Description and Introduction

±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters The MAX3042BCSE+ is a quad, low-voltage, CMOS analog multiplexer (MUX) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Configuration:** 4-channel (4:1) multiplexer  
- **Supply Voltage Range:** +1.8V to +5.5V  
- **On-Resistance (RON):** 4Ω (typical at +3V supply)  
- **Low On-Resistance Flatness:** 0.5Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin narrow SOIC (CSE)  

### **Descriptions & Features:**  
- **Low Voltage Operation:** Supports +1.8V to +5.5V single-supply operation.  
- **Low On-Resistance:** Ensures minimal signal distortion.  
- **High Bandwidth:** Suitable for high-speed signal switching.  
- **Low Charge Injection:** Reduces glitches during switching.  
- **Break-Before-Make Switching:** Prevents signal overlap.  
- **TTL/CMOS-Compatible Logic Inputs:** Ensures easy interfacing with digital controllers.  
- **ESD Protection:** Up to ±2kV (Human Body Model).  

The MAX3042BCSE+ is commonly used in data acquisition, audio/video switching, and communication systems.
