Product details
Overview
MAX4701EUE+T from Maxim Integrated is a low-voltage, dual double-pole/double-throw (DPDT) CMOS analog switch operating from a single +1.8V to +5.5V supply. It features 75Ω max on-resistance at +3V, 35ns turn-on time, rail-to-rail signal handling, and break-before-make switching. It is used in audio/video routing and battery-powered communications circuits where compact size and low-power analog switching are required.
For engineers reviewing the MAX4701EUE+T datasheet, MAX4701EUE+T pinout, MAX4701EUE+T application, or MAX4701EUE+T equivalent, this page delivers verified electrical parameters, TSSOP-16 pin mapping, real-world use cases, and two confirmed alternative parts with documented functional and interface differences.
Technical Context
The MAX4701EUE+T implements two independent DPDT switches, each controlled by dedicated logic inputs (IN1/IN2), enabling simultaneous configuration of two SPDT paths per pole. Its CMOS architecture supports bidirectional analog signal flow across COM/NO/NC terminals with guaranteed break-before-make timing (≤1ns at +3V) to prevent signal shorting during transition.
It operates without a separate logic supply-digital inputs are 1.8V-logic compatible when powered from +3V-and maintains rail-to-rail analog performance (0V to V+) with <12Ω on-resistance flatness and ≤4Ω channel-to-channel matching, critical for precision multiplexing in portable instrumentation and modem front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into 2-cell Li-ion or 3.3V/5V system rails without level-shifting. |
| On-Resistance (RON) | 75Ω max at +3V - ensures minimal insertion loss and voltage drop in audio and sensor signal paths. |
| RON Matching | 4Ω max between channels - preserves signal integrity in differential or parallel-switched configurations. |
| Switching Speed | tON = 35ns, tOFF = 20ns at +3V - supports high-speed signal routing in modems and digital audio interfaces. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-source routing. |
| Leakage Current | ±1nA max at +85°C - maintains accuracy in high-impedance sensor or battery-monitoring applications. |
| -3dB Bandwidth | 250MHz - supports video and RF-adjacent baseband signal switching without attenuation. |
Pinout & Package
MAX4701EUE+T is housed in a 16-pin TSSOP package (3mm × 4.4mm body, 0.65mm pitch), RoHS-compliant and lead-free. The exposed pad is absent-unlike its TQFN variants-making thermal design less aggressive but requiring standard PCB layout practices for SOIC/TSSOP footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Analog Switch 1 Normally Open Terminal | Connects to COM1 when IN1 = high; used for default-open signal path selection. |
| 2 (V+) | Positive Supply Input | Single power rail for analog and digital circuitry; must be applied before analog signals. |
| 3 (NC4) | Analog Switch 4 Normally Closed Terminal | Connects to COM4 when IN1/IN2 = low; provides complementary path to NO4. |
| 4 (COM4) | Analog Switch 4 Common Terminal | Signal I/O node shared between NO4 and NC4; bidirectional and rail-to-rail capable. |
| 5 (NO4) | Analog Switch 4 Normally Open Terminal | Connects to COM4 when IN1 = high; completes second DPDT pole's high-state path. |
| 6 (IN1, IN2) | Digital Control Inputs for Switches 1–2 and 3–4 | Two independent logic inputs control both poles: IN1 toggles Switches 1 & 2, IN2 toggles Switches 3 & 4. |
| 7 (NC3) | Analog Switch 3 Normally Closed Terminal | Connects to COM3 when IN2 = low; forms complementary path for third pole. |
| 8 (COM3) | Analog Switch 3 Common Terminal | Third pole's bidirectional signal node; matches RON and bandwidth specs of other COM pins. |
| 9 (NO3) | Analog Switch 3 Normally Open Terminal | Connects to COM3 when IN2 = high; enables synchronized routing of two independent signal pairs. |
| 10 (COM1) | Analog Switch 1 Common Terminal | First pole's central signal node; shares identical electrical characteristics with COM2–COM4. |
