Product details
Overview
MAX4702EUE+T from Maxim Integrated is a quad single-pole/double-throw (SPDT) analog switch IC designed for low-voltage signal routing in battery-powered and space-constrained systems. It operates from a single +1.8V to +5.5V supply, delivers 75Ω max on-resistance at +3V, features 35ns turn-on time, rail-to-rail signal handling, and supports 1.0V logic threshold with dedicated VL pin - enabling use in ultra-low-voltage digital control interfaces such as portable audio codecs and sensor multiplexers.
For engineers reviewing the MAX4702EUE+T datasheet, MAX4702EUE+T pinout, MAX4702EUE+T application, or MAX4702EUE+T equivalent, key selection criteria include guaranteed break-before-make timing, channel-to-channel on-resistance matching ≤4Ω, off-isolation of –76dB at 1MHz, and compatibility with 16-pin TSSOP layout constraints for high-density PCBs.
Technical Context
The MAX4702EUE+T implements four independent SPDT switches controlled by a single digital input (IN), with separate VL logic supply pin enabling 1.0V VIH threshold - distinct from the MAX4699/MAX4701 dual DPDT variants. Its CMOS architecture ensures bidirectional analog signal flow, rail-to-rail voltage handling (0V to V+), and break-before-make switching verified to <1ns at +3V.
It requires strict power sequencing: V+ must be applied before VL and analog signals; VL must be ≥1.5V and powered after V+. The device exhibits monotonic on-resistance vs. COM voltage across all supply voltages (+1.8V to +5.5V), with flatness ≤12Ω and leakage ≤1nA at +85°C - critical for precision instrumentation front-ends.
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 gain error in audio and sensor paths. |
| RON Matching | ≤4Ω max between channels - preserves amplitude balance in differential or multi-channel routing applications. |
| Turn-On/Off Time | tON = 35ns, tOFF = 20ns at +3V - supports fast multiplexing in data acquisition and video switching up to ~10 MSPS. |
| Off-Isolation | –76dB at 1MHz - suppresses crosstalk between active and inactive channels in mixed-signal routing. |
| Logic Threshold (VIH) | 1.0V min with VL = +1.5V - allows direct interfacing with 1.2V/1.8V FPGA I/O or low-power microcontroller GPIOs. |
| Leakage Current | ±1nA max at +85°C - maintains signal integrity in high-impedance sensor front-ends and battery-monitoring circuits. |
Pinout & Package
MAX4702EUE+T is housed in a 16-pin TSSOP package (3mm × 4.4mm body, 0.65mm pitch) with exposed pad not present - distinct from TQFN variants. Pin 1 is NO1; pin 16 is COM1. All analog terminals (COM/NO/NC) are bidirectional; IN controls all four SPDT switches simultaneously; VL sets logic threshold independently of V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7, 11 (NO1–NO4) | Normally Open terminal per SPDT switch | Connects to COM when IN = high; open-circuit otherwise - used for default-open signal paths. |
| 4, 6, 8, 12 (COM1–COM4) | Common terminal per SPDT switch | Signal input/output node shared between NO and NC - bidirectional, rail-to-rail capable. |
| 5, 9, 13, 15 (NC1–NC4) | Normally Closed terminal per SPDT switch | Connects to COM when IN = low; open-circuit otherwise - provides fail-safe closed path during logic low. |
| 2 (IN) | Digital control input | Single logic line enabling/disabling all four SPDT switches synchronously - simplifies GPIO usage. |
| 10 (VL) | Logic supply input | Sets VIH/VIL thresholds; must be ≥1.5V and powered after V+ - enables 1.0V-compatible control without level shifters. |
| 14 (V+) | Analog/switching supply | Primary power for analog path; defines signal range (0V to V+) and RON performance. |
| 6 (GND) | Ground reference | Common return for V+, VL, and analog signals - must be low-impedance for leakage and noise control. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPDT with single IN control | Reduces GPIO count and routing complexity versus discrete switch arrays - ideal for compact mux designs. |
| 1.0V logic-compatible VIH (with VL = +1.5V) | Eliminates need for external level translators when interfacing with sub-1.8V logic domains like modern SoCs. |
| Rail-to-rail analog signal handling | Supports full-scale signals from GND to V+ without clipping - essential for audio line drivers and ADC front-ends. |
| Guaranteed break-before-make | Prevents momentary shorting between NO and NC paths - protects sensitive sources and loads during switching. |
| –79dB crosstalk at 1MHz | Minimizes interference between adjacent channels in multi-signal routing - critical for high-fidelity audio and RF sampling. |
Applications
| Audio Signal Multiplexing | Portable Sensor Hub Routing |
|---|---|
|

