Product details
Overview
MAX4714ELT+T from Maxim Integrated is a low-on-resistance, single-pole/double-throw (SPDT) analog switch operating from +1.6V to +3.6V supply, delivering 0.8Ω max on-resistance at +3V, 18ns max turn-on time, and guaranteed break-before-make switching-used for precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4714ELT+T datasheet, MAX4714ELT+T pinout, MAX4714ELT+T application, or MAX4714ELT+T equivalent, this page provides verified package mapping (6-pin µDFN), confirmed RON flatness (0.18Ω max), logic compatibility (1.8V CMOS at +3V), and real-world leakage specs (±5nA off-leakage) critical for low-power, high-fidelity analog path design.
Technical Context
The MAX4714ELT+T implements a CMOS-based SPDT switch architecture with rail-to-rail analog signal handling (0V to V+) and bidirectional current capability (±150mA continuous). Its break-before-make timing (tBBM = 1ns max at +3V) prevents momentary shorting during state transitions, essential for power routing and communications circuits.
It features 1.8V CMOS-compatible digital control (VIL = 0.5V, VIH = 1.4V at +3V supply) and ultra-low quiescent current (2µA max), enabling direct interface with modern low-voltage microcontrollers without level-shifting. Charge injection is tightly controlled at 22pC typical, minimizing transient errors in sampling systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.8Ω max at +3V supply - enables <10mV drop at 100mA, preserving signal integrity in low-voltage sensor interfaces. |
| RON Matching | 0.18Ω max difference between NO and NC paths - ensures balanced channel performance in differential or dual-path routing. |
| Turn-On/Off Time | tON = 18ns max, tOFF = 12ns max - supports >20MHz switching in high-speed data multiplexing applications. |
| Supply Range | +1.6V to +3.6V single supply - compatible with Li-ion, coin-cell, and regulated 1.8V/3.3V rails without auxiliary supplies. |
| Off-Leakage Current | ±5nA max (NO/NC to COM) - maintains accuracy in high-impedance measurement nodes (e.g., pH sensors, thermopiles). |
| Logic Compatibility | 1.8V CMOS input thresholds at +3V supply - interoperable with standard I/O of ARM Cortex-M, MSP430, and similar MCUs. |
| Package | 6-pin µDFN (1.5mm × 1.0mm × 0.8mm) - supports high-density PCB layouts in space-constrained portable devices. |
Pinout & Package
MAX4714ELT+T is housed in a 6-pin µDFN package (1.5mm × 1.0mm, 0.8mm height) with wettable flanks, optimized for automated optical inspection and thermal performance in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | Inverts logic sense: high = connect COM to NO, low = connect COM to NC; accepts rail-to-rail input up to +3.6V. |
| 2 - V+ | Positive supply input | Single supply rail (+1.6V to +3.6V); powers analog and digital sections; decoupling capacitor required near pin. |
| 3 - GND | Ground reference | Analog and digital common return; must be low-impedance connection to minimize noise coupling into signal paths. |
| 4 - NC | Normally closed analog terminal | Connects to COM when IN = low; bidirectional; rated for ±150mA continuous, ±300mA pulsed current. |
| 5 - COM | Common analog terminal | Central signal node; connects to either NC or NO depending on IN state; supports full rail-to-rail analog swing (0V to V+). |
| 6 - NO | Normally open analog terminal | Connects to COM when IN = high; matches NC in RON, flatness, and leakage; shares same voltage/current ratings. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | 1ns max delay prevents overlap conduction - eliminates signal shorting during switching in power routing or battery backup paths. |
| Low RON flatness | 0.18Ω max variation over full analog range (0V to V+) - ensures consistent gain and minimal THD (<0.01%) in audio routing. |
| Ultra-low off-leakage | ±5nA max at TA = −40°C to +85°C - preserves DC accuracy in high-impedance sensor front-ends and medical instrumentation. |
| Charge injection control | 22pC typical - reduces settling error in sample-and-hold and ADC input multiplexers, especially with 1nF load capacitance. |
| Small-footprint µDFN | 1.5mm × 1.0mm footprint - saves >60% board area vs. SC70-6 while maintaining thermal resistance (2.1mW/°C derating above +70°C). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4599EXT+T | Same pinout, identical RON (0.8Ω max), but slower tON/tOFF (25ns/18ns max) and no guaranteed break-before-make. | Acceptable where timing margin exists and overlapping conduction is tolerable (e.g., non-critical signal routing). | Select MAX4599EXT+T only if cost sensitivity outweighs need for guaranteed BBM and faster switching. |
| TMUX1574DSGR | Lower RON (0.5Ω typ), wider supply (1.08V–5.5V), but larger 8-pin VSSOP package and higher leakage (±25nA). | Suitable for mixed-voltage systems requiring 1.2V logic compatibility, but less optimal for ultra-low-leakage or space-constrained designs. | Choose TMUX1574DSGR when interfacing with sub-1.8V processors or when extended supply range justifies larger footprint and higher leakage. |
Compared with MAX4599EXT+T and TMUX1574DSGR, the MAX4714ELT+T uniquely balances ultra-fast switching, guaranteed break-before-make, and ultra-low leakage in the smallest possible package-making it optimal for battery-powered precision analog systems where size, speed, and signal fidelity are jointly constrained.

FAQ
What is the maximum continuous current rating for MAX4714ELT+T?
The MAX4714ELT+T supports ±150mA continuous current through its NO, NC, and COM terminals. This rating applies across the full operating temperature range (−40°C to +85°C) and ensures reliable operation in battery-powered signal routing and power path applications without thermal derating under typical PCB conditions.
Does MAX4714ELT+T require external pull-up or pull-down resistors on the IN pin?
No, the MAX4714ELT+T does not require external biasing on the IN pin. Its 1.8V CMOS-compatible input has guaranteed thresholds (VIL ≤ 0.5V, VIH ≥ 1.4V at +3V supply) and low input leakage (±1µA), allowing direct connection to MCU GPIOs or logic gates without additional components.
Can MAX4714ELT+T pass analog signals beyond the supply rails?
No, the MAX4714ELT+T cannot pass analog signals beyond the supply rails. Its specified analog signal range is strictly 0V to V+, with internal clamping diodes limiting voltages on NO, NC, and COM to (V+ + 0.3V) or −0.3V relative to GND. Exceeding these limits risks damage or increased leakage.
Is MAX4714ELT+T pin-compatible with MAX4714EXT+T?
Yes, MAX4714ELT+T and MAX4714EXT+T share identical pinouts and electrical specifications, differing only in package: µDFN-6 (ELT) vs. SC70-6 (EXT). Both use the same die and functional behavior, enabling layout reuse when migrating between packages based on thermal or density requirements.
What is the typical charge injection value for MAX4714ELT+T, and why does it matter?
The MAX4714ELT+T exhibits 22pC typical charge injection, measured with VCOM = 1.5V and CL = 1nF. This parameter directly impacts settling time and offset error in sample-and-hold circuits and multiplexed ADC front-ends-lower values like this reduce post-switching correction overhead and improve effective resolution.
