Product details
Overview
MAX4702ETE+T from Maxim Integrated is a quad single-pole/double-throw (SPDT) analog switch IC designed for low-voltage signal routing in portable and battery-powered systems. It operates from a single +1.8V to +5.5V supply, delivers 75Ω max on-resistance at +3V, supports rail-to-rail analog signals, and features 35ns turn-on time and 1nA max leakage at +85°C - enabling high-fidelity audio/video switching in space-constrained designs.
For engineers reviewing the MAX4702ETE+T datasheet, MAX4702ETE+T pinout, MAX4702ETE+T application, or MAX4702ETE+T equivalent, key selection criteria include guaranteed break-before-make timing, 4Ω max channel-to-channel RON matching, -76dB off-isolation at 1MHz, and 1.0V logic threshold compatibility with 1.5V VL supply - critical for ultra-low-power mixed-signal interface design.
Technical Context
The MAX4702ETE+T implements four independent SPDT switches controlled by a single digital input (IN), with dedicated VL pin enabling 1.0V logic-high threshold when powered from 1.5V. Its CMOS architecture ensures bidirectional signal flow, rail-to-rail voltage handling (0V to V+), and break-before-make switching to prevent signal shorting during state transitions.
It guarantees flat on-resistance (≤12Ω variation over signal range) and tight channel matching (≤4Ω ΔRON) across temperature (-40°C to +85°C), supporting precision analog multiplexing. The 250MHz -3dB bandwidth and -79dB crosstalk at 1MHz confirm suitability for high-fidelity audio and broadband signal routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration with Li-ion, 3.3V, and 5V system rails without level-shifting. |
| On-Resistance (RON) | 75Ω max at +3V supply - ensures minimal signal attenuation and distortion in audio paths and sensor interfaces. |
| RON Matching | 4Ω max between channels - maintains amplitude consistency across multiplexed signals in instrumentation or AFEs. |
| Turn-On/Off Time | tON = 35ns, tOFF = 20ns at +3V - supports fast channel switching in real-time signal conditioning and data acquisition. |
| Off-Isolation | -76dB at 1MHz - suppresses coupling between inactive and active signal paths in multi-channel routing. |
| Logic Threshold (VIH) | 1.0V min with VL = +1.5V - allows direct interfacing with 1.2V/1.5V logic families without external translators. |
| Leakage Current | ±1nA max at +85°C - preserves signal integrity in high-impedance sensor front-ends and battery-monitoring circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4702EUE+ | Same electrical specs but in 16-pin TSSOP package (5mm × 4.4mm vs. 3mm × 3mm) | Preferred where hand-soldering, prototyping, or legacy footprint compatibility is required | Select for ease of assembly or when board space permits larger package |
| ADG1414BRUZ | Quad SPDT with 1.5Ω RON at +5V but requires ≥2.7V logic supply; no VL pin; 16-TSSOP only | Better RON for high-current analog paths but lacks 1.0V logic compatibility and QFN option | Choose when ultra-low on-resistance is critical and 1.5V logic interface is unnecessary |
Compared with MAX4702ETE+T, MAX4702EUE+ offers identical functionality in a larger, more manufacturable package, while ADG1414BRUZ trades 1.0V logic compatibility and compact QFN for lower RON - making MAX4702ETE+T optimal for space-constrained, ultra-low-voltage portable designs.

FAQ
What is the logic supply requirement for MAX4702ETE+T?
The MAX4702ETE+T requires two supplies: V+ (analog power, +1.8V to +5.5V) and VL (logic power, +1.5V). VL sets the 1.0V logic-high threshold and must be powered after V+ to ensure proper initialization. Applying VL before V+ may cause undefined switching behavior or increased leakage in MAX4702ETE+T.
Does MAX4702ETE+T support rail-to-rail analog signals?
Yes, MAX4702ETE+T supports rail-to-rail analog signal handling from 0V to V+. Its CMOS switch architecture allows signals equal to the supply rails to pass with minimal distortion or on-resistance variation - confirmed by typical RON flatness ≤12Ω across the full 0V–V+ range at +3V supply in the MAX4702ETE+T datasheet.
What is the maximum operating temperature for MAX4702ETE+T?
The MAX4702ETE+T is rated for continuous operation from -40°C to +85°C ambient temperature. All key parameters - including 75Ω max RON, ±1nA leakage, and 35ns tON - are guaranteed across this full industrial temperature range, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables for MAX4702ETE+T.
How does the break-before-make timing work in MAX4702ETE+T?
MAX4702ETE+T guarantees break-before-make (BBM) switching with tBBM ≥ 1ns at +3V supply. This means the "off" path disconnects before the "on" path closes, preventing momentary shorting between NO and NC terminals. BBM is inherent to the internal control logic and requires no external timing circuitry in MAX4702ETE+T designs.
Can MAX4702ETE+T be used with a 1.2V logic controller?
MAX4702ETE+T supports 1.0V logic-high threshold when VL = +1.5V, making it compatible with 1.2V controllers if the controller's VOH exceeds 1.0V and VOL stays below 0.4V. However, margin is reduced versus 1.5V logic; verify actual VIH/VIL levels under load, as MAX4702ETE+T does not guarantee operation below 1.0V VIH.
