integrity in high-impedance sample-and-hold capacitors (>1μF hold time). |
| Analog Signal Range | 0V to V+ - enables full-rail signal routing without clipping in single-supply op-amp and ADC signal chains. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - allows direct connection to legacy 5V MCUs and modern 3.3V FPGAs without external translators. |
Pinout & Package
MAX4614EUD is housed in a 14-pin TSSOP package (JEDEC MO-153, 5mm × 4.4mm, 0.65mm pitch), optimized for space-constrained portable designs and offering thermal performance up to 500mW at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - conduct only when corresponding INx = HIGH; bidirectional signal path with matched RON. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - connect to signal source/load; support rail-to-rail voltage swing (0V to V+). |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - accept TTL/CMOS logic levels; no pull-up/down required; drive capability sufficient for direct MCU GPIO interfacing. |
| 7 | GND | Analog/digital ground reference - shared return path; requires low-impedance PCB connection to minimize switching noise coupling. |
| 14 | V+ | Positive supply input - powers internal CMOS switches and logic; must be applied before analog signals to prevent latch-up. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports 0V to V+ analog signals without distortion - eliminates need for level-shifting circuitry in single-supply sensor interfaces. |
| Guaranteed on-resistance flatness | ≤1Ω variation across full signal range - maintains consistent gain/attenuation in precision gain-switching applications. |
| Low charge injection (6.5pC) | Minimizes voltage glitch on sampled capacitors - critical for <12-bit accuracy in switched-capacitor ADC drivers. |
| High off-isolation (-85dB @ 100kHz) | Reduces crosstalk between active and inactive channels - essential for clean multi-channel audio routing and communication signal separation. |
| Extended temperature grade (-40°C to +85°C) | Validated operation across industrial ambient range - suitable for automotive body electronics and outdoor IoT sensor nodes. |

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 |
|---|---|---|---|
| MAX4614CUD | Same electrical specs but 0°C to +70°C temperature range; identical pinout and package (14 TSSOP). | Not rated for industrial environments with cold start or high-ambient conditions. | Select MAX4614CUD only for commercial-grade consumer devices operating within 0°C–70°C ambient. |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), lower leakage (0.5nA typ at +85°C), same 14-TSSOP footprint but different pin mapping (IN/COM/NO order differs). | Superior leakage performance but requires PCB layout revision due to non-pin-compatible pinout. | Choose ADG1414BRUZ when ultra-low leakage dominates design priority and board redesign is acceptable. |
Compared with MAX4614CUD, the MAX4614EUD adds extended temperature qualification without sacrificing speed or matching; versus ADG1414BRUZ, it trades slightly higher leakage for guaranteed pin compatibility and tighter on-resistance flatness - making MAX4614EUD optimal for drop-in upgrades in existing 74HC4066-replacement layouts requiring industrial temp range.

FAQ
What is the maximum supply voltage rating for MAX4614EUD?
The MAX4614EUD 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 operating area limits and may cause irreversible damage. The device is commonly used at +3.3V and +5V supplies in portable and industrial systems, with on-resistance degrading predictably below +2.5V.
Does MAX4614EUD support bidirectional analog signal flow?
Yes, the MAX4614EUD supports fully bidirectional analog signal flow on all NO and COM terminals. Each SPST switch functions 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 and rail-to-rail voltage handling.
How does the on-resistance of MAX4614EUD vary with supply voltage?
MAX4614EUD on-resistance increases as supply voltage decreases: 10Ω max at +5V, 20Ω max at +3V, and up to 100Ω max at +2.5V. This behavior is documented in the Electrical Characteristics tables and confirmed by typical curves showing RON vs. VCOM across supply voltages. Designers must account for this in gain-critical paths.
Is MAX4614EUD pin-compatible with the 74HC4066?
Yes, the MAX4614EUD is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4066, sharing identical 14-pin TSSOP pinout, terminal labeling (NO/COM/IN), and logic polarity. It improves upon the 74HC4066 with lower on-resistance, faster switching, tighter matching, and guaranteed rail-to-rail operation - enabling drop-in replacement without PCB changes.
What is the off-isolation performance of MAX4614EUD at 100kHz?
The MAX4614EUD provides -85dB off-isolation at 100kHz, measured as 20log10(VCOM/VNO) with 50Ω source and load impedances. This specification ensures minimal signal coupling from an active channel into an off-state channel, directly supporting clean multi-channel audio routing and high-fidelity communication signal separation in dense PCB layouts.
