Product details
Overview
MAX4636EUB-TG075 from Maxim Integrated is a dual single-pole/double-throw (SPDT) CMOS analog switch with 4Ω max on-resistance at +5V, 14ns max turn-on time, and rail-to-rail signal handling from +1.8V to +5.5V supply. It features independent channel control, 1Ω max on-resistance flatness, and -65dB off-isolation at 1MHz-optimized for audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4636EUB-TG075 datasheet, MAX4636EUB-TG075 pinout, MAX4636EUB-TG075 application, or MAX4636EUB-TG075 equivalent, key selection criteria include guaranteed on-resistance matching (≤0.2Ω), break-before-make timing (≤1ns), THD of 0.1%, low leakage (<0.3nA), and compatibility with 1.8V logic interfaces while operating from 3.3V or 5V supplies.
Technical Context
The MAX4636EUB-TG075 implements two independent SPDT switches in a 10-pin µMAX package, using CMOS process technology with matched transistor pairs to ensure ≤0.2Ω on-resistance matching between channels. Its logic inputs accept up to +5.5V regardless of V+ level, enabling direct interfacing with 5V logic while powered from +3.3V.
Switching behavior follows non-inverted logic (IN high = NO-to-COM path closed), with guaranteed break-before-make operation (≤1ns) and rail-to-rail analog signal range (GND to V+). Charge injection is limited to 2pC (typ) at +5V, supporting precision sample-and-hold and low-distortion audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 4Ω at +5V supply - enables <10mV drop at 2.5mA signal current, suitable for precision sensor multiplexing. |
| On-Resistance Match | 0.2Ω max between channels - ensures balanced gain/attenuation in differential or stereo signal paths. |
| Turn-On / Turn-Off Time | 14ns / 6ns max - supports >30MHz digital signal switching and fast ADC channel scanning. |
| Rail-to-Rail Signal Range | GND to V+ - preserves full dynamic range of baseband audio and sensor outputs without clipping. |
| Off-Isolation | -65dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-source routing. |
| Total Harmonic Distortion | 0.1% - maintains fidelity in line-level audio applications with 600Ω source/load impedance. |
| Supply Voltage Range | +1.8V to +5.5V - allows direct integration into battery-powered systems (e.g., 2-cell Li-ion) and mixed-voltage PCBs. |
Pinout & Package
MAX4636EUB-TG075 is housed in a 10-pin µMAX package (3mm × 3mm, 0.8mm height), RoHS-compliant with lead-free finish. The package has no exposed thermal pad and uses gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN1 | Logic control input for Switch 1 | Active-high signal enabling NO1-to-COM1 path; accepts 0–5.5V logic regardless of V+ voltage. |
| 2 NO1 | Normally open terminal, Switch 1 | Connects to COM1 only when IN1 = high; bidirectional analog node with 9pF off-capacitance. |
| 3 GND | Ground reference | Return path for supply and logic; must be low-impedance to minimize THD and crosstalk. |
| 4 NO2 | Normally open terminal, Switch 2 | Independent of Switch 1; used for stereo left/right or dual-sensor routing. |
| 5 IN2 | Logic control input for Switch 2 | Enables NO2-to-COM2 path; decoupled from IN1 for asynchronous channel control. |
| 6 COM2 | Common terminal, Switch 2 | Analog I/O node supporting rail-to-rail signals; connects to NO2 or NC2 based on IN2 state. |
| 7 NC2 | Normally closed terminal, Switch 2 | Connected to COM2 when IN2 = low; provides default signal path during power-up or logic reset. |
| 8 V+ | Positive supply input | +1.8V to +5.5V analog/digital supply; bypass capacitor (0.1µF) required near pin for noise immunity. |
| 9 NC1 | Normally closed terminal, Switch 1 | Default path for Switch 1; complements NO1 for SPDT functionality in relay-replacement designs. |
| 10 COM1 | Common terminal, Switch 1 | Primary analog interface point; low 32pF on-capacitance minimizes bandwidth loss in high-frequency paths. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance flatness | 1Ω max over full signal range at +5V - ensures consistent gain across audio band (20Hz–20kHz). |