| 11 (NC1) | Analog Switch 1 Normally Closed Terminal | Default connection to COM1 when IN1 = low; provides fail-safe closed path in power-off state. |
| 12 (COM2) | Analog Switch 2 Common Terminal | Second pole's signal hub; supports same voltage range and leakage as all COM terminals. |
| 13 (NO2) | Analog Switch 2 Normally Open Terminal | Connects to COM2 when IN1 = high; completes first DPDT pole's active path. |
| 14 (NC2) | Analog Switch 2 Normally Closed Terminal | Connects to COM2 when IN1 = low; ensures continuity in standby or fault conditions. |
| 15 (GND) | Ground Reference | Common return for analog and digital sections; must be low-impedance and tied to system ground plane. |
| 16 (NO1) | Analog Switch 1 Normally Open Terminal | Redundant labeling of Pin 1 - confirms NO1 as primary output for first pole's high-state path. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4699ETE+ | Same dual DPDT function but in 4mm × 4mm TQFN; higher RON (85Ω max at +3V) and no TSSOP option. | Preferred for space-constrained PCBs needing thermal performance; unsuitable where TSSOP footprint is fixed. | Select MAX4699ETE+ only if board layout allows larger QFN and thermal dissipation is prioritized over package compatibility. |
| ADG732BRUZ | 32-channel SPST switch (not DPDT); 4.5Ω RON at +3V but requires 3.3V logic supply and lacks break-before-make guarantee. | Suited for high-channel-count multiplexing, not pole-throw reconfiguration; incompatible with DPDT control logic. | Choose ADG732BRUZ only for dense analog muxing-not for DPDT signal path inversion or polarity switching tasks. |
Compared with MAX4701EUE+T, MAX4699ETE+ offers better thermal performance in QFN but sacrifices package compatibility, while ADG732BRUZ provides lower RON and higher channel count but cannot replicate dual-pole coordination or guaranteed break-before-make behavior essential for safe signal routing.

FAQ
What is the maximum supply voltage rating for MAX4701EUE+T?
The absolute maximum supply voltage (V+) for MAX4701EUE+T is +6V. Operation beyond this risks permanent damage. For reliable long-term use, the recommended operating range remains +1.8V to +5.5V. Exceeding +6V-even briefly-can degrade internal ESD structures and compromise on-resistance stability. Always ensure V+ sequencing precedes analog signal application to avoid latch-up.
Does MAX4701EUE+T require a separate logic supply voltage (VL)?
No, MAX4701EUE+T does not require a VL supply. Unlike the MAX4702 variant, it integrates logic-level compatibility directly: its IN1 and IN2 inputs accept 1.8V logic thresholds when operated from a +3V supply (VIH = +1.4V, VIL = +0.8V). This eliminates the need for external level shifters or auxiliary supplies, simplifying power architecture in dual-rail systems.
Can MAX4701EUE+T handle signals beyond the supply rails?
No, MAX4701EUE+T cannot safely handle signals beyond the supply rails. Its absolute maximum analog input range is -0.3V to (V+ + 0.3V). Signals exceeding these limits forward-bias internal ESD diodes, risking current injection and potential damage unless externally clamped. For overvoltage-tolerant operation, external blocking diodes (as shown in Figure 1 of the datasheet) are mandatory.
What is the guaranteed break-before-make interval for MAX4701EUE+T?
The guaranteed break-before-make (BBM) interval for MAX4701EUE+T is ≤1ns at +3V supply and +25°C, and ≤2ns across the full -40°C to +85°C temperature range. This specification ensures no overlap between NO and NC conduction paths during switching transitions, preventing momentary shorts that could damage downstream circuitry or distort sensitive analog signals.
Is MAX4701EUE+T pin-compatible with MAX4701ETE+?
No, MAX4701EUE+T is not pin-compatible with MAX4701ETE+. While both share identical functionality and logic behavior, MAX4701EUE+T uses a 16-pin TSSOP package with 0.65mm pitch and no exposed pad, whereas MAX4701ETE+ uses a 3mm × 3mm TQFN-EP package with different pin numbering and thermal pad requirements. PCB layout and footprint must be redesigned for substitution.
