Description and Introduction

±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters The MAX3042BCWE+ is a quad, low-voltage, CMOS analog multiplexer manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Configuration:** Quad 2:1 or dual 4:1 multiplexer  
- **Supply Voltage Range:** +2.7V to +12V (±2.7V to ±6V for dual supplies)  
- **On-Resistance (RON):** 120Ω (typical)  
- **On-Resistance Matching (ΔRON):** 4Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Off-Channel Leakage Current:** ±0.1nA (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Switching Time (tON/tOFF):** 150ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (WSO)  

### **Descriptions:**  
The MAX3042BCWE+ is a high-performance, low-voltage analog multiplexer designed for precision signal routing in industrial, communication, and test equipment applications. It offers low on-resistance, minimal charge injection, and high bandwidth, making it suitable for high-speed data acquisition and signal switching.  

### **Features:**  
- Low on-resistance (120Ω) and tight matching (4Ω)  
- Wide supply voltage range (+2.7V to +12V single supply, ±2.7V to ±6V dual supply)  
- High bandwidth (200MHz) for fast signal switching  
- Low charge injection (10pC) for minimal signal distortion  
- Low off-channel leakage current (±0.1nA)  
- TTL/CMOS-compatible logic inputs  
- ESD protection (≥2000V per Method 3015.7)  

The MAX3042BCWE+ is ideal for applications requiring high-speed, low-distortion signal switching in data acquisition, audio/video routing, and communication systems.
