Product details
Overview
MAX4614EUD+T 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 for precision audio routing and battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4614EUD+T datasheet, MAX4614EUD+T pinout, MAX4614EUD+T application, or MAX4614EUD+T 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 industrial temperature operation.
Technical Context
The MAX4614EUD+T implements CMOS transmission-gate architecture with matched P- and N-channel devices per channel, enabling symmetric conduction and low THD (0.034% at 20Hz–20kHz). Its logic inputs feature fixed 0.8V/2.4V thresholds - independent of supply voltage - ensuring robust interface with both TTL and CMOS controllers across 2V–5.5V operation.
Each NO switch supports bidirectional analog signals from GND to V+, with on-resistance flatness ≤1Ω over the full signal range and charge injection of only 6.5pC. 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 - enables direct integration into Li-ion (3.7V), USB-powered (5V), and ultra-low-power (2.5V) systems without level-shifting. |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision instrumentation and sensor multiplexing. |
| On-Resistance Match | ≤1Ω max between channels - critical for matched gain paths in differential or multi-channel sampling circuits. |
| Turn-On / Turn-Off Time | 12ns / 10ns at +25°C - supports high-speed signal switching in video routing and fast data acquisition. |
| Off-Leakage Current | 6nA max at TA = +85°C - preserves accuracy in high-impedance sample-and-hold and battery-monitoring applications. |
| Analog Signal Range | Rail-to-rail (GND to V+) - allows full utilization of ADC input range and eliminates external biasing in single-supply designs. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high at +5V) - guarantees reliable control from microcontrollers and FPGAs without external buffers. |
Pinout & Package
MAX4614EUD+T is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.1mm body, 0.65mm pitch), optimized for space-constrained portable and industrial PCBs.
| 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 with matched RON. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as input/output junctions for each SPST switch; support rail-to-rail voltage swing. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive internal gate logic to activate respective NO switches. |
| 7 | GND | Ground reference - return path for logic and analog sections; must be low-impedance to minimize switching noise coupling. |
| 14 | V+ | Positive supply - powers analog and digital circuitry; must be decoupled with ≥0.1µF ceramic capacitor near the pin. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance flatness | ≤1Ω variation across full 0V to V+ signal range - maintains consistent gain and linearity in audio and sensor signal chains. |
| Channel-to-channel on-resistance match | ≤1Ω max mismatch - enables precise ratio-metric measurements in multi-channel data loggers and medical front-ends. |
| Ultra-low off-leakage current | 6nA max at +85°C - prevents drift in high-impedance sample-and-hold capacitors and battery voltage monitoring nodes. |
| High off-isolation | -85dB at 100kHz - suppresses crosstalk between adjacent switched audio or communication channels. |
| Low charge injection | 6.5pC - minimizes voltage glitch on hold capacitors, reducing settling time and improving ADC effective resolution. |

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 |
|---|---|---|---|
| MAX4615EUD+T | Four normally closed (NC) switches instead of NO; identical RON, timing, leakage, and package. | Suitable where default-closed signal paths are required (e.g., fail-safe sensor monitoring). | Select MAX4615EUD+T only when NC behavior is functionally required - not a drop-in replacement for MAX4614EUD+T. |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V to +16.5V), 16-TSSOP package - not pin-compatible. | Better suited for higher-voltage industrial I/O modules than battery-powered portable gear. | Choose ADG1414BRUZ only when bipolar supply or sub-2Ω RON is mandatory - requires PCB layout change. |
Compared with MAX4615EUD+T (NC variant) and ADG1414BRUZ (higher-voltage, non-pin-compatible), the MAX4614EUD+T uniquely delivers NO functionality with guaranteed 10Ω max RON, 12ns switching, and industrial temp range in a compact 14-TSSOP - making it optimal for space- and power-constrained signal routing where default-open state is essential.

FAQ
What is the maximum supply voltage rating for the MAX4614EUD+T?
The MAX4614EUD+T has an absolute maximum supply voltage (V+) of +6V, but its specified operating range is +2V to +5.5V. Exceeding +6V risks permanent damage. For reliable long-term operation, Analog Devices recommends staying within the 2V–5.5V range - where all electrical characteristics, including on-resistance and leakage, are fully guaranteed across -40°C to +85°C.
Does the MAX4614EUD+T support rail-to-rail analog signal switching?
Yes, the MAX4614EUD+T 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 capability is confirmed in the datasheet's "Analog Signal Range" specification (0V to V+) and validated by typical operating curves showing flat on-resistance across the full range - enabling direct interface with single-supply ADCs and op-amps.
What is the guaranteed on-resistance matching between channels in the MAX4614EUD+T?
The MAX4614EUD+T guarantees on-resistance matching of ≤1Ω maximum between any two channels at +25°C, and ≤1.2Ω across the full -40°C to +85°C temperature range. This parameter (denoted ΔRON) is measured under standardized conditions (V+ = 4.5V, ICOM = 10mA, VNO = VNC = 3V) and is critical for applications requiring matched gain or ratiometric accuracy, such as multi-channel sensor interfaces.
Can the MAX4614EUD+T operate with a +3.3V supply, and what is its on-resistance at that voltage?
Yes, the MAX4614EUD+T is fully specified for +3.3V operation. At V+ = 3V and TA = +25°C, its typical on-resistance is 8Ω with a maximum of 20Ω; over the full -40°C to +85°C range, RON rises to a maximum of 25Ω. This performance is documented in the "Electrical Characteristics-Single +3.3V Supply" table and supports robust operation in modern 3.3V embedded systems.
Is the MAX4614EUD+T pin-compatible with the industry-standard 74HC4066?
Yes, the MAX4614EUD+T is explicitly designed to be pin-compatible with the 74HC4066 and MAX4610 analog switches. Pin functions (COM1–COM4, NO1–NO4, IN1–IN4, V+, GND) and physical layout in the 14-TSSOP package match - allowing direct replacement in existing designs. However, the MAX4614EUD+T offers superior specs: lower on-resistance (10Ω vs. ~60Ω), faster switching (12ns vs. ~40ns), and guaranteed matching/flatness not found in the 74HC4066.
