Product details
Overview
MAX4750EBE+T from Maxim Integrated is a dual single-pole/double-throw (SPDT) analog switch IC operating from a single +2V to +11V supply, delivering rail-to-rail signal handling with 50Ω (max) on-resistance at +3V, 3.5Ω (max) channel matching, and <0.1nA leakage current at +25°C-enabling precision signal routing in battery-powered glucose meters and portable audio systems.
For engineers reviewing the MAX4750EBE+T datasheet, MAX4750EBE+T pinout, MAX4750EBE+T application, or MAX4750EBE+T equivalent, this page provides verified package mapping (16-bump WLP), confirmed SPDT topology, measured dynamic performance (tON = 170ns max at +3V), and two validated alternative parts for low-voltage analog switching designs.
Technical Context
The MAX4750EBE+T implements CMOS-based dual SPDT switching 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 +2V to +11V supply range.
It features guaranteed on-resistance flatness (9Ω max at +3V) and low charge injection (7pC typ), enabling high-fidelity analog signal routing without distortion or settling error in data-acquisition front-ends and audio path selection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - supports direct integration into Li-ion, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 50Ω (max) at +3V - ensures minimal signal attenuation and gain error in sensor interface paths. |
| On-Resistance Matching | 3.5Ω (max) between channels at +3V - enables matched gain/attenuation in differential or dual-path routing. |
| Leakage Current | <0.1nA at TA = +25°C - preserves accuracy in high-impedance medical sensor nodes and pH meter inputs. |
| Off-Isolation | −72dB at 1MHz - suppresses crosstalk between active and inactive signal paths in multi-channel AFEs. |
| Turn-On Time | 170ns (max) at +3V - meets timing requirements for fast-switching multiplexed data acquisition at ≥1 MSPS. |
| Package | 16-bump WLP (2mm × 2mm) - reduces PCB area by >60% vs. TSSOP, critical for space-constrained wearables. |
Pinout & Package
MAX4750EBE+T is housed in a 16-bump wafer-level package (WLP) measuring 2mm × 2mm with bumps on the bottom side. The package is RoHS-compliant and tape-and-reel supplied (T suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1, C4 | NO1, NO2 | Normally open analog terminals - connect to signal sources only when corresponding INx is HIGH. |
| A1, D4 | COM1, COM2 | Common analog ports - serve as bidirectional I/O nodes shared between NO/NC paths. |
| C1, B4 | IN1, IN2 | Digital control inputs - TTL/CMOS-compatible; drive HIGH to close NO path, LOW to close NC path. |
| C3 | GND | Digital ground reference - must be connected to system digital ground plane for logic integrity. |
| B2 | V+ | Single positive supply - powers analog and digital sections; requires local 0.1µF bypass capacitor. |
| A2, A4, D1, D3 | N.C. | No internal connection - left floating; no PCB trace or pad required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - essential for full-scale sensor output capture. |
| Break-before-make timing | 1ns typical - eliminates momentary short-circuit risk during SPDT state transitions in precision signal chains. |
| Low quiescent power | 0.5nW typical - extends battery life in always-on portable diagnostics and handheld test equipment. |
| Guaranteed on-resistance flatness | 9Ω max over full signal range at +3V - maintains consistent gain/attenuation across input voltage swing. |
| −84dB crosstalk at 1MHz | Prevents interference between adjacent switched channels in multi-signal routing applications like audio mixers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4750ETE+ | Same die, 16-pin TQFN-EP (4mm × 4mm) package - larger footprint, exposed pad requires thermal tie to V+. | Suitable for prototyping or higher-power layouts where WLP reflow is not available. | Select when board assembly process lacks WLP capability or thermal dissipation >589mW is needed. |
| ADG732BRUZ | 32-channel SPST, 4.5Ω RON at +3V, but no SPDT topology - requires external routing for dual-path selection. | Used in high-channel-count instrumentation; lacks integrated break-before-make for SPDT operation. | Choose only if system requires >2 switched paths and can accommodate discrete SPDT implementation. |
Compared with MAX4750ETE+, the MAX4750EBE+T saves >70% PCB area and simplifies layout with bump-level interconnect; versus ADG732BRUZ, it delivers true dual SPDT functionality with guaranteed break-before-make timing and lower component count per signal path.

FAQ
What is the maximum supply voltage rating for MAX4750EBE+T?
The MAX4750EBE+T has an absolute maximum supply voltage (V+) of +12V referenced to GND, but its specified operational range is +2V to +11V. Operating continuously at +11V requires a minimum 0.1µF bypass capacitor placed as close as possible to the V+ pin to ensure stability and prevent latch-up. Exceeding +12V risks permanent damage.
Does MAX4750EBE+T support rail-to-rail analog signal switching?
Yes, the MAX4750EBE+T supports rail-to-rail analog signal switching - signals from GND to V+ pass through the switch with minimal distortion or on-resistance variation. This is confirmed by the "Analog Signal Range" specification (0 to V+) and on-resistance flatness data (9Ω max over full range at +3V), making it suitable for full-scale sensor and audio applications.
What is the function of the N.C. bumps on MAX4750EBE+T?
The N.C. bumps (A2, A4, D1, D3) on the MAX4750EBE+T are not internally connected and must remain unconnected on the PCB. They serve no electrical function and should not be soldered or tied to any net. Leaving them floating avoids unintended parasitic coupling and ensures compliance with the device's validated WLP layout guidelines.
Can MAX4750EBE+T be used with a +11V supply while maintaining TTL logic compatibility?
No - TTL logic compatibility (VIH = +2.0V, VIL = +0.8V) is guaranteed only at +3V supply. At +11V, logic inputs must be driven rail-to-rail (0V to +11V) to ensure proper switching and minimize power consumption. Driving IN1/IN2 to +2.0V at +11V may result in undefined states or increased leakage; always reference VIH/VIL to the actual V+ level per the datasheet's logic threshold vs. supply voltage curve.
How does the 16-bump WLP package of MAX4750EBE+T affect thermal performance?
The MAX4750EBE+T's 16-bump WLP has a thermal derating factor of 7.3mW/°C above +70°C and a maximum continuous power dissipation of 589mW at TA = +70°C. Unlike QFN packages, it lacks an exposed pad; heat transfers primarily through bumps into the PCB. For sustained >100µA load currents, ensure adequate copper area and thermal vias beneath the WLP footprint per Application Note 1891.
