Product details
Overview
MAX4544ESA+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, 25ns max turn-off time, and guarantees break-before-make switching - ideal for audio/video multiplexing and sample-and-hold circuits in portable instrumentation.
For engineers reviewing the MAX4544ESA+T datasheet, MAX4544ESA+T pinout, MAX4544ESA+T application, or MAX4544ESA+T equivalent, key selection criteria include SPDT topology with guaranteed break-before-make timing, SOT23-6 package compatibility, low leakage (<10nA at +85°C), rail-to-rail analog signal handling (0V to V+), and TTL/CMOS logic compatibility across supply voltages.
Technical Context
The MAX4544ESA+T implements a CMOS transmission-gate architecture optimized for bidirectional analog signal switching with minimal distortion. Its internal structure enforces strict break-before-make timing (2ns–10ns delay) between NC and NO paths during state transitions, preventing momentary short-circuits in critical signal chains.
It supports rail-to-rail analog inputs (0V to V+) and logic inputs driven from 0V to V+, enabling direct interfacing with microcontrollers and DACs without level-shifting. The device maintains <6Ω RON flatness and ≤2Ω channel-to-channel RON matching under +5V operation, ensuring consistent gain and minimal crosstalk (-90dB typical).

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 electrical specs; top mark AAAM vs ESA+T's ESA marking; identical pinout and thermal performance | No functional difference - both rated for -40°C to +85°C; EUT-T uses tape-and-reel packaging for automated assembly | Select EUT-T for high-volume SMT production; ESA+T suits prototyping and low-volume PCB assembly |
| ADG1419BRMZ | SPDT switch with 4.7Ω typical RON, 16.5V max supply, but requires dual ±15V or single 12V supply; no guaranteed break-before-make | Higher voltage capability suits industrial PLC I/O modules; lacks break-before-make - unsuitable for fault-sensitive routing | Choose only if higher supply voltage (>12V) or lower RON is mandatory; verify absence of short-through during switching |
Compared with MAX4544ESA+T, MAX4544EUT-T offers identical performance in a production-optimized reel format, while ADG1419BRMZ trades guaranteed break-before-make for wider supply range and lower RON - making it viable only where timing safety is secondary to voltage headroom.

FAQ
What is the maximum analog signal voltage range supported by the MAX4544ESA+T?
The MAX4544ESA+T supports analog signals from 0V to V+ - meaning its full signal range tracks the positive supply rail. When operated from +5V, it switches signals from 0V to +5V without clipping or increased on-resistance; at +12V supply, the range extends to 0V to +12V. This rail-to-rail capability eliminates external biasing in unipolar systems and ensures consistent RON flatness across the entire span. The MAX4544ESA+T achieves this using fully enhanced CMOS transmission gates with matched P- and N-channel devices.
Does the MAX4544ESA+T require external pull-up or pull-down resistors on its IN pin?
No, the MAX4544ESA+T does not require external pull-up or pull-down resistors on the IN pin. Its logic inputs are TTL/CMOS compatible and internally biased to recognize 0.8V as logic low and 2.4V as logic high when powered from +5V. With other supplies (e.g., +3.3V or +12V), the thresholds scale proportionally, and rail-to-rail driving (0V to V+) is guaranteed. The MAX4544ESA+T draws only ±1µA input current, so microcontroller GPIOs can drive it directly without loading concerns.
Can the MAX4544ESA+T be used in a bidirectional signal path?
Yes, the MAX4544ESA+T is fully bidirectional: the COM, NO, and NC terminals have no intrinsic directionality. Signals may flow from COM to NO, NO to COM, COM to NC, or NC to COM with identical RON, leakage, and charge injection characteristics. This makes the MAX4544ESA+T suitable for applications like shared bus arbitration, duplex audio routing, and reconfigurable sensor interfaces where signal direction changes dynamically during operation.
What is the thermal performance of the MAX4544ESA+T in SOT23-6 package?
The MAX4544ESA+T in SOT23-6 has a power dissipation limit of 571mW at +70°C ambient, derating by 7.1mW/°C above that temperature. At maximum rated junction temperature (+125°C), its usable power drops to ~190mW. The package's small size (2.9mm × 2.8mm) demands careful PCB layout: use ≥2cm² copper pour connected to GND under the exposed pad area (if present - though ESA+T variant does not utilize EP) and minimize trace lengths to reduce thermal resistance. The MAX4544ESA+T maintains full electrical specs across -40°C to +85°C case temperature.
How does the break-before-make timing of the MAX4544ESA+T prevent signal corruption?
The MAX4544ESA+T guarantees a minimum 2ns and maximum 10ns break interval between NC opening and NO closing (or vice versa) during logic transitions. This enforced gap prevents momentary short-circuiting of two analog sources - a critical safeguard in applications like relay replacement, power domain isolation, or redundant signal selection. Without it, transient shorts could cause latch-up, ground bounce, or data corruption. The MAX4544ESA+T achieves this via internal delay circuitry synchronized to the IN pin edge, independent of supply voltage or temperature.
