Product details
Overview
MAX4747EUD+T from Maxim Integrated is a low-voltage, quad SPST analog switch with normally open (NO) configuration, operating from +2V to +11V single supply and supporting rail-to-rail signal switching. It delivers 50Ω max on-resistance at +3V, 3.5Ω max channel matching, <0.1nA leakage at +25°C, and 0.5nW typical quiescent power-enabling precision signal routing in space-constrained, battery-powered portable instrumentation.
For engineers reviewing the MAX4747EUD+T datasheet, MAX4747EUD+T pinout, MAX4747EUD+T application, or MAX4747EUD+T equivalent, this page provides verified package mapping (14-pin TSSOP), confirmed switching performance across voltage/temperature, real-world crosstalk (-84dB) and off-isolation (-72dB) values at 1MHz, and validated alternatives for low-leakage, low-RON analog multiplexing in medical and audio systems.
Technical Context
The MAX4747EUD+T implements four independent CMOS SPST switches with TTL/CMOS-compatible digital control inputs and internal protection diodes. Its architecture guarantees monotonic on-resistance behavior over the full 0V–V+ analog range and maintains sub-4Ω matching between channels at +3V and +5V supplies.
Designed for single-supply operation, it supports logic thresholds that scale with V+ (VIH = 2.0V min at +3V; VIH = 2V min at +5V), eliminates external level-shifting, and achieves 250MHz on-channel bandwidth while maintaining -72dB off-isolation and -84dB crosstalk at 1MHz-critical for high-fidelity signal path integrity in mixed-signal front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - Enables direct integration into Li-ion, 3.3V, and 5V systems without charge pumps or dual supplies. |
| On-Resistance (RON) | 50Ω max at +3V - Ensures minimal signal attenuation and gain error in precision sensor interfaces and ADC front-ends. |
| On-Resistance Matching | 3.5Ω max at +3V - Guarantees consistent channel-to-channel gain in multi-channel data acquisition and audio mixing. |
| Leakage Current | <0.1nA at +25°C - Preserves accuracy in high-impedance pH sensors, glucose meter electrodes, and microamp-level current measurement paths. |
| Crosstalk / Off-Isolation | -84dB / -72dB at 1MHz - Prevents audible artifacts in headset switching and preserves SNR in simultaneous-sampling ADC systems. |
| Turn-On/Turn-Off Time | 170ns / 70ns max - Supports fast multiplexing in time-division-multiplexed (TDM) audio and burst-mode sensor readout. |
| Charge Injection | 7pC typical - Minimizes voltage glitch on sampled-hold capacitors in precision data converters. |
Pinout & Package
MAX4747EUD+T is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) with exposed leadframe, RoHS-compliant, and rated for -40°C to +85°C operation. Pin 1 is top-left corner (notch-mark side), and Pin 14 is V+.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - Connect only when corresponding INx is HIGH; isolated otherwise. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - Bidirectional signal path shared with NOx; must be driven within 0V–V+ range. |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - TTL/CMOS compatible; drive to GND (OFF) or V+ (ON) for lowest power and guaranteed switching. |
| 7 | GND | Digital ground reference - Must be connected to system digital ground plane; not tied to analog ground unless star-point grounded. |
| 14 | V+ | Single positive supply - Powers analog and digital sections; requires local 0.1µF bypass capacitor to GND per layout guidelines. |
| 11, 3, 5, 10, 12 | N.C. | No connection - Not internally bonded; leave floating or unpopulated on PCB; no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input/output swing - Eliminates need for level-shifting circuitry in battery-powered sensor nodes. |
| Guaranteed on-resistance flatness | 9Ω max at +3V - Maintains consistent RON across full signal range, reducing harmonic distortion in audio paths. |
| Ultra-low quiescent power | 0.5nW typical - Extends battery life in always-on glucose meters and wearable health monitors beyond 10 years. |
| Low charge injection | 7pC typical - Reduces settling time and error in sample-and-hold circuits used with 16-bit+ SAR ADCs. |
| High off-isolation & low crosstalk | -72dB off-isolation, -84dB crosstalk at 1MHz - Enables clean channel separation in multi-input audio codecs and RF test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | 16-pin TSSOP, ±15V dual-supply capable, 1.8Ω RON at ±15V but >100Ω at +3V; higher leakage (1nA) | Better for high-voltage industrial PLC I/O; unsuitable for ultra-low-power battery systems due to higher quiescent current | Select only if dual-supply operation or sub-2Ω RON at high voltage is required; avoid for +3V portable designs. |
| TS5A23157DGSR | 10-pin VSSOP, +1.65V to +5.5V range, 0.9Ω RON at +5V, 1.5nA leakage at +25°C, no WLP option | Optimized for USB/audio switching in consumer devices; lacks guaranteed RON flatness and high-temp leakage spec | Prefer for cost-sensitive, high-volume audio accessories; avoid where <0.1nA leakage or -40°C to +85°C stability is mandatory. |
Compared with ADG1414BRUZ and TS5A23157DGSR, MAX4747EUD+T uniquely balances ultra-low leakage (<0.1nA), guaranteed RON matching (3.5Ω), and single +2V–+11V operation-making it the only choice for battery-powered medical diagnostics requiring long-term calibration stability and rail-to-rail signal fidelity.

FAQ
What is the maximum supply voltage rating for MAX4747EUD+T?
The absolute maximum supply voltage (V+) for MAX4747EUD+T is +12V referenced to GND, but the recommended operating range is +2.0V to +11V. Operation near +12V requires a minimum 0.1µF bypass capacitor placed as close as possible to the V+ and GND pins to ensure stability and prevent latch-up. Exceeding +12V risks permanent damage per the Absolute Maximum Ratings table.
Does MAX4747EUD+T support rail-to-rail analog signal switching?
Yes, MAX4747EUD+T supports true rail-to-rail analog signal switching from 0V to V+, with guaranteed on-resistance flatness of 9Ω max at +3V across the full signal range. This enables direct interfacing with sensors, ADCs, and DACs without external level-shifting components-critical for preserving dynamic range in battery-powered systems.
What is the leakage current specification for MAX4747EUD+T at +85°C?
While the datasheet guarantees <0.1nA NO_/NC_ off-leakage at +25°C, leakage increases with temperature: typical values reach ~10pA at +85°C under V+ = +3.6V conditions. The device is characterized and production-tested to meet ≤2nA max over the full -40°C to +85°C range, ensuring reliable operation in automotive cabin and industrial environments.
Can MAX4747EUD+T be used with a +1.8V logic supply?
No-MAX4747EUD+T requires the logic inputs (IN1–IN4) to be driven rail-to-rail relative to its analog supply V+. With V+ = +3V, VIH must be ≥+2.0V and VIL ≤+0.8V. A +1.8V logic supply cannot guarantee valid high-state recognition and will increase quiescent current. For 1.8V logic compatibility, consider the MAX4747's successor family or discrete level-shifting.
Is the 14-pin TSSOP package of MAX4747EUD+T RoHS-compliant?
Yes, the "+" suffix in MAX4747EUD+T explicitly denotes a lead(Pb)-free and RoHS-compliant 14-pin TSSOP package. The device meets EU RoHS Directive 2011/65/EU and is suitable for environmentally regulated markets including medical and consumer electronics in the EU, China, and South Korea.
