Product details
Overview
The MAX4733EBL-T from Maxim Integrated is a dual SPST analog switch with one normally open (NO) and one normally closed (NC) channel, designed for low-voltage signal routing in space-constrained systems. It operates from a single +2V to +11V supply, delivers ≤50Ω on-resistance at +3V, ≤25Ω at +5V, 0.1nA leakage current, and supports rail-to-rail analog signals - ideal for battery-powered audio/video switching and portable data-acquisition circuits.
For engineers reviewing the MAX4733EBL-T datasheet, MAX4733EBL-T pinout, MAX4733EBL-T application, or MAX4733EBL-T equivalent, this page provides verified electrical specs, UCSP-9 package layout, break-before-make timing (1ns), crosstalk (-108dB), and real-world design context for signal integrity-critical analog multiplexing.
Technical Context
The MAX4733EBL-T integrates two independent CMOS SPST switches in a single die: one NO and one NC, each controlled by separate TTL/CMOS-compatible digital inputs (IN1, IN2). Its architecture guarantees matched on-resistance (≤3.5Ω at +3V) and flatness (≤9Ω), enabling precise signal path consistency across channels.
It features true rail-to-rail analog operation, charge injection of only 7.5pC, and high-frequency performance with 300MHz on-channel bandwidth and -72dB off-isolation at 1MHz - all while consuming just 0.5nW typical quiescent power, making it suitable for always-on sensor interfaces and low-power portable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - enables direct integration into 2.5V, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal signal attenuation in low-voltage audio and sensor paths. |
| On-Resistance Matching | 3.5Ω max at +3V - maintains amplitude balance between dual signal paths in differential or stereo routing. |
| Leakage Current | ±0.1nA at +25°C - preserves accuracy in high-impedance sensor front-ends and battery-monitoring circuits. |
| Break-Before-Make Time | 1ns - prevents momentary shorting during channel switching in critical signal routing applications. |
| Crosstalk | -108dB at 1MHz - isolates adjacent analog channels in multi-source A/V or data-acquisition systems. |
| Off-Isolation | -72dB at 1MHz - suppresses unwanted coupling from inactive to active signal paths. |
Pinout & Package
The MAX4733EBL-T is housed in a 1.52mm × 1.52mm, 9-bump UCSP (Ultra-Chip-Scale Package) with bottom-side solder bumps. This wafer-level package minimizes PCB footprint and parasitic inductance, supporting high-density portable layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | NO1 | Normally open analog terminal for Channel 1 - connects to COM1 only when IN1 = logic high. |
| A2 | COM1 | Common analog node for Channel 1 - bidirectional I/O shared between NO1 and NC1. |
| A3 | GND | Digital ground reference - must be connected to system ground plane for stable logic and analog performance. |
| B1 | IN1 | Digital control input for Channel 1 - TTL/CMOS-compatible; drives NO1/NC1 state. |
| B3 | IN2 | Digital control input for Channel 2 - independent of IN1, enabling asynchronous dual-channel control. |
| C1 | V+ | Positive supply input - accepts 2.0V–11V; requires local 0.1µF bypass capacitor near the bump. |
| C2 | COM2 | Common analog node for Channel 2 - bidirectional I/O shared between NO2 and NC2. |
| C3 | NC2 | Normally closed analog terminal for Channel 2 - disconnects from COM2 only when IN2 = logic high. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full GND-to-V+ voltage swing without distortion - essential for unbuffered sensor and audio signals. |
| Break-before-make switching (MAX4733 only) | Guaranteed 1ns tBBM prevents signal shorting during channel transition - critical for safe multiplexer sequencing. |
| Ultra-low quiescent power | 0.5nW typical consumption - extends battery life in always-on wearable and IoT edge nodes. |
| Low charge injection (7.5pC) | Minimizes voltage glitch at COM terminals during switching - preserves DC accuracy in precision measurement paths. |
| High off-isolation (-72dB) and low crosstalk (-108dB) | Enables clean separation of sensitive analog sources (e.g., microphone + line-in) on shared PCB traces. |
Applications
| Audio Signal Routing | Portable Data Acquisition |
|---|---|

IC Role / Device Role / Timing Role: Ultra-low-power analog gate controlling signal path activation based on measurement trigger. Use Value: 0.5nW quiescent power reduces system sleep-mode current by >10× vs. discrete FET solutions; +2V minimum V+ supports single-cell Li-ion operation. |
Use Scenario: Isolating unused analog interface lines (e.g., RS-232 receive, modem audio paths) in baseband processors to prevent noise coupling. IC Role / Device Role / Timing Role: High-off-isolation analog switch decoupling idle signal paths from active ones in mixed-signal SoC subsystems. Use Value: -72dB off-isolation suppresses RF interference and clock feedthrough; 300MHz bandwidth accommodates fast transient suppression. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4733EUA+ | 8-pin µMAX package (3mm × 3mm); higher thermal resistance; no exposed pad. | Better suited for prototyping and manual assembly; less optimal for high-density or thermally constrained layouts. | Select when board reworkability or through-hole compatibility is prioritized over size and thermal performance. |
| MAX4733ETA+ | 8-pin TDFN-EP package (3mm × 3mm × 0.8mm); includes exposed thermal pad tied to V+. | Superior power dissipation and EMI shielding; requires careful PCB land pattern per JEDEC MO-229. | Choose for production designs needing enhanced thermal stability and lower noise in high-frequency signal chains. |
Compared with MAX4733EUA+ and MAX4733ETA+, the MAX4733EBL-T offers the smallest footprint (1.52mm²) and lowest parasitic capacitance, making it optimal for ultra-compact portable electronics where board area and signal integrity are critical - though its UCSP requires fine-pitch reflow and bump-level inspection.

FAQ
What is the maximum supply voltage rating for the MAX4733EBL-T?
The MAX4733EBL-T has an absolute maximum supply voltage (V+) of +12V, but the recommended operating range is +2.0V to +11V. Operation above +11V risks reliability degradation; a 0.1µF ceramic bypass capacitor must be placed close to the V+ bump when operating near the upper limit.
Does the MAX4733EBL-T support rail-to-rail analog signal switching?
Yes, the MAX4733EBL-T fully supports rail-to-rail analog signals from GND to V+. Its CMOS switch architecture maintains low and flat on-resistance across the entire analog range - confirmed by typical RON vs. VCOM curves in the datasheet for +2.0V, +3.0V, +5.0V, and +10.0V supplies.
What is the break-before-make timing specification for the MAX4733EBL-T?
The MAX4733EBL-T guarantees a break-before-make interval (tBBM) of 1ns maximum at +3V and +5V supplies under standard test conditions (RL = 300Ω, CL = 35pF). This parameter applies exclusively to the MAX4733 variant and prevents momentary shorting between NO1/NC1 or NO2/NC2 paths.
How does the UCSP-9 package of the MAX4733EBL-T affect PCB layout?
The MAX4733EBL-T's 9-bump UCSP (1.52mm × 1.52mm) requires microvia-based PCB routing and stencil-defined solder paste deposition. Bumps are on the bottom side; the package lacks leads, so thermal and electrical connections rely entirely on solder joints - necessitating IPC Class 3 reflow profiles and X-ray inspection for void detection.
Can the MAX4733EBL-T be used with a +1.8V supply?
No - the MAX4733EBL-T is not specified for operation below +2.0V. At +1.8V, logic thresholds (VIH/VIL) and on-resistance become noncompliant; the device may fail to turn on reliably or exhibit increased leakage. For sub-2V systems, consider the MAX4617 or similar low-voltage optimized switches.
