Product details
Overview
The MAX4544EPA from Maxim Integrated is a single-pole/double-throw (SPDT) precision analog switch operating from a single +2.7V to +12V supply, delivering 60Ω max on-resistance, 6Ω max RON flatness, and guaranteed break-before-make switching. It features 5pC max charge injection, <5µW power consumption, and 2000V ESD protection-ideal for low-power audio/video routing and battery-operated instrumentation.
For engineers reviewing the MAX4544EPA datasheet, MAX4544EPA pinout, MAX4544EPA application, or MAX4544EPA equivalent, key selection criteria include SPDT topology with break-before-make timing, SOT23-6 package compatibility, leakage performance at +85°C (10nA max), and TTL/CMOS logic compatibility across 3.3V/5V/12V supplies.
Technical Context
The MAX4544EPA implements a CMOS transmission-gate architecture with dual-channel control logic enabling true SPDT operation: one common (COM), one normally open (NO), and one normally closed (NC) terminal per switch. Its break-before-make timing (2ns min, 10ns max at +25°C) prevents signal shorting during state transitions.
It supports rail-to-rail analog signals from GND to V+, maintains low RON flatness (≤6Ω) over the full voltage range, and guarantees <100pA off-leakage at +25°C-critical for high-impedance sensor multiplexing and precision sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.7V to +12V single supply - enables direct interface with 3.3V, 5V, and 12V systems without level shifting |
| RON (max) | 60Ω at +5V - ensures minimal signal attenuation in audio and DAC/ADC signal paths |
| RON Flatness (max) | 6Ω - preserves linearity across full analog input range (0V to V+), critical for precision measurement |
| Charge Injection (max) | 5pC - limits voltage glitch in sample-and-hold and switched-capacitor circuits |
| tON/tOFF | 35ns/25ns at +5V - supports >10MHz switching in test equipment and communications signal routing |
| ESD Protection | 2000V per Method 3015.7 - provides robust handling in manufacturing and field deployment |
| Leakage (max) | 10nA at +85°C - maintains accuracy in high-impedance sensor front-ends and medical ultrasound beamforming |
Pinout & Package
SOT23-6 package with exposed pad (EP); 6-pin surface-mount outline measuring 2.90mm × 2.90mm × 0.80mm (JEDEC MO-178AA). EP must be connected to V+ for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open terminal | Connects to COM only when IN = high; used for active-high signal path selection |
| 2 (COM) | Common analog terminal | Bidirectional I/O node; routes signal between NO and NC based on logic state |
| 3 (NC) | Normally Closed terminal | Connects to COM only when IN = low; provides default signal path without active drive |
| 4 (GND) | Ground reference | Return path for logic and analog circuitry; must be low-impedance for noise immunity |
| 5 (V+) | Positive supply | Single power rail for analog and digital sections; powers internal bias networks and transmission gates |
| 6 (IN) | Digital control input | TTL/CMOS-compatible logic input; high = connect COM to NO, low = connect COM to NC |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 2–10ns delay prevents momentary short between NO and NC paths during transition |
| RON matching | 2Ω max difference between channels - essential for matched gain/attenuation in differential signal routing |
| Low leakage | 100pA max at +25°C - preserves signal integrity in pH sensors, photodiode amplifiers, and electrophysiology front-ends |
| Rail-to-rail analog range | Supports signals from GND to V+ - eliminates need for external clamping diodes in wide-dynamic-range applications |
| Logic compatibility | Operates with 0V/3.3V, 0V/5V, or 0V/12V logic swings - simplifies integration with mixed-voltage FPGA/CPU 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 | SOT23-6 package with exposed pad (EP); same electrical specs but enhanced thermal dissipation | Better suited for continuous-duty industrial applications where junction temperature exceeds 85°C ambient | Select MAX4544EUT-T when PCB layout allows EP soldering and thermal management is critical |
| ADG1419BRMZ | 5.5Ω RON max at +5V; 1.5pC charge injection; requires dual ±15V or single +36V supply | Higher voltage capability but incompatible with +3.3V logic and low-voltage battery systems | Choose ADG1419BRMZ only for high-voltage (>12V) signal routing where ultra-low RON and charge injection outweigh supply complexity |
Compared with MAX4544EPA, MAX4544EUT-T offers identical functionality with improved thermal performance via EP connection, while ADG1419BRMZ trades low-voltage operation for superior RON and charge injection-making MAX4544EPA optimal for cost-sensitive, battery-powered, 3.3V/5V designs requiring guaranteed break-before-make.

FAQ
What is the maximum supply voltage rating for the MAX4544EPA?
The MAX4544EPA has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2.7V to +12V. Exceeding +13V risks permanent damage per Absolute Maximum Ratings. The MAX4544EPA maintains specified RON, leakage, and switching performance across this full 2.7V–12V range, making it suitable for both 3.3V microcontroller interfaces and 12V industrial backplanes.
Does the MAX4544EPA support rail-to-rail analog signal switching?
Yes, the MAX4544EPA supports rail-to-rail analog signals from GND to V+. Its transmission-gate design allows bidirectional signal flow with minimal distortion across the entire supply range. This capability eliminates the need for external clamping diodes in applications like audio routing or sensor multiplexing, and is explicitly confirmed in the Applications Information section of the MAX4544EPA datasheet.
Is break-before-make timing guaranteed for the MAX4544EPA?
Yes, break-before-make timing is guaranteed for the MAX4544EPA, with a minimum delay of 2ns and maximum of 10ns at +25°C (per Electrical Characteristics table). This feature prevents momentary shorting between NO and NC paths during logic transitions-critical for avoiding audible pops in audio systems or signal corruption in precision measurement setups using the MAX4544EPA.
What is the thermal resistance (θJA) of the MAX4544EPA in its plastic DIP package?
The MAX4544EPA in the 8-pin plastic DIP package has a thermal resistance (θJA) of 9.09°C/W, with continuous power dissipation rated at 727mW at +70°C (derating 9.09mW/°C above that temperature). This value is specified in the Absolute Maximum Ratings table and reflects standard JEDEC test conditions-important for thermal design when operating the MAX4544EPA near its 12V/60Ω RON power limit.
How does the MAX4544EPA compare to the MAX4543 in terms of topology and pin compatibility?
The MAX4544EPA is a single SPDT switch (1 COM, 1 NO, 1 NC), while the MAX4543 is a dual SPST device (two independent switches, one NO + one NC per channel) in an 8-pin package. They are not pin-compatible: MAX4544EPA uses SOT23-6 (6 pins), whereas MAX4543 variants use SOT23-8 or µMAX-8. Functionally, MAX4544EPA provides simpler single-path selection; MAX4543 enables independent control of two signal paths-so topology and footprint differ fundamentally despite shared family features.
