Description and Introduction

3.5Ω, Single 8:1 and Dual 4:1, Low-Voltage Analog Multiplexers The MAX4639EUE+T is a high-speed, low-voltage, single-supply CMOS analog multiplexer (MUX) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** +1.8V to +5.5V  
- **On-Resistance (RON):** 4Ω (typical at +4.5V supply)  
- **On-Resistance Flatness:** 0.5Ω (typical)  
- **Charge Injection:** 5pC (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Switching Time (tON/tOFF):** 25ns/20ns (typical)  
- **Leakage Current (OFF):** 1nA (typical at +25°C)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-TSSOP  

### **Descriptions:**  
- The MAX4639EUE+T is a single 8-channel (or dual 4-channel) analog multiplexer designed for high-speed signal switching.  
- It is optimized for low-voltage operation, making it suitable for battery-powered and portable applications.  
- The device offers low on-resistance and minimal signal distortion, ensuring high signal integrity.  

### **Features:**  
- **Low Voltage Operation:** Works down to +1.8V.  
- **Low On-Resistance:** 4Ω typical for minimal signal attenuation.  
- **High Bandwidth:** 200MHz for high-frequency applications.  
- **Fast Switching:** 25ns turn-on and 20ns turn-off times.  
- **Low Charge Injection:** Reduces glitches during switching.  
- **Break-Before-Make Switching:** Prevents signal overlap.  
- **TTL/CMOS-Compatible Logic Inputs:** Ensures easy interfacing with digital circuits.  
- **ESD Protection:** ±15kV Human Body Model (HBM) for robustness.  

This device is commonly used in data acquisition systems, audio/video switching, communication systems, and test equipment.

Application Scenarios & Design Considerations

3.5Ω, Single 8:1 and Dual 4:1, Low-Voltage Analog Multiplexers

Alternative Part Number

  • ADG736BRMZ --: Dual SPDT analog switch with similar low on-resistance and wide supply range, pin-compatible in function and a common drop-in replacement for the MAX4639 family.
  • TS5A23159DGSR --: Dual SPDT analog switch offering comparable RON and supply voltage range, widely available and functionally equivalent for signal routing applications.
  • DG2715DQ-T1-E3 --: Dual SPDT CMOS analog switch with similar electrical characteristics and low power consumption, suitable as an alternative when the Maxim part is unavailable.