| Low charge injection | 2pC typical - reduces voltage glitch in sample-and-hold circuits and prevents DAC output disturbance. |
| Break-before-make timing | 1ns max - eliminates momentary short-circuit between NO and NC paths during switching transitions. |
| Logic-level tolerant inputs | VIN up to +5.5V independent of V+ - eliminates need for external level shifters when interfacing with 5V microcontrollers. |
| Ultra-low leakage current | ±0.3nA max off-leakage - preserves accuracy in high-impedance sensor front-ends and battery-monitoring circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4636ETB+TG104 | Same electrical specs; 10-pin 3×3mm thin QFN package with exposed thermal pad. | Better thermal performance (1951mW dissipation vs. 330mW) and higher vibration resistance; requires different land pattern. | Select for high-density layouts needing improved power handling or extended temperature stability beyond +85°C ambient. |
| ADG726BRUZ | 6Ω max RON at +5V; 17ns tON; -60dB off-isolation; 16-pin TSSOP package. | Higher channel count (dual 4:1 mux vs. dual SPDT); larger footprint; lacks 1.8V logic compatibility. | Choose when system requires 4-input multiplexing per channel or needs ADI's enhanced ESD robustness (±4kV HBM), not SPDT simplicity. |
Compared with MAX4636ETB+TG104, the MAX4636EUB-TG075 offers identical switching performance in a smaller µMAX footprint but lower thermal headroom; versus ADG726BRUZ, it delivers faster switching, lower distortion, and true 1.8V logic support-making it optimal for space-constrained, low-power audio and sensor routing.

FAQ
What is the maximum supply voltage rating for MAX4636EUB-TG075?
The absolute maximum supply voltage (V+) for MAX4636EUB-TG075 is +6V. Operation above this level risks permanent damage. The device is specified for reliable operation from +1.8V to +5.5V, with on-resistance and switching speed degrading slightly below +2.7V. Always observe proper power-supply sequencing-apply V+ before analog signals-to avoid latch-up or ESD diode conduction.
Does MAX4636EUB-TG075 support rail-to-rail analog signal operation?
Yes, MAX4636EUB-TG075 supports true rail-to-rail analog signal handling from GND to V+, with minimal on-resistance variation across the full range. At +5V supply, on-resistance flatness is guaranteed ≤1Ω, and THD remains at 0.1% with 600Ω source/load. This enables accurate buffering and routing of baseband audio, sensor outputs, and DAC signals without clipping or gain compression.
How does the logic polarity of MAX4636EUB-TG075 differ from MAX4635EUB?
MAX4636EUB-TG075 uses non-inverted logic: IN1 or IN2 high enables the NOx-to-COMx path. In contrast, MAX4635EUB uses inverted logic-IN high disconnects NO and connects NC. Both share identical electrical specs and pinout, so swapping them requires inverting control signals in firmware or hardware. The MAX4636EUB-TG075 datasheet explicitly states "MAX4635 has inverted logic compared to MAX4636" to prevent misapplication.
Can MAX4636EUB-TG075 interface directly with 5V logic while powered from 3.3V?
Yes, MAX4636EUB-TG075 logic inputs (IN1, IN2) tolerate voltages up to +5.5V independent of V+, allowing direct connection to 5V microcontrollers or FPGAs even when V+ = +3.3V. No level-shifting circuitry is needed. Input leakage remains <100nA, and VIH/VIL thresholds scale with V+ (VIH = 2.0V min at +3V supply), ensuring robust noise margins in mixed-voltage systems containing MAX4636EUB-TG075.
What is the thermal performance difference between MAX4636EUB-TG075 and MAX4636ETB+TG104?
MAX4636EUB-TG075 in µMAX package has a 330mW maximum power dissipation at +70°C (derating 4.7mW/°C above), while MAX4636ETB+TG104 in thin QFN offers 1951mW (derating 24.4mW/°C). The QFN's exposed pad enables superior heat transfer, making it preferable for high-duty-cycle or elevated ambient temperature use. The µMAX version remains optimal for ultra-compact layouts where thermal load is low-e.g., intermittent audio switching or sensor polling at <1kHz.
