Product details
Overview
MAX4636EUB+TG35 from Maxim Integrated is a dual single-pole/double-throw (SPDT) CMOS analog switch in 10-pin µMAX package, operating from +1.8V to +5.5V supply with 4Ω max on-resistance at +5V, 14ns max turn-on time, and rail-to-rail signal handling. It serves as a low-power, high-speed signal routing device in portable audio/video systems and battery-powered data-acquisition circuits.
For engineers reviewing the MAX4636EUB+TG35 datasheet, MAX4636EUB+TG35 pinout, MAX4636EUB+TG35 application, or MAX4636EUB+TG35 equivalent, key selection criteria include guaranteed on-resistance flatness (≤1Ω), break-before-make timing (≤1ns), low crosstalk (−67dB @ 1MHz), and logic-level tolerance up to +5.5V independent of V+.
Technical Context
The MAX4636EUB+TG35 implements two independently controlled SPDT switches using CMOS process technology, with noninverting logic control (IN1/IN2 directly enable NOx-to-COMx paths). Its architecture guarantees break-before-make switching to prevent momentary shorting between NC and NO terminals during state transitions.
Signal path design supports bidirectional analog operation across the full supply rail range (GND to V+), with leakage currents ≤±0.3nA over temperature and charge injection ≤2pC at +5V supply - critical for precision sample-and-hold and low-distortion audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 4Ω at +5V supply - enables ≤10mA continuous current per channel without significant voltage drop |
| On-Resistance Flatness (max) | 1Ω over full signal range at +5V - ensures minimal THD (<0.1%) in audio-frequency paths |
| Turn-On Time (max) | 14ns - supports >50MHz digital signal routing and fast multiplexing in data acquisition |
| Off-Isolation (min) | −65dB at 1MHz - suppresses coupling between inactive channels in multi-signal systems |
| Crosstalk (min) | −67dB at 1MHz - maintains signal integrity when routing adjacent analog sources |
| Supply Range | +1.8V to +5.5V - allows direct interface with 1.8V, 3.3V, and 5V logic domains without level shifters |
| Logic Input Tolerance | +5.5V absolute max on IN1/IN2 - permits 5V logic drive while V+ = +3.3V |
Pinout & Package
The MAX4636EUB+TG35 uses a 10-pin µMAX package (3.0mm × 3.0mm × 0.8mm, no exposed pad), optimized for space-constrained PCB layouts in portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Logic control input for Switch 1 | Noninverting enable: HIGH connects NO1 to COM1; LOW connects NC1 to COM1 |
| 2 (NO1) | Normally open terminal, Switch 1 | Signal path closed to COM1 only when IN1 = HIGH; floating otherwise |
| 3 (GND) | Ground reference | Return path for supply and logic; must be low-impedance for leakage and noise control |
| 4 (NO2) | Normally open terminal, Switch 2 | Signal path closed to COM2 only when IN2 = HIGH; isolated when LOW |
| 5 (IN2) | Logic control input for Switch 2 | Noninverting enable: HIGH connects NO2 to COM2; LOW selects NC2 |
| 6 (COM2) | Common terminal, Switch 2 | Bidirectional I/O node shared between NO2 and NC2; handles rail-to-rail analog signals |
| 7 (NC2) | Normally closed terminal, Switch 2 | Signal path closed to COM2 only when IN2 = LOW; open when HIGH |
| 8 (V+) | Positive supply input | Single power rail for analog and digital sections; decoupling required within 1cm |
| 9 (NC1) | Normally closed terminal, Switch 1 | Signal path closed to COM1 only when IN1 = LOW; open when HIGH |
| 10 (COM1) | Common terminal, Switch 1 | Bidirectional I/O node shared between NO1 and NC1; supports ±100mA pulsed current |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog range spans GND to V+ - eliminates clipping in DC-coupled audio and sensor interfaces |
| Guaranteed break-before-make | ≤1ns interval prevents NC–NO shorting during switching - essential for relay replacement safety |
| Low on-resistance match | ≤0.2Ω max difference between channels - enables precise matched-path applications like differential switching |
| Ultra-low leakage | ≤±0.3nA off-state current - preserves accuracy in high-impedance sample-and-hold and medical sensor front-ends |
| Low THD | 0.1% over 20Hz–20kHz - meets fidelity requirements for consumer and pro-audio signal routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4636ETB+ | Same electrical specs, but in 3mm × 3mm thin QFN (exposed pad); thermal resistance 24.4mW/°C vs. µMAX's 4.7mW/°C | Better power dissipation in high-duty-cycle or ambient >70°C environments | Select MAX4636ETB+ for thermally demanding layouts; MAX4636EUB+TG35 preferred for legacy µMAX footprint compatibility |
| ADG726BRUZ | 2.5Ω max RON at +5V, 10ns tON, but only +1.8V to +5.5V supply; no guaranteed break-before-make | Lacks documented BBM timing - unsuitable where channel shorting must be avoided | Choose ADG726BRUZ only when lower on-resistance outweighs BBM requirement; verify system-level fault tolerance |
Compared with MAX4636ETB+ and ADG726BRUZ, the MAX4636EUB+TG35 provides optimal trade-off of proven break-before-make reliability, µMAX footprint compatibility, and industry-standard 4Ω on-resistance - making it the preferred choice for space-limited, safety-critical analog routing where layout reuse matters.

FAQ
What is the maximum allowable supply voltage for MAX4636EUB+TG35?
The MAX4636EUB+TG35 has an absolute maximum V+ rating of +6V. Operation above +5.5V violates the recommended operating conditions and risks permanent damage. The device is specified for reliable operation from +1.8V to +5.5V, with on-resistance and switching speed degrading outside this range. Always observe the −0.3V to +6V limit on V+ relative to GND.
Does MAX4636EUB+TG35 support rail-to-rail analog signals?
Yes, the MAX4636EUB+TG35 supports rail-to-rail analog signal handling: its analog inputs (COM_, NO_, NC_) operate from GND to V+ with minimal on-resistance variation. This is confirmed by the "Analog Signal Range" specification (0 to V+ volts) and typical operating curves showing RON flatness across the full voltage range - enabling DC-coupled audio, sensor, and data-acquisition applications without level-shifting.
What is the logic polarity of MAX4636EUB+TG35 compared to MAX4635EUB?
The MAX4636EUB+TG35 uses noninverting logic: a HIGH on IN1 or IN2 connects the respective NO_ terminal to COM_. In contrast, the MAX4635EUB uses inverted logic - HIGH selects NC_, LOW selects NO_. This functional difference is explicitly stated in the General Description and Pin Configuration diagrams. Interchanging them without logic inversion will reverse switch states.
Can MAX4636EUB+TG35 be used with a 3.3V supply while interfacing to 5V logic inputs?
Yes, the MAX4636EUB+TG35 logic inputs (IN1, IN2) tolerate voltages up to +5.5V regardless of V+ level. When V+ = +3.3V, applying +5V to IN1/IN2 is fully compliant and requires no external level translation - a key feature confirmed in the Applications Information section and Electrical Characteristics tables for both +5V and +3V supplies.
What is the guaranteed break-before-make time for MAX4636EUB+TG35?
The MAX4636EUB+TG35 guarantees a break-before-make (BBM) time of ≤1ns, measured under standard test conditions (VNO_/VNC_ = 3V, RL = 300Ω, CL = 35pF). This parameter is explicitly listed in the +5V Supply Electrical Characteristics table and ensures no overlap between NC_ and NO_ conduction paths - critical for preventing shorts in relay-replacement and multiplexer applications.
