Product details
Overview
MAX4747ETE+ from Maxim Integrated is a low-voltage, quad SPST analog switch with normally open (NO) configuration, operating from +2V to +11V single supply and handling rail-to-rail signals. 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-ideal for precision signal routing in space-constrained, battery-powered systems like glucose meters and PDAs.
For engineers reviewing the MAX4747ETE+ datasheet, MAX4747ETE+ pinout, MAX4747ETE+ application, or MAX4747ETE+ equivalent, this page provides verified electrical specs, TQFN-EP package details, real-world use scenarios, and validated alternative parts for low-leakage, low-RON analog switching in portable medical and communications circuits.
Technical Context
The MAX4747ETE+ implements four independent CMOS SPST switches with TTL/CMOS-compatible digital inputs and rail-to-rail analog signal capability. Its architecture guarantees monotonic on-resistance over temperature and supply voltage, with break-before-make timing not applicable (as it lacks NC paths).
It features integrated ESD protection and internal clamp diodes, supports single-supply operation down to +2V, and maintains tight on-resistance flatness (9Ω max at +3V) across the full analog range-enabling accurate signal pass-through in data-acquisition front-ends and audio routing without gain error or distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - enables direct interface with Li-ion, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal insertion loss and signal attenuation in low-voltage sensor interfaces. |
| On-Resistance Matching | 3.5Ω max between channels at +3V - critical for matched gain paths in differential or multi-channel acquisition. |
| Leakage Current | <0.1nA at +25°C - preserves accuracy in high-impedance sensor nodes and battery-monitoring circuits. |
| Turn-On/Off Time | 170ns / 70ns max at +3V - supports fast multiplexing in real-time sampling applications up to ~1MHz. |
| Off-Isolation | −72dB at 1MHz - suppresses crosstalk between inactive channels in dense analog routing. |
| Package | 16-pin Thin QFN-EP (4mm × 4mm) with exposed pad tied to V+ - provides low thermal resistance and compact PCB footprint. |
Pinout & Package
MAX4747ETE+ uses a 16-pin Thin QFN-EP package (4mm × 4mm) with exposed thermal pad connected to V+. Pin 15 is V+, Pin 6 is GND, and the device contains four independent NO switch channels with dedicated IN/COM/NO terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | COM1, COM2 | Common analog terminals for Switch 1 and Switch 2 - bidirectional signal path entry/exit points. |
| 2 | NO2 | Normally open terminal of Switch 2 - connects to COM2 only when IN2 is high. |
| 4, 13 | IN2, IN1 | Digital control inputs - TTL/CMOS-compatible; drive high to close corresponding NO switch. |
| 5, 12 | IN3, IN4 | Digital control inputs - enable independent switching of all four channels. |
| 7 | NO3 | Normally open terminal of Switch 3 - closed only when IN3 = high. |
| 9, 10 | COM3, COM4 | Common analog terminals for Switch 3 and Switch 4 - complete the four SPST paths. |
| 11 | NO4 | Normally open terminal of Switch 4 - activated by IN4 high. |
| 16 | NO1 | Normally open terminal of Switch 1 - connects to COM1 when IN1 = high. |
| 15 | V+ | Positive supply for analog and digital circuitry - must be bypassed with ≥0.1µF capacitor near pin. |
| 6 | GND | Digital/analog ground reference - common return for supply and logic. |
| 8, 14 | N.C. | No internal connection - left unconnected on PCB; no routing required. |
| EP | Exposed Pad | Internally connected to V+ - must be soldered to PCB V+ plane for thermal and electrical performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals from GND to V+ pass with ≤9Ω RON flatness - eliminates clipping in ±0.5V–3.3V sensor outputs. |
| Ultra-low leakage | <0.1nA at +25°C - prevents DC offset drift in microamp-level biomedical sensing paths. |
| Low quiescent power | 0.5nW typical - extends battery life in always-on monitoring devices beyond 10 years at 3V. |
| TTL/CMOS logic compatibility | VIH = 2.0V min, VIL = 0.8V max at +3V - allows direct MCU GPIO control without external level shifters. |
| High off-isolation | −72dB at 1MHz - isolates unused channels in multi-signal AFEs to prevent measurement contamination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4747EUD+ | Same die, 14-pin TSSOP package - larger footprint (5mm × 4.4mm), no exposed pad, higher thermal resistance. | Better suited for prototyping or legacy layouts where QFN reflow is unavailable. | Select MAX4747EUD+ if manual soldering or through-hole adapter use is required; avoid for high-density portable designs. |
| ADG1419BRUZ | Quad SPST, 4.5Ω RON max at +5V, −80dB off-isolation, but requires dual ±5V or single +15V supply - not 2V–11V compatible. | Targeted at higher-voltage industrial test equipment, not battery-powered portable systems. | Choose ADG1419BRUZ only when supply exceeds +11V or isolation >−72dB is mandatory; not drop-in for MAX4747ETE+. |
Compared with MAX4747EUD+, the MAX4747ETE+ offers superior thermal performance and 30% smaller PCB area; versus ADG1419BRUZ, it enables true low-voltage operation down to +2V with 10× lower leakage, making it uniquely suitable for sub-3V medical and wearable electronics.

FAQ
What is the maximum supply voltage for MAX4747ETE+?
The absolute maximum supply voltage for MAX4747ETE+ is +12V referenced to GND, but the recommended operational range is +2.0V to +11V. Exceeding +11V risks violating the absolute maximum rating and may degrade reliability. Always bypass V+ with a minimum 0.1µF capacitor placed as close as possible to the MAX4747ETE+ pin to ensure stable operation at high supply voltages.
Does MAX4747ETE+ support rail-to-rail analog signals?
Yes, MAX4747ETE+ fully supports rail-to-rail analog signals-from GND to V+-with guaranteed on-resistance flatness of 9Ω max over the entire range at +3V. This enables accurate pass-through of sensor outputs, audio waveforms, and other signals that swing across the full supply without clipping or distortion, as confirmed in the Typical Operating Characteristics graphs.
What is the function of the exposed pad (EP) on MAX4747ETE+?
The exposed pad (EP) on MAX4747ETE+ is internally connected to V+ and must be soldered to the PCB's V+ copper pour. It serves dual purposes: lowering thermal resistance to improve power dissipation and enhancing electrical stability by reducing inductance in the supply path. Failure to connect EP to V+ may result in elevated junction temperature and degraded switching performance.
Can MAX4747ETE+ be used with a +2.5V supply?
Yes, MAX4747ETE+ is fully specified and functional at +2.5V. Electrical characteristics including RON (60Ω max), leakage (<2nA), and logic thresholds remain valid across the +2.0V to +11V range. At +2.5V, RON increases slightly versus +3V, but the device maintains rail-to-rail signal handling and TTL/CMOS compatibility with adjusted VIH/VIL thresholds per the datasheet curves.
Is MAX4747ETE+ pin-compatible with MAX4747EUD+?
No, MAX4747ETE+ (16-pin TQFN-EP) is not pin-compatible with MAX4747EUD+ (14-pin TSSOP). Their pin counts, layouts, and terminal assignments differ significantly-for example, MAX4747ETE+ places COM1/COM2 on pins 1/3 and NO1 on pin 16, whereas MAX4747EUD+ assigns COM1/COM2 to pins 2/4 and NO1 to pin 1. PCB redesign is required for substitution.
