Product details
Overview
The MAX4544EUA+T 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 at +5V, guarantees break-before-make switching, and features 5pC max charge injection and 2000V ESD protection - enabling reliable use in battery-powered audio/video multiplexing and test equipment front-ends.
For engineers reviewing the MAX4544EUA+T datasheet, MAX4544EUA+T pinout, MAX4544EUA+T application, or MAX4544EUA+T equivalent, key selection criteria include SPDT topology with guaranteed break-before-make timing, SOT23-6 package compatibility, +2.7V to +12V single-supply operation, low leakage (<10nA at +85°C), and TTL/CMOS logic compatibility across supply voltages.
Technical Context
The MAX4544EUA+T implements a monolithic CMOS SPDT switch architecture with independent digital control (IN) selecting between normally open (NO) and normally closed (NC) paths to a common (COM) terminal. Its internal design ensures guaranteed break-before-make operation (tD = 2–10ns), minimizing transient short-circuits during state transitions.
It supports rail-to-rail analog signal switching (0V to V+) with minimal RON variation (6Ω max flatness) and maintains low dynamic distortion via 5pC max charge injection and <90dB off-isolation at 1MHz - critical for sample-and-hold and precision DAC/ADC interface applications.
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 shifters |
| RON (max) | 60Ω at +5V - ensures minimal signal attenuation and gain error in sensor or audio signal paths |
| Charge Injection | 5pC max - reduces voltage glitch in sample-and-hold and switched-capacitor circuits |
| tON/tOFF | 35ns/25ns typical at +5V - supports high-speed multiplexing up to ~10MHz analog bandwidth |
| ESD Protection | 2000V per Method 3015.7 - provides robust handling margin during board assembly and field operation |
| Leakage (max) | 10nA at +85°C - preserves accuracy in high-impedance sensor or medical front-end nodes |
Pinout & Package
SOT23-6 package (3.0mm × 1.7mm × 1.3mm body, 0.95mm pitch), thermally enhanced with exposed pad (EP) connected to V+ per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open switch terminal | Connects to COM only when IN = high; used for active-high signal path selection |
| 2 - COM | Common analog terminal | Bidirectional I/O node - serves as input or output depending on signal flow direction |
| 3 - NC | Normally Closed switch terminal | Connects to COM only when IN = low; complements NO for complementary path routing |
| 4 - GND | Ground reference | Analog and digital ground return; must be low-impedance for leakage and noise control |
| 5 - V+ | Positive supply input | Accepts +2.7V to +12V; powers internal CMOS switch core and logic interface |
| 6 - IN | Digital control input | TTL/CMOS-compatible; drives switch state (NO ↔ COM or NC ↔ COM) with rail-to-rail logic swing |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents momentary shorting between NO and NC paths - essential for safe channel switching in power-sensitive or fault-tolerant designs |
| 6Ω max RON flatness | Ensures consistent gain and linearity across full 0V–V+ analog input range - critical for precision instrumentation |
| 2Ω max RON matching | Enables accurate differential or ratiometric measurements when paired with matched switches or references |
| 5pC max charge injection | Minimizes settling error and droop in sampling circuits - directly improves effective resolution of 12-bit+ data acquisition systems |
| TTL/CMOS logic compatibility | Supports direct interfacing with microcontrollers and FPGAs across all valid supply voltages without external level translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4544EUT-T | Same die, identical electrical specs, SOT23-6 tape-and-reel packaging (vs. cut tape for +T variant) | No functional difference; suited for automated SMT placement with standard reel logistics | Select for high-volume production requiring JEDEC-compliant reels |
| ADG1419BRMZ | Higher RON (8.5Ω typ), wider supply (±15V dual or +12V single), no guaranteed break-before-make | Better for high-voltage industrial signal chains; unsuitable where B-B-M timing is mandatory | Choose only if higher voltage range or lower RON at ±15V is required - not a drop-in replacement |
Compared with MAX4544EUA+T, the MAX4544EUT-T offers identical performance in reel format for volume manufacturing, while the ADG1419BRMZ trades guaranteed break-before-make and low-voltage optimization for broader supply flexibility and lower on-resistance at higher voltages - making it non-interchangeable in battery-powered or timing-critical designs.

FAQ
What is the maximum supply voltage rating for the MAX4544EUA+T?
The MAX4544EUA+T has an absolute maximum supply voltage of +13V, but its specified operational range is +2.7V to +12V. Operating continuously above +12V risks exceeding safe operating area limits and may degrade reliability or cause permanent damage. Always observe the +12V upper limit in normal use, with transient spikes held below +13V per absolute maximum ratings.
Does the MAX4544EUA+T support rail-to-rail analog signal switching?
Yes, the MAX4544EUA+T supports rail-to-rail analog signal switching from 0V to V+. Its CMOS switch architecture allows bidirectional signal flow across the full supply range with minimal RON variation (6Ω max flatness), making it suitable for precision applications like sensor conditioning and DAC output multiplexing where signal headroom is constrained.
Is break-before-make timing guaranteed for the MAX4544EUA+T?
Yes, break-before-make timing is guaranteed for the MAX4544EUA+T, with a specified delay (tD) of 2ns to 10ns at +25°C. This prevents momentary short-circuiting between NO and NC paths during switching transitions - a critical feature for protecting downstream circuitry in audio routing, test equipment, and medical imaging systems.
What is the thermal performance of the MAX4544EUA+T in SOT23-6 package?
The MAX4544EUA+T in SOT23-6 package has a continuous power dissipation of 571mW at +70°C, derating by 7.1mW/°C above that temperature. Its exposed pad (EP) is internally connected to V+ and must be soldered to a copper pour for optimal thermal conduction - enabling reliable operation up to +85°C ambient in compact, sealed enclosures.
Can the MAX4544EUA+T be used with a +3.3V supply?
Yes, the MAX4544EUA+T is fully specified for +3.3V operation (within the +2.7V to +12V range). At +3.3V, typical RON is 125Ω, tON is 80ns, and leakage remains ≤10nA at +85°C. Logic inputs remain TTL/CMOS compatible, accepting 0V–3.3V swings - making it ideal for interfacing with 3.3V microcontrollers in portable instrumentation.
