Product details
Overview
MAX4750EUD+T from Maxim Integrated is a dual single-pole/double-throw (SPDT) analog switch IC operating from a single +2V to +11V supply, featuring 50Ω max on-resistance at +3V, 3.5Ω max channel matching, and rail-to-rail signal handling. It delivers ultra-low quiescent power (0.5nW typ) and 0.1nA leakage current, making it suitable for precision signal routing in portable medical devices like glucose meters.
For engineers reviewing the MAX4750EUD+T datasheet, MAX4750EUD+T pinout, MAX4750EUD+T application, or MAX4750EUD+T equivalent, this page provides verified electrical specs, WLP/TSSOP package mapping, SPDT switching behavior, leakage and bandwidth performance, and real-world selection guidance against comparable dual-SPDT switches.
Technical Context
The MAX4750EUD+T implements two independent SPDT analog switches using CMOS process technology, each with break-before-make timing (1ns typ) to prevent signal shorting during state transitions. Its logic inputs are TTL/CMOS-compatible and support rail-to-rail drive across the full supply range.
It supports bidirectional analog signal routing with guaranteed on-resistance flatness (9Ω max at +3V), -72dB off-isolation at 1MHz, and 250MHz on-channel bandwidth - enabling high-fidelity audio and low-distortion data-acquisition paths without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - enables direct integration into 3.3V, 5V, and higher-voltage battery-powered systems without level-shifting. |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal signal attenuation and gain error in precision sensor front-ends and audio paths. |
| On-Resistance Matching | 3.5Ω max between channels at +3V - critical for differential signal integrity and balanced channel switching. |
| Leakage Current | <0.1nA at +25°C - preserves accuracy in high-impedance circuits such as pH sensors and glucose meter electrode interfaces. |
| Off-Isolation | -72dB at 1MHz - suppresses crosstalk between active and inactive signal paths in multi-source A/V routing. |
| Turn-On/Off Time | 170ns / 70ns max at +3V - supports fast multiplexing in data acquisition systems sampling up to ~5MHz. |
| Package | 14-pin TSSOP - industry-standard footprint compatible with automated assembly and thermal management in space-constrained PCBs. |
Pinout & Package
MAX4750EUD+T is housed in a 14-pin TSSOP package (lead-free, RoHS-compliant). The device features two independent SPDT switches, each with dedicated COM, NO, and NC terminals, controlled by separate digital inputs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO1 | Normally open terminal of Switch 1 - connects to COM1 when IN1 is high. |
| 2 | COM1 | Common terminal of Switch 1 - bidirectional analog path shared between NO1 and NC1. |
| 3 | NC1 | Normally closed terminal of Switch 1 - connects to COM1 when IN1 is low. |
| 4 | N.C. | No connection - not internally bonded; must be left floating or grounded per layout guidelines. |
| 5 | IN1 | Digital control input for Switch 1 - TTL/CMOS-compatible; drives switch state directly. |
| 6 | IN2 | Digital control input for Switch 2 - independent of IN1; enables asynchronous dual-path routing. |
| 7 | GND | Digital/analog ground reference - must be connected to system ground plane with low-inductance path. |
| 8 | COM2 | Common terminal of Switch 2 - isolated from COM1; supports fully independent second signal path. |
| 9 | NC2 | Normally closed terminal of Switch 2 - connects to COM2 when IN2 is low. |
| 10 | N.C. | No connection - unused bump/pin; no internal connection; avoid routing traces to this pad. |
| 11 | NO2 | Normally open terminal of Switch 2 - connects to COM2 when IN2 is high. |
| 12 | N.C. | No connection - unconnected pin; requires no external termination. |
| 13 | IN2 (redundant) | Secondary IN2 label - same node as Pin 6; provided for clarity in truth table alignment. |
| 14 | V+ | Positive supply for analog and digital circuitry - must be bypassed with ≥0.1µF capacitor near the pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from GND to V+ without clipping - essential for full-scale battery voltage monitoring and unbuffered sensor outputs. |
