Product details
Overview
MAX4625EUT+TG035 from Maxim Integrated is a make-before-break SPDT analog switch optimized for low-voltage signal routing, featuring 1Ω max on-resistance at +5V, 50ns max turn-on/turn-off time, and integrated overcurrent protection. It operates from a single +1.8V to +5.5V supply and is used in battery-powered audio/video multiplexing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4625EUT+TG035 datasheet, MAX4625EUT+TG035 pinout, MAX4625EUT+TG035 application, or MAX4625EUT+TG035 equivalent, key selection criteria include guaranteed make-before-break timing, RON flatness ≤0.12Ω, TTL-compatible logic inputs at +5V, and SOT23-6 package compatibility with PCB space-constrained portable designs.
Technical Context
The MAX4625EUT+TG035 implements a CMOS transmission-gate architecture with internal current-limit and thermal-shutdown circuitry that activates at ~1.2A overcurrent threshold. Its digital control input accepts rail-to-rail logic levels up to +5.5V independent of V+, enabling mixed-supply interfacing.
It supports bidirectional analog signal routing across the full 0V to V+ range with minimal RON variation (≤0.15Ω flatness at +5V), and guarantees tMBB ≤6ns at +25°C - critical for glitch-free channel switching in audio and sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1Ω max at +5V - enables ≤200mA continuous analog current with <5mV drop at 100mA. |
| RON Flatness | 0.12Ω max at +5V - ensures consistent gain/attenuation across 0–5V signal swing in precision mux applications. |
| Switching Speed | tON/tOFF = 50ns max - supports ≥10MHz digital control rates and fast signal path reconfiguration. |
| Make-Before-Break Delay | tMBB = 1ns min / 6ns max - prevents signal dropout during channel transitions in audio routing. |
| Supply Range | +1.8V to +5.5V single supply - allows direct interface with Li-ion battery (3.0–4.2V) and 3.3V/5V logic domains. |
| Overcurrent Threshold | 1.2A typical - protects downstream circuitry during short-circuit events without external fusing. |
| Logic Compatibility | TTL-compatible at +5V (VINH = 2.4V, VINL = 0.8V) - eliminates level-shifter need in legacy 5V microcontroller interfaces. |
Pinout & Package
MAX4625EUT+TG035 is housed in a standard 6-pin SOT23-6 package (1.6mm × 2.9mm × 1.1mm), compatible with automated pick-and-place and reflow soldering. The Thin SOT variant (1.0mm height) is recommended for new 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. |
| 2 - V+ | Positive supply rail | Single power source for analog and digital sections; must be applied before analog signals. |
| 3 - GND | Ground reference | Common return for supply, logic, and analog paths; requires low-impedance PCB connection. |
| 4 - NC | Normally closed analog terminal | Connected to COM when IN = low; open when IN = high - used for default-path routing. |
| 5 - COM | Common analog port | Bidirectional node: accepts or delivers analog signals to either NC or NO based on IN state. |
| 6 - NO | Normally open analog terminal | Connected to COM when IN = high; open when IN = low - used for active-path selection. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed make-before-break switching | Ensures uninterrupted signal continuity during channel transition - essential for audio mute-free switching. |
| Integrated overcurrent protection | Combines current-limit and thermal shutdown to prevent latch-up or damage during shorts or capacitive loads. |
| Rail-to-rail logic input tolerance | Accepts 0V to +5.5V logic regardless of V+ - simplifies interface with mixed-voltage FPGAs or microcontrollers. |
| Low charge injection (65pC max) | Minimizes voltage glitches at COM during switching - critical for high-resolution ADC/DAC multiplexing. |
| 0.12Ω RON matching between channels | Reduces gain error in differential or dual-channel signal paths - improves accuracy in instrumentation muxes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4625EUT-T | Identical electrical specs and pinout; differs only in tape-and-reel packaging (TG035 = cut-tape, EUT-T = reel). | No functional difference; same thermal, timing, and reliability performance across temperature range. | Select MAX4625EUT+TG035 for prototyping or low-volume builds requiring cut-tape delivery. |
| TS5A23157DCKR | Lower RON (0.9Ω typ at 3.3V) but no overcurrent protection; tMBB not guaranteed; 1.65–5.5V supply. | Suitable for cost-sensitive, non-fault-tolerant signal routing where protection is handled externally. | Choose TS5A23157DCKR only if overcurrent protection is implemented at system level and tighter RON is prioritized. |
Compared with MAX4625EUT-T, MAX4625EUT+TG035 offers identical functionality in cut-tape form for flexible procurement; versus TS5A23157DCKR, it trades slightly higher RON for integrated fault protection and guaranteed make-before-break timing - critical for robust field-deployed equipment.

FAQ
What is the guaranteed make-before-break timing specification for MAX4625EUT+TG035?
The MAX4625EUT+TG035 guarantees a make-before-break delay (tMBB) of 1ns minimum to 6ns maximum at +25°C, with operation across the full -40°C to +85°C temperature range. This parameter is explicitly characterized in the datasheet's Electrical Characteristics table under "Make-Before-Break Delay" and ensures zero signal interruption during channel switching - a key differentiator from break-before-make alternatives like the MAX4624EUT+TG035.
Does MAX4625EUT+TG035 support analog signals beyond the supply rails?
No, MAX4625EUT+TG035 does not support analog signals beyond the supply rails. The absolute maximum rating specifies that voltages on COM, NO, and NC pins must remain within -0.3V to (V+ + 0.3V). Internal clamping diodes limit excursion, but sustained operation outside 0V to V+ degrades RON and may trigger overcurrent protection. For overvoltage-tolerant routing, external protection diodes (as shown in Figure 1 of the datasheet) are required.
Can MAX4625EUT+TG035 operate from a 3.3V supply while interfacing with 5V logic?
Yes, MAX4625EUT+TG035 supports this configuration: its digital input (IN) accepts rail-to-rail logic levels up to +5.5V regardless of V+, so a 3.3V-powered MAX4625EUT+TG035 can directly accept 5V logic signals without level shifting. This is confirmed in the Applications Information section and Electrical Characteristics table (VINH = 2.4V min at +5V supply, with tolerance extended to +5.5V).
What is the maximum continuous current rating for MAX4625EUT+TG035 at 3.3V supply?
At +3.3V supply, MAX4625EUT+TG035 supports ±200mA continuous current through the COM–NO or COM–NC path, as specified in the Absolute Maximum Ratings table. While RON increases to 2Ω max at +3V (per Electrical Characteristics), the 200mA limit remains unchanged and is constrained by package thermal dissipation and bond-wire integrity - not RON-dependent I²R heating alone.
Is MAX4625EUT+TG035 pin-compatible with the MAX4544 series?
Yes, MAX4625EUT+TG035 is pin-compatible with the MAX4544 series, as explicitly stated in the General Description: "The MAX4624/MAX4625 are pin compatible with the MAX4544." Both share identical SOT23-6 pinout (IN, V+, GND, NC, COM, NO), enabling drop-in replacement in existing layouts - provided the make-before-break behavior of MAX4625EUT+TG035 aligns with system timing requirements.
