Product details
Overview
MAX4544CSA+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, 5pC max charge injection, guaranteed break-before-make switching, and supports TTL/CMOS logic inputs - ideal for audio/video switching and battery-powered instrumentation.
For engineers reviewing the MAX4544CSA+T datasheet, MAX4544CSA+T pinout, MAX4544CSA+T application, or MAX4544CSA+T equivalent, key selection criteria include SPDT topology with NC/NO paths, SOT23-6 package constraints, ±10mA continuous current rating, 2000V ESD protection, and compatibility with +3.3V/+5V DAC/ADC interface circuits.
Technical Context
The MAX4544CSA+T implements a CMOS transmission-gate architecture with rail-to-rail analog signal handling (0V to V+) and bidirectional channel operation. Its control logic accepts TTL/CMOS-compatible inputs and guarantees break-before-make timing (2ns–10ns delay) to prevent signal shorting during state transitions.
It features internal ESD protection (>2000V per Method 3015.7), low leakage (10nA max at +85°C), and stable on-resistance flatness (6Ω max) across the full analog voltage range - enabling accurate signal integrity in sample-and-hold and sensor multiplexing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.7V to +12V single supply - enables direct interfacing with 3.3V and 5V logic and analog rails without level shifters. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and gain error in precision analog paths. |
| Charge Injection | 5pC max - reduces voltage glitch and settling error in sample-and-hold and ADC front-end circuits. |
| Break-Before-Make Delay | 2ns to 10ns - prevents momentary shorting between NC and NO paths during switching, critical for fault-tolerant routing. |
| Leakage Current | 10nA max at +85°C - maintains high impedance isolation in high-impedance sensor or bias networks over temperature. |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and end-equipment integration. |
| Switching Speed | tON = 35ns, tOFF = 25ns at +5V - supports medium-speed signal routing in communications and test equipment. |
Pinout & Package
SOT23-6 package: 2.9mm × 2.8mm footprint, 0.95mm pitch, exposed pad (not electrically connected in this variant), surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open terminal | Connects to COM when IN = high; used as active signal path in default-open configuration. |
| 2 (COM) | Common analog terminal | Bidirectional signal port - serves as input or output depending on system topology and switch state. |
| 3 (NC) | Normally Closed terminal | Connects to COM when IN = low; provides fail-safe or default-closed routing path. |
| 4 (GND) | Ground reference | Analog and digital ground return; must be low-impedance for optimal leakage and noise performance. |
| 5 (V+) | Positive supply input | Single power rail for analog and logic sections; supports up to +12V with absolute max rating of +13V. |
| 6 (IN) | Digital control input | TTL/CMOS-compatible; drives internal gate logic - high = connect COM to NO, low = connect COM to NC. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents signal shorting during transition - essential for protecting downstream circuitry in multiplexer and relay-replacement designs. |
| 6Ω max RON flatness | Maintains consistent gain and linearity across full analog input range (0V to V+), critical for precision measurement systems. |
| 2Ω max RON matching | Enables matched channel performance in differential or dual-path architectures without external trimming. |
| 5pC max charge injection | Minimizes voltage step errors in sampling circuits - directly improves effective resolution in 12-bit+ data acquisition systems. |
| TTL/CMOS logic compatibility | Accepts standard logic thresholds across full supply range - eliminates need for external level-shifting in mixed-voltage systems. |

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 SPDT function and SOT23-6 package, but rated for -40°C to +85°C industrial temperature range vs. 0°C to +70°C for MAX4544CSA+T. | Required for extended-temperature deployments (e.g., automotive cabin modules, outdoor test gear). | Select MAX4544EUT-T when operating beyond commercial temperature limits; otherwise MAX4544CSA+T suffices for office/lab environments. |
| ADG1419BRMZ | SPDT switch in 10-lead MSOP; 4.7Ω typical RON, 12V max supply, but no guaranteed break-before-make and higher 12pC charge injection. | Suitable for low-RON priority designs where timing control is managed externally or not required. | Choose ADG1419BRMZ only if lower on-resistance outweighs need for intrinsic break-before-make safety; verify external timing control. |
Compared with MAX4544CSA+T, MAX4544EUT-T extends thermal capability without altering electrical behavior, while ADG1419BRMZ trades guaranteed switching sequence for lower RON - making MAX4544CSA+T optimal for cost-sensitive, temperature-stable SPDT routing where intrinsic safety and precision are prioritized.

FAQ
What is the maximum supply voltage rating for the MAX4544CSA+T?
The MAX4544CSA+T has an absolute maximum supply voltage (V+) of +13V, though its specified operational range is +2.7V to +12V. Exceeding +13V risks permanent damage. The device is characterized and guaranteed across its full +2.7V to +12V range for parameters including on-resistance, leakage, and switching speed - ensuring reliable performance in both 3.3V and 5V systems as well as higher-voltage industrial rails.
Does the MAX4544CSA+T support rail-to-rail analog signal switching?
Yes, the MAX4544CSA+T supports rail-to-rail analog signal switching: its analog terminals (COM, NO, NC) operate from GND to V+, with guaranteed performance across the full range. This allows seamless interfacing with ADCs, DACs, op-amps, and sensors without external level-shifting. The on-resistance flatness remains within 6Ω over this span, preserving signal linearity and minimizing distortion in precision applications like medical ultrasound and portable instrumentation.
Is break-before-make timing guaranteed for the MAX4544CSA+T?
Yes, break-before-make timing is guaranteed for the MAX4544CSA+T, with a specified delay (tD) of 2ns to 10ns at +25°C (RL = 300Ω, CL = 35pF). This intrinsic feature prevents momentary shorting between NC and NO paths during switching - a critical safety mechanism in applications such as relay replacement, multiplexer-based sensor readout, and transmit/receive path selection where signal integrity and downstream component protection are essential.
What is the leakage current specification for the MAX4544CSA+T at elevated temperature?
The MAX4544CSA+T specifies a maximum COM off-leakage current (ICOM(OFF)) of 10nA at +85°C, measured with VCOM = 4.5V and VNO/VNC = 1V or 4.5V. This low, temperature-stable leakage ensures minimal error in high-impedance circuits - such as thermocouple amplifiers, pH sensor interfaces, and precision voltage references - where even sub-nanoampere currents can induce significant offset or drift.
Can the MAX4544CSA+T be used with a +3.3V supply?
Yes, the MAX4544CSA+T is fully functional with a +3.3V supply. Electrical characteristics are specified down to +2.7V, including 125Ω max on-resistance (typical 75Ω), 80ns–400ns switching times, and 10nA max leakage at +85°C. Logic inputs remain TTL/CMOS-compatible, accepting 0V–3.3V swings. Its low 5µW quiescent power consumption further enhances suitability for +3.3V battery-powered systems like handheld test equipment and portable medical devices.
