Product details
Overview
MAX4634ETB-TG104 from Maxim Integrated is a fast, low-voltage, 4-channel CMOS analog multiplexer with 4Ω (max) on-resistance, 18ns turn-on time, and ±0.1nA off-leakage at +25°C. It operates from a single +1.8V to +5.5V supply, supports V+ to GND analog signal routing, and is packaged in a 10-pin, 3mm × 3mm TDFN-EP package. It is used in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4634ETB-TG104 datasheet, MAX4634ETB-TG104 pinout, MAX4634ETB-TG104 application, or MAX4634ETB-TG104 equivalent, key selection criteria include guaranteed RON matching (≤0.3Ω), RON flatness (≤1Ω), -80dB off-isolation at 1MHz, TTL/CMOS logic compatibility, and exposed-pad thermal performance in space-constrained portable designs.
Technical Context
The MAX4634ETB-TG104 implements a CMOS-based 4:1 analog multiplexer architecture with dual address inputs (A0, A1) and an active-high enable (EN). Its switch matrix routes one of four NOx inputs to the common (COM) terminal under digital control, with break-before-make timing (8ns typ) preventing signal shorting during channel transitions.
All channels support rail-to-rail analog signal handling (GND to V+), operate over -40°C to +85°C, and feature internal ESD protection diodes. The exposed pad (EP) is internally tied to GND and requires connection to a PCB ground plane for optimal thermal dissipation and signal integrity-critical for maintaining <0.018% THD in audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω (max) at +5V - ensures minimal voltage drop and gain error in precision signal paths |
| RON Matching | 0.3Ω (max) between channels - enables accurate ratiometric measurements across multiple sensor inputs |
| RON Flatness | 1Ω (max) over full signal range - maintains consistent gain and linearity for 0V–V+ signals |
| Turn-On / Turn-Off Time | 18ns / 11ns - supports high-speed multiplexing in sampling systems up to ~30MHz effective rate |
| Off-Isolation | -80dB at 1MHz - suppresses crosstalk between inactive channels in multi-signal routing |
| Analog Signal Range | GND to V+ - allows direct interfacing with unbuffered sensors, DACs, and ADCs without level-shifting |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V) - interoperable with both 3.3V and 5V microcontrollers without translators |
Pinout & Package
MAX4634ETB-TG104 is housed in a 10-pin, 3mm × 3mm TDFN-EP package with an exposed thermal pad (EP) internally connected to GND. The package supports high-density layout and enhanced thermal performance in compact portable electronics.

| 2 (NO1) | Normally Open Switch 1 | Analog input terminal for channel 1; rated for ±50mA continuous current |
| 3 (GND) | Ground Reference | Primary return path for analog and digital currents; connects to EP for thermal stability |
| 4 (NO3) | Normally Open Switch 3 | Analog input terminal for channel 3; identical RON and leakage specs as NO1–NO4 |
| 5 (EN) | Enable Input | Active-high control: drives all switches to high-Z when low; no pull-up required |
| 6 (V+) | Positive Supply | +1.8V to +5.5V single supply; bypass with 10µF capacitor near pin for noise immunity |
| 7 (NO4) | Normally Open Switch 4 | Analog input terminal for channel 4; supports same signal range and bandwidth as others |
| 8 (COM) | Common Analog Terminal | Output node shared across all channels; handles bidirectional analog signals (GND to V+) |
| 9 (NO2) | Normally Open Switch 2 | Analog input terminal for channel 2; matches RON and flatness within 0.3Ω/1Ω limits |
| 10 (A1) | Address Input | Selects channel index MSB; synchronous with A0 for 4-channel decoding (00–11) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports GND-to-V+ signals without clipping or distortion-enables direct connection to sensors and DACs |
| Guaranteed RON flatness ≤1Ω | Maintains amplitude consistency across full input voltage range, critical for precision instrumentation |
| -80dB off-isolation at 1MHz | Minimizes interference between inactive channels in multi-source audio or sensor aggregation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG714BRUZ | 8-channel, 4.5Ω RON (max), +3V to +5.5V supply, 16-TSSOP package | Higher channel count but larger footprint; lacks exposed thermal pad and 1.8V operation | Choose ADG714BRUZ only if 8-channel density outweighs size, thermal, and low-voltage requirements. |
| TS5A3159DCKR | Single-pole double-throw, 0.75Ω RON (max), +1.65V to +5.5V, SC70-6 package | SPDT topology only; no 4:1 functionality; superior RON but no address decoding or EN pin | TS5A3159DCKR suits point-to-point switching; MAX4634ETB-TG104 is required for 4-input selection with logic control. |
Compared with ADG714BRUZ and TS5A3159DCKR, the MAX4634ETB-TG104 uniquely combines 4:1 multiplexing, 1.8V operation, TDFN-EP thermal performance, and guaranteed RON matching-making it optimal for miniaturized, battery-critical systems requiring precision analog routing.

FAQ
What is the maximum supply voltage rating for the MAX4634ETB-TG104?
The MAX4634ETB-TG104 has an absolute maximum supply voltage (V+) of +6V. Operation must be limited to +1.8V to +5.5V per specifications; exceeding +6V risks permanent damage. The device includes internal clamping diodes on analog and digital pins, but these are not intended for sustained overvoltage protection-external diodes are recommended if signal voltages may exceed V+.
Does the MAX4634ETB-TG104 support 1.8V logic-level control inputs?
Yes, the MAX4634ETB-TG104 supports 1.8V logic-level control. Its digital inputs (A0, A1, EN) have guaranteed TTL/CMOS-compatible thresholds (+0.8V low, +2.4V high) and function correctly with 1.8V, 3.3V, or 5V logic families. No level-shifting circuitry is needed when interfacing with modern low-voltage MCUs or FPGAs.
How does the exposed pad (EP) on the MAX4634ETB-TG104 affect thermal performance?
The exposed pad (EP) on the MAX4634ETB-TG104 is internally connected to GND and must be soldered to a large PCB ground plane. This reduces thermal resistance by over 50% compared to non-EP packages, enabling reliable operation at +85°C ambient with typical power dissipation. Failure to connect EP degrades thermal performance and may cause parametric drift or premature failure.
Can the MAX4634ETB-TG104 handle bipolar analog signals?
No, the MAX4634ETB-TG104 is specified for unipolar analog signals only-from GND to V+. It cannot pass signals below GND or above V+ without risk of forward-biasing internal protection diodes, which increases leakage and distorts performance. For true bipolar operation, a dual-supply analog switch or external level-shifting circuitry is required.
What is the significance of the 0.3Ω RON matching specification for the MAX4634ETB-TG104?
The 0.3Ω (max) RON matching specification for the MAX4634ETB-TG104 means the difference between the highest and lowest on-resistance values across all four channels remains ≤0.3Ω under identical conditions. This tight matching ensures consistent gain and minimal offset error when using the device for ratiometric measurements-such as reading multiple resistive sensors into a single ADC.
