- **Package:** 10-pin µMAX (3mm x 5mm)  

### **Description:**  
The MAX4634EUB+ is a high-performance, low-voltage analog multiplexer designed for precision signal routing in applications requiring fast switching and low distortion. It features low on-resistance and minimal charge injection, making it suitable for data acquisition, audio/video switching, and communication systems.  

### **Features:**  
- Single 8:1 or dual 4:1 multiplexer configuration  
- Low on-resistance (5Ω) and flatness (1.5Ω)  
- Wide supply voltage range (+2.7V to +12V single, ±2.7V to ±6V dual)  
- High bandwidth (200MHz) for signal integrity  
- Fast switching (35ns turn-on, 25ns turn-off)  
- Low charge injection (10pC) for minimal glitching  
- TTL/CMOS-compatible logic inputs  
- 10-pin µMAX package for space-constrained designs  

This device is ideal for applications requiring high-speed signal switching with minimal distortion.
