Product details
Overview
The MAX4544ESA+ 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, 5pC max charge injection, and guarantees break-before-make switching - enabling reliable channel isolation in audio, test equipment, and portable instrumentation.
For engineers reviewing the MAX4544ESA+ datasheet, MAX4544ESA+ pinout, MAX4544ESA+ application, or MAX4544ESA+ equivalent, key selection criteria include guaranteed break-before-make timing (2ns–10ns), RON flatness ≤6Ω over full signal range, ESD rating >2000V per Method 3015.7, and SOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4544ESA+ implements a CMOS-based SPDT architecture with TTL/CMOS-compatible digital control inputs and bidirectional analog signal paths. Its internal switch structure ensures no DC path between NC and NO terminals during transition, enforced by a dedicated break-before-make timing circuit (tD = 2ns min, 10ns max at +25°C).
It supports rail-to-rail analog signals (0V to V+) and logic inputs across its full supply range (+2.7V to +12V), with leakage currents specified at ≤10nA at +85°C and charge injection tightly controlled to ≤5pC - critical for sample-and-hold and precision DAC/ADC interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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 front-ends and audio paths. |
| RON Flatness | ≤6Ω - maintains consistent channel gain across 0V–5V input range, critical for linearity in data acquisition. |
| Charge Injection | ≤5pC - limits voltage glitch on sampled nodes, preserving accuracy in high-resolution ADC interfaces. |
| tON/tOFF | 35ns/25ns typical at +5V - supports fast multiplexing in real-time signal conditioning and automated test equipment. |
| Break-Before-Make | 2ns–10ns delay - prevents momentary shorting between NC and NO paths, essential for fault-tolerant signal routing. |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling margin during board assembly and field service. |
Pinout & Package
The MAX4544ESA+ is housed in a 6-pin SOT23 package (JEDEC MO-178AA, package code T633-2), with exposed pad connected to V+. Pin 1 is marked by lettering nearest to it on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open terminal | Connects to COM when IN = high; open-circuit when IN = low - defines one SPDT output path. |
| 2 (COM) | Common analog terminal | Bidirectional signal port shared between NO and NC; must remain within 0V to V+ during operation. |
| 3 (NC) | Normally Closed terminal | Connects to COM when IN = low; open-circuit when IN = high - defines second SPDT output path. |
| 4 (GND) | Ground reference | Analog and digital ground return; must be low-impedance and tied directly to system ground plane. |
| 5 (V+) | Positive supply | Single power rail input; absolute max rating is +13V; exposed pad (EP) must be soldered to V+ for thermal performance. |
| 6 (IN) | Digital control input | TTL/CMOS-compatible; drives internal switch logic; high = connect COM to NO, low = connect COM to NC. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents signal shorting during state transitions - eliminates cross-talk risk in safety-critical routing. |
| 6Ω max RON flatness | Maintains amplitude fidelity across full analog input range - avoids distortion in audio and sensor signal chains. |
| 5pC max charge injection | Minimizes sampling errors in precision data converters - supports 16-bit+ resolution without calibration overhead. |
| 2.7V–12V single-supply operation | Eliminates dual-rail design complexity - simplifies power architecture in battery-powered and industrial systems. |
| TTL/CMOS logic compatibility | Accepts standard logic thresholds across supply voltages - removes need for external level shifters. |

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 | SOT23-6 package with same pinout and electrical specs; top mark AAAM; rated -40°C to +85°C (same as ESA+). | No functional difference; identical performance and footprint - differs only in tape-and-reel packaging and ordering suffix. | Select MAX4544EUT-T for automated SMT assembly requiring reel delivery; MAX4544ESA+ is tube-packaged for prototyping or low-volume use. |
| ADG1419BRMZ | 44Ω max RON at +5V but higher 12pC charge injection; requires dual ±15V or single +12V supply; 10-lead MSOP package. | Higher RON matching (0.5Ω) but lacks guaranteed break-before-make; better for high-voltage industrial mux, not portable low-power designs. | Choose ADG1419BRMZ only if lower RON is prioritized over charge injection and break-before-make - not drop-in compatible due to pin count and layout. |
Compared with MAX4544ESA+, MAX4544EUT-T offers identical electrical behavior and mechanical fit with optimized packaging for volume production, while ADG1419BRMZ trades guaranteed break-before-make and ultra-low charge injection for slightly lower RON and higher supply flexibility - requiring PCB redesign and signal integrity reassessment.

FAQ
What is the maximum supply voltage rating for the MAX4544ESA+?
The MAX4544ESA+ has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2.7V to +12V. Exceeding +13V may cause permanent damage. The device is fully specified at +5V and +3.3V supplies, delivering 60Ω max RON and 35ns tON within these ranges. Always apply V+ before analog signals to avoid latch-up.
Does the MAX4544ESA+ support rail-to-rail analog signal switching?
Yes, the MAX4544ESA+ supports rail-to-rail analog signals from 0V to V+ across its full operating supply range. This is enabled by its CMOS switch architecture and internal level-shifting logic. At +5V supply, the analog signal range is 0V to +5V with ≤6Ω RON flatness - ensuring minimal gain variation and distortion in precision applications like sensor interfacing and audio routing.
Is break-before-make timing guaranteed for the MAX4544ESA+?
Yes, break-before-make timing is guaranteed for the MAX4544ESA+, with a specified delay (tD) of 2ns minimum to 10ns maximum at +25°C. This feature prevents momentary shorting between NC and NO terminals during switching transitions - a critical requirement in fault-tolerant signal routing, such as in medical ultrasound beamforming or test equipment channel selection where signal integrity must be preserved.
What is the ESD protection level of the MAX4544ESA+?
The MAX4544ESA+ provides >2000V ESD protection per Method 3015.7 on all pins. This rating applies to human-body-model (HBM)-like testing and ensures robust handling during PCB assembly, rework, and field service. The protection is inherent to the device's internal structure and does not require external components - supporting reliable deployment in manufacturing and end-use environments without added protection circuitry.
Can the MAX4544ESA+ operate from a +3.3V supply?
Yes, the MAX4544ESA+ is fully operational from a +3.3V supply (within its +2.7V to +12V range). At +3.3V, typical RON is 125Ω max, tON is 80ns–400ns, and leakage remains ≤10nA at +85°C. Logic inputs remain TTL/CMOS-compatible, accepting 0V/3.3V thresholds. This makes the MAX4544ESA+ suitable for modern low-voltage embedded systems, including portable diagnostics and IoT sensor hubs.
