Product details
Overview
MAX4624EUT-T from Maxim Integrated is a break-before-make SPDT analog switch optimized for low-voltage signal routing in battery-powered and space-constrained systems. It delivers 1Ω max on-resistance at +5V, 50ns max turn-on/turn-off times, and integrated overcurrent protection - enabling robust power and audio signal switching in portable electronics.
For engineers reviewing the MAX4624EUT-T datasheet, MAX4624EUT-T pinout, MAX4624EUT-T application, or MAX4624EUT-T equivalent, key selection criteria include guaranteed break-before-make timing, ±200mA continuous current handling, RON flatness ≤0.12Ω, and SOT23-6 package compatibility with legacy MAX4544 designs.
Technical Context
The MAX4624EUT-T implements a CMOS transmission-gate architecture with internal current-limit and thermal-shutdown circuitry triggered at ~1.2A overload. Its logic input accepts rail-to-rail voltages up to +5.5V independent of V+, supporting mixed-supply interfacing.
Switching behavior is strictly break-before-make (tBBM = 1–20ns), eliminating momentary short-circuit paths between NO and NC. Analog signal range spans full 0V to V+ (up to +5.5V), with bidirectional operation and minimal RON variation across voltage and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 1Ω max at +5V supply - enables <100mV drop at 100mA, critical for precision low-voltage signal integrity |
| RON flatness | 0.12Ω max - ensures consistent gain/attenuation across full analog signal range (0V to V+) |
| Switching speed | tON/tOFF ≤50ns max - supports high-speed multiplexing in data-acquisition and comms circuits |
| Supply range | +1.8V to +5.5V single supply - powers directly from Li-ion, 3.3V, or 5V rails without level shifting |
| Overcurrent threshold | 1.2A typical - provides self-protecting operation during short circuits or capacitive load charging |
| Logic compatibility | TTL-compatible at +5V - interfaces directly with microcontroller GPIO without external buffers |
| Leakage current | ±20nA max off-leakage - preserves signal fidelity in high-impedance sensor and audio paths |
Pinout & Package
MAX4624EUT-T is housed in a standard 6-pin SOT23-6 package (1.6mm × 2.9mm, 1.1mm height), compatible with automated PCB assembly and footprint-constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Digital control input | Inverts logic sense: high = connect COM to NO, low = connect COM to NC |
| 2 V+ | Positive supply | Accepts +1.8V to +5.5V; powers analog switch core and logic interface |
| 3 GND | Ground reference | Return path for supply and analog signals; must be low-impedance for leakage control |
| 4 NC | Normally closed analog terminal | Connected to COM when IN = low; open when IN = high |
| 5 COM | Common analog terminal | Bidirectional signal path - serves as input or output depending on channel state |
| 6 NO | Normally open analog terminal | Connected to COM when IN = high; open when IN = low |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Eliminates signal shorting during state transitions - essential for power routing and relay replacement |
| Overcurrent protection | Self-resetting current limit + thermal shutdown prevents latch-up or damage under sustained overload |
| Rail-to-rail logic inputs | IN accepts 0V to +5.5V regardless of V+ - simplifies interface with mixed-voltage controllers |
| Low RON flatness | 0.12Ω max variation across 0V–V+ range - maintains linearity in audio and sensor signal paths |
| SOT23-6 footprint compatibility | Pins match MAX4544 - allows drop-in upgrade to lower RON and added protection |
Applications

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 | No overcurrent protection; 2.5Ω max RON at +5V; same SOT23-6 pinout | Lacks fault resilience in power-switching roles; higher RON increases signal loss | Choose MAX4544EUT-T only if cost sensitivity outweighs protection and performance needs |
| TMUX1574DSGR | 1.5Ω max RON; no break-before-make guarantee; 1.8V–5.5V supply; 6-pin WSON | Different package (WSON-6); lacks tBBM specification - unsuitable where short-circuit prevention is mandatory | Select TMUX1574DSGR only for space-constrained WSON layouts where BMB timing is not safety-critical |
Compared with MAX4544EUT-T and TMUX1574DSGR, the MAX4624EUT-T uniquely combines guaranteed break-before-make timing, integrated overcurrent protection, and lowest RON in SOT23-6 - making it optimal for protected power routing and precision analog multiplexing where reliability and signal fidelity are prioritized.

FAQ
What is the guaranteed break-before-make delay for MAX4624EUT-T?
The MAX4624EUT-T guarantees a break-before-make delay (tBBM) of 1ns to 20ns across its full operating temperature range (–40°C to +85°C). This parameter is explicitly specified in the datasheet's Electrical Characteristics table and ensures no overlap between NC and NO conduction paths during switching - a critical requirement for preventing supply shorting in power-routing applications. The MAX4624EUT-T is the only variant in the MAX4624/MAX4625 family with this guaranteed timing behavior.
Does MAX4624EUT-T support rail-to-rail analog signal levels?
Yes, the MAX4624EUT-T supports analog signal levels from 0V to V+ (up to +5.5V), with minimal RON variation across that range. At +5V supply, RON flatness is guaranteed ≤0.12Ω, and typical RON remains below 1.2Ω even at VCOM = 0V or VCOM = V+. This rail-to-rail capability enables accurate switching of full-scale sensor outputs, audio waveforms, and battery-monitoring signals without clipping or distortion - a key advantage of the MAX4624EUT-T over older analog switches with limited voltage swing.
What overcurrent protection mechanism does MAX4624EUT-T implement?
The MAX4624EUT-T integrates dual-stage overcurrent protection: first, a current-limit circuit activates when the voltage drop across the on-resistance reaches ~0.6V (corresponding to ~1.2A at 0.5Ω), and second, thermal shutdown engages under sustained overload. Under short-circuit conditions, the device pulses - turning on for 1µs then off for 5ms - to limit power dissipation. This behavior is fully characterized in the datasheet's Typical Operating Characteristics (Figure MAX4624 toc10) and distinguishes the MAX4624EUT-T from unprotected alternatives like the MAX4544EUT-T.
Is MAX4624EUT-T pin-compatible with MAX4544EUT-T?
Yes, the MAX4624EUT-T is pin-compatible with the MAX4544EUT-T in the SOT23-6 package: both share identical pin 1 (IN) through pin 6 (NO) assignments and electrical pin functions. This allows direct PCB-level replacement to upgrade from 2.5Ω RON and no protection (MAX4544EUT-T) to 1Ω RON and integrated overcurrent protection (MAX4624EUT-T) without layout changes - a documented migration path confirmed in Maxim's ordering information and functional diagrams.
What is the maximum continuous current rating for MAX4624EUT-T?
The MAX4624EUT-T is rated for ±200mA continuous current between any analog terminal (NO, NC, or COM) and COM, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating temperature range and is supported by thermal design margins in the SOT23-6 package (571mW max power dissipation at +70°C). Exceeding ±200mA may trigger the overcurrent protection circuit, causing pulsing behavior - a safeguard explicitly designed into the MAX4624EUT-T to prevent damage during transient overloads.
