Product details
Overview
MAX4544EUT+TC6W from Maxim Integrated is a single-pole/double-throw (SPDT) analog switch IC designed for precision signal routing in low-voltage, single-supply systems. It operates from +2.7V to +12V, delivers 60Ω max on-resistance (RON), 5pC max charge injection, guaranteed break-before-make switching, and supports TTL/CMOS logic inputs. It is used in battery-powered audio/video switching, test equipment signal paths, and +3V/+5V ADC/DAC interface multiplexing.
For engineers reviewing the MAX4544EUT+TC6W datasheet, MAX4544EUT+TC6W pinout, MAX4544EUT+TC6W application, or MAX4544EUT+TC6W equivalent, key selection criteria include SPDT topology with break-before-make timing, SOT23-6 footprint compatibility, RON flatness ≤6Ω, leakage <10nA at +85°C, and ESD robustness >2000V per Method 3015.7.
Technical Context
The MAX4544EUT+TC6W implements a CMOS transmission-gate architecture optimized for bidirectional analog signal switching across its COM–NO and COM–NC paths. Its internal control logic enforces guaranteed break-before-make operation (tD = 2–10ns), preventing momentary short-circuits during state transitions.
It features rail-to-rail analog signal handling (0V to V+), low 100pA typical off-leakage, and minimal 5pC charge injection-critical for sample-and-hold and precision instrumentation front-ends where voltage settling and glitch energy must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Single-pole/double-throw (SPDT) analog switch with break-before-make guarantee |
| Supply Range | +2.7V to +12V single supply - enables direct integration with 3.3V, 5V, and 12V systems without level-shifting |
| RON (max) | 60Ω at +5V - ensures minimal signal attenuation and gain error in sensor/ADC paths |
| RON Flatness | 6Ω max - maintains consistent channel gain across full analog input range (0V to V+) |
| Charge Injection | 5pC max - limits voltage glitch on high-impedance nodes (e.g., integrator inputs, sample capacitors) |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling during board assembly and field service |
| tON/tOFF | 35ns/25ns typ at +5V - supports fast multiplexing in data acquisition and communication systems |
Pinout & Package
SOT23-6 package (6-pin, 1.5mm × 2.3mm body, exposed pad connected to V+ per datasheet). Pin 1 marked with dot; top marking "AAAM".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open terminal | Connects to COM when IN = high; open-circuit otherwise - forms one switched path |
| 2 (COM) | Common analog terminal | Bidirectional I/O node shared between NO and NC paths - must be driven or loaded within 0V to V+ range |
| 3 (NC) | Normally Closed terminal | Connects to COM when IN = low; open-circuit otherwise - forms second switched path |
| 4 (GND) | Ground reference | Analog and digital ground return; must be low-impedance to minimize noise coupling into switch channels |
| 5 (V+) | Positive supply | Single power rail for analog and logic sections; exposed pad (EP) must be soldered to V+ plane for thermal and ESD performance |
| 6 (IN) | Digital control input | TTL/CMOS-compatible logic input; active-high control - drives internal gate bias for both transmission gates |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | Guaranteed 2–10ns delay prevents signal shorting during switching - essential for safe multiplexing of multiple sources |
| RON matching | 2Ω max difference between NO and NC paths - ensures balanced gain and phase response in differential or dual-path designs |
| Low leakage | 10nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring circuits |
| Fast switching | 35ns tON, 25ns tOFF at +5V - enables ≥10MHz multiplexing rates in real-time signal conditioning |
| Charge injection control | 5pC max - minimizes residual offset in precision sampling applications like medical ultrasound front-ends |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4543EKA-T | 8-pin SOT23-8; integrates one NO and one NC SPST switch - requires external wiring to emulate SPDT function | Less compact layout; higher board area; no native break-before-make guarantee across channels | Select when dual independent SPST control is needed instead of monolithic SPDT; verify timing coordination in PCB layout |
| ADG1419BRMZ | 6-pin LFCSP; 4.7Ω RON typ at +5V; 0.2pC charge injection; but only rated to +85°C industrial grade | Superior RON and charge injection, yet lacks guaranteed break-before-make and has lower ESD rating (1500V HBM) | Select for ultra-low distortion audio or high-resolution metrology where RON flatness and charge injection dominate over ESD robustness |
Compared with MAX4544EUT+TC6W, MAX4543EKA-T offers greater channel independence but increases layout complexity and timing uncertainty, while ADG1419BRMZ improves analog fidelity at the cost of reduced system-level ruggedness and missing break-before-make assurance.

FAQ
What is the maximum supply voltage rating for MAX4544EUT+TC6W?
The MAX4544EUT+TC6W has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2.7V to +12V. Exceeding +13V risks permanent damage per the Absolute Maximum Ratings table. Operation at +12V is fully characterized and supported across temperature ranges, delivering optimal RON and switching speed performance.
Does MAX4544EUT+TC6W support rail-to-rail analog signal switching?
Yes, the MAX4544EUT+TC6W supports rail-to-rail analog signal operation from 0V to V+. The datasheet specifies an analog signal range of VCOM, VNO, VNC = 0 to V+, and confirms minimal RON variation across this full range - critical for preserving signal integrity in sensor interfaces and audio paths.
Is break-before-make timing guaranteed for MAX4544EUT+TC6W?
Yes, break-before-make timing is guaranteed for MAX4544EUT+TC6W, with a specified tD (delay) of 2ns to 10ns at +25°C. This feature is explicitly called out in the Features section and verified in Figure 3b of the datasheet, ensuring no overlap between NO and NC conduction states during switching transitions.
What is the thermal pad connection requirement for MAX4544EUT+TC6W?
The SOT23-6 package of MAX4544EUT+TC6W includes an exposed pad (EP) that must be soldered directly to the V+ copper plane on the PCB. Per the datasheet's Package Information section and Figure 1 notes, connecting EP to V+ is required for proper thermal dissipation and ESD protection - floating or grounding the pad degrades both reliability and electrical performance.
Can MAX4544EUT+TC6W operate with a +3.3V supply?
Yes, MAX4544EUT+TC6W is fully specified for +3.3V operation (within the +3.0V to +3.6V range). Electrical Characteristics tables confirm RON = 50–125Ω, tON = 80–400ns, and tOFF = 50–125ns at +3.3V. Logic inputs remain compatible, and analog signal range remains 0V to +3.3V - making it ideal for modern low-voltage embedded systems.