| Battery-Powered Modem Interface | Low-Voltage Video Signal Switching |
|

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 |
|---|---|---|---|
| MAX4702ETE+ | Same die, 3mm × 3mm TQFN-EP package with exposed pad tied to GND - 30% smaller footprint, better thermal dissipation. | Preferred for space-constrained PCBs where thermal management is critical; requires different land pattern and reflow profile. | Select MAX4702ETE+ when board area is limited and GND plane access allows exposed pad connection. |
| ADG714BRUZ | Quad SPDT, +1.8V to +5.5V, but 4.5Ω typical RON at +3V (vs. 75Ω max for MAX4702); no VL pin - VIH fixed at 0.7×V+. | Better RON for precision instrumentation; lacks 1.0V logic compatibility - requires level-shifting for sub-1.8V controllers. | Choose ADG714BRUZ when lowest on-resistance is prioritized over ultra-low-voltage logic interface. |
Compared with MAX4702ETE+ and ADG714BRUZ, the MAX4702EUE+T offers unique trade-offs: TSSOP packaging eases hand-soldering and optical inspection, its VL pin enables true 1.0V logic compatibility unattainable by ADG714BRUZ, and its guaranteed 4Ω RON matching exceeds ADG714BRUZ's typical 0.5Ω spec - making it optimal for balanced multi-channel routing where logic voltage flexibility and channel uniformity are jointly critical.

FAQ
What is the maximum supply voltage rating for MAX4702EUE+T?
The absolute maximum supply voltage (V+) for MAX4702EUE+T is +6V, though operational specification guarantees performance only from +1.8V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. At +5.5V, on-resistance drops to 40Ω max, improving signal fidelity in higher-voltage systems while maintaining compatibility with standard 5V logic domains.
Does MAX4702EUE+T require external pull-up or pull-down resistors on the IN pin?
No, MAX4702EUE+T does not require external pull-up or pull-down resistors on the IN pin. Its digital input has ±1µA leakage current and defined VIH/VIL thresholds (1.0V/0.4V with VL = +1.5V), allowing direct connection to microcontroller GPIOs. However, in noisy environments or floating-control scenarios, a 100kΩ pull-down is recommended to ensure predictable default state (all switches in NC position).
Can MAX4702EUE+T handle negative analog signals?
No, MAX4702EUE+T cannot handle negative analog signals below GND. Its absolute maximum rating for analog pins is –0.3V, and rail-to-rail operation is defined from 0V to V+. For bipolar signal routing, external clamping diodes or level-shifting circuitry is required - but this degrades on-resistance flatness and increases distortion. Use only within 0V to V+ range for specified performance.
How does the VL pin affect logic compatibility in MAX4702EUE+T?
The VL pin in MAX4702EUE+T sets the logic threshold independently: with VL = +1.5V, VIH is guaranteed ≥1.0V and VIL ≤0.4V, enabling reliable operation with 1.2V or 1.8V logic families. If VL is unconnected or tied to V+, thresholds revert to standard ratios (~0.7×V+), losing 1.0V compatibility. VL must be powered after V+ and held ≥1.5V for specified behavior.
Is MAX4702EUE+T pin-compatible with MAX4701EUE+?
No, MAX4702EUE+T is not pin-compatible with MAX4701EUE+. While both use 16-pin TSSOP packages, their pinouts differ significantly: MAX4701EUE+ has dual IN1/IN2 control inputs and no VL pin, whereas MAX4702EUE+ uses single IN and dedicates pin 10 to VL. Swapping them without PCB revision causes misrouting of control and logic supply - verify against respective Pin Description tables before substitution.