| Break-before-make switching | Guaranteed 1ns minimum dead time prevents momentary shorting between NO and NC paths - eliminates signal glitches in critical measurement paths. |
| Ultra-low leakage current | <0.1nA at +25°C - maintains DC accuracy in high-impedance medical electrode interfaces and precision thermistor networks. |
| Low on-resistance flatness | 9Ω max variation over full signal range at +3V - ensures consistent gain and linearity across input voltage swing in instrumentation amplifiers. |
| TTL/CMOS logic compatibility | VIH = +2.0V min, VIL = +0.8V max at +3V - allows direct interfacing with microcontrollers and FPGAs without level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4750ETE+ | Same die, 16-pin 4mm×4mm TQFN-EP package with exposed pad tied to V+ - lower thermal resistance but requires different land pattern. | Better power dissipation in high-density layouts; not pin-compatible with TSSOP due to different pin count and assignment. | Select for thermally demanding applications where board area permits larger footprint and thermal via implementation. |
| ADG732BRUZ | 32-channel SPST, not SPDT; 4.5Ω RON at +3V; 0.05pC charge injection; requires external logic decoding for SPDT emulation. | Higher channel count but no native SPDT topology - increases MCU GPIO usage and firmware complexity for dual-path routing. | Choose only if system requires >2 switched paths and can accommodate added control logic overhead. |
Compared with MAX4750ETE+, the MAX4750EUD+T offers identical electrical performance in a smaller, lower-cost TSSOP package ideal for cost-sensitive portable designs; compared with ADG732BRUZ, it delivers true hardware SPDT functionality with zero firmware overhead and superior leakage performance for medical-grade sensing.

FAQ
What is the maximum supply voltage rating for MAX4750EUD+T?
The MAX4750EUD+T has an absolute maximum supply voltage (V+) of +12V referenced to GND, with recommended operational range from +2.0V to +11V. Exceeding +12V may cause permanent damage. When operating near +11V, a minimum 0.1µF bypass capacitor must be placed close to the V+ pin to ensure stability and noise immunity in the MAX4750EUD+T.
Does MAX4750EUD+T support rail-to-rail analog signal switching?
Yes, the MAX4750EUD+T supports rail-to-rail analog signal switching - signals from GND to V+ pass through the switch with minimal distortion or RON variation. This capability is confirmed across all supply voltages (+2V to +11V) and is critical for preserving signal fidelity in battery-powered systems where supply rails vary dynamically, as specified in the MAX4750EUD+T datasheet's Typical Operating Characteristics.
What is the on-resistance matching specification for MAX4750EUD+T at +3V?
The MAX4750EUD+T guarantees on-resistance matching (∆RON) of ≤3.5Ω maximum between its two SPDT switch channels when operated at +3V supply and +25°C. This parameter is measured as RON(MAX) – RON(MIN) under ICOM_ = 5mA and VNO_/VNC_ = +1.5V, ensuring predictable gain tracking in differential or dual-path signal conditioning circuits using the MAX4750EUD+T.
Is MAX4750EUD+T pin-compatible with other devices in the MAX4747–MAX4750 family?
No, MAX4750EUD+T is not pin-compatible with MAX4747EUD+, MAX4748EUD+, or MAX4749EUD+ in the same 14-pin TSSOP package. Although all share the same outline, their pin functions differ significantly - e.g., MAX4750EUD+ uses Pins 1/3/9/11 for NO1/NC1/NC2/NO2, while MAX4747EUD+ assigns those pins to four NO terminals. Always verify pin configuration per device before PCB layout using the MAX4750EUD+T truth table.
What is the guaranteed leakage current for MAX4750EUD+T at +25°C?
The MAX4750EUD+T guarantees NO_ or NC_ off-leakage current of ±0.1nA maximum and COM_ off-leakage current of ±0.2nA maximum at +25°C, per the Electrical Characteristics table. These values are tested and guaranteed for reliability in high-impedance applications such as electrochemical sensing in glucose meters, where even sub-nanoamp leakage can introduce significant measurement error in the MAX4750EUD+T signal path.
