Product details
Overview
MAX4624EZT 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 operates from +1.8V to +5.5V, delivers 1Ω max on-resistance at +5V, 50ns max turn-on/turn-off time, and integrated overcurrent protection - enabling robust power and audio signal switching in portable electronics.
For engineers reviewing the MAX4624EZT datasheet, MAX4624EZT pinout, MAX4624EZT application, or MAX4624EZT equivalent, this device is selected for precision analog path control where low RON, fast switching, rail-to-rail signal handling, and fault resilience are critical in compact SOT23-6 layouts.
Technical Context
The MAX4624EZT implements CMOS transmission-gate architecture with guaranteed break-before-make timing (tBBM = 1–20ns), preventing momentary shorting during state transitions. Its analog signal range spans GND to V+, supporting bidirectional signal flow across COM, NO, and NC terminals without polarity constraints.
Overcurrent protection activates when the voltage drop across the on-switch reaches ~0.6V, initiating current-limiting behavior followed by thermal shutdown cycling (5ms off-time) under sustained overload - eliminating need for external current-sense circuitry in load-switch applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1Ω max at +5V supply - enables ≤100mA continuous analog or power routing with <5mV drop at full load. |
| RON Flatness | 0.12Ω max over full signal range - ensures minimal distortion in audio/video signals and high-accuracy data acquisition. |
| Switching Speed | tON/tOFF = 50ns max - supports >10MHz digital signal multiplexing and fast channel selection in communications circuits. |
| Supply Range | +1.8V to +5.5V single supply - compatible with Li-ion, 3.3V, and 5V logic domains without level shifters. |
| Logic Compatibility | TTL-compatible inputs at +5V - accepts standard 0.8V/2.4V thresholds; IN tolerates up to +5.5V regardless of V+. |
| Overcurrent Threshold | 1.2A typical trip point - protects downstream circuitry from shorts and excessive loads without external fusing. |
| Off-Leakage Current | ±20nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and low-power sleep modes. |
Pinout & Package
MAX4624EZT is housed in a 6-pin Thin SOT23 package (1.0mm height), optimized for PCB area savings and thermal performance in portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Inverts logic sense: high = connect COM to NO, low = connect COM to NC; rail-to-rail tolerant up to +5.5V. |
| 2 (V+) | Positive supply rail | Single power source for analog and logic sections; must be applied before analog signals to prevent latch-up. |
| 3 (GND) | Ground reference | Common return for supply, logic, and analog paths; decoupling capacitor required near V+/GND pins. |
| 4 (NC) | Normally closed analog terminal | Connected to COM when IN = low; open-circuit when IN = high; bidirectional signal path. |
| 5 (COM) | Common analog terminal | Central signal hub - routes to either NC or NO based on IN state; supports full V+ to GND swing. |
| 6 (NO) | Normally open analog terminal | Connected to COM when IN = high; open-circuit when IN = low; identical electrical specs to NC. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make switching | Eliminates signal shorting during transition - essential for power routing and relay replacement where cross-conduction must be avoided. |
| 1Ω max on-resistance at +5V | Minimizes insertion loss and self-heating in high-current analog paths, supporting ≥100mA continuous operation. |
| Integrated overcurrent and thermal protection | Automatically limits current and cycles off/on under overload - removes need for discrete current-sense ICs or fuses in load-switch designs. |
| 0.12Ω max RON flatness | Maintains consistent gain and linearity across full analog input range - critical for audio fidelity and precision instrumentation. |
| 6-pin Thin SOT23 package (1.0mm height) | Reduces board footprint by >30% vs. standard SOT23 - ideal for ultra-thin mobile devices and wearables. |
Applications
| Battery Power Routing | Audio Signal Switching |
|---|---|

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 pinout and RON (1Ω), but lacks overcurrent protection and has slower tON/tOFF (100ns). | Suitable only in non-fault-tolerant signal-routing roles where protection is handled externally. | Select MAX4544EUT-T if cost sensitivity outweighs protection needs and layout reuse is mandatory. |
| TMUX6219DSGR | Higher RON (2.1Ω), wider supply (1.8V–5.5V), no integrated overcurrent protection, but offers 1.5pC lower charge injection. | Better for ultra-low-distortion sensor muxing; unsuitable for power routing or short-circuit-prone environments. | Choose TMUX6219DSGR when charge injection dominates design priority and fault resilience is managed elsewhere. |
Compared with MAX4544EUT-T and TMUX6219DSGR, the MAX4624EZT uniquely combines guaranteed break-before-make timing, sub-1Ω RON, and autonomous overcurrent response - making it the only option among the three qualified for protected power-path switching in portable systems.

FAQ
What is the guaranteed break-before-make delay for MAX4624EZT?
The MAX4624EZT guarantees a break-before-make delay (tBBM) of 1ns to 20ns across its full operating temperature range (-40°C to +85°C), ensuring no overlap between NC and NO conduction states during switching. This specification is validated per Figure 3a in the official MAX4624/MAX4625 datasheet and is intrinsic to the MAX4624EZT's internal timing architecture - not dependent on external loading or supply voltage.
Does MAX4624EZT support rail-to-rail analog signal switching?
Yes, the MAX4624EZT supports rail-to-rail analog signal switching from GND to V+ across COM, NO, and NC terminals. Its CMOS transmission-gate design maintains low and flat on-resistance (≤0.12Ω variation) over the full voltage range when V+ = +5V, enabling undistorted passage of audio, sensor, and data signals without clipping or gain compression - a key capability confirmed in the Typical Operating Characteristics plots (toc01, toc02).
What overcurrent protection behavior does MAX4624EZT exhibit under a direct short?
Under a direct short, the MAX4624EZT detects overcurrent within 1µs and pulses the output ON for 1µs before remaining OFF for 5ms - repeating this cycle until the fault clears. This behavior is specified in the datasheet's "Overcurrent-Protection Current Threshold" section and verified in Figure toc10. The MAX4624EZT's protection is autonomous and requires no external components, distinguishing it from unprotected alternatives like the MAX4544EUT-T.
Can MAX4624EZT operate from a +3.3V supply while accepting +5V logic inputs?
Yes, the MAX4624EZT supports independent logic and supply voltage domains: it functions correctly with V+ = +3.3V while accepting IN logic levels up to +5.5V (exceeding TTL thresholds of 0.6V/2.0V). This rail-to-rail input tolerance is explicitly documented in the "Logic Inputs" section and Electrical Characteristics table, allowing direct interfacing with higher-voltage microcontrollers without level-shifting circuitry - a verified feature of the MAX4624EZT.
Is MAX4624EZT pin-compatible with MAX4544EUT-T?
Yes, the MAX4624EZT is pin-compatible with the MAX4544EUT-T in the 6-pin SOT23-6 package, sharing identical pin assignments (IN, V+, GND, NC, COM, NO) and footprint. This compatibility is stated in the "Pin Compatible with MAX4544" feature list and Ordering Information table - enabling drop-in replacement in existing layouts where enhanced protection and speed are needed, though MAX4544EUT-T lacks overcurrent protection and has slower switching.
