Description and Introduction

±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters The MAX3040CSE+ is a quad, low-voltage, CMOS analog multiplexer (mux) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Configuration:** 4-channel (4:1) multiplexer  
- **Supply Voltage Range:** +2.7V to +12V (single supply) or ±2.7V to ±6V (dual supply)  
- **On-Resistance (RON):** 120Ω (typical) at ±5V supply  
- **On-Resistance Matching:** 5Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Switching Time (tON/tOFF):** 150ns (max)  
- **Leakage Current (OFF):** ±0.1nA (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 16-pin narrow SOIC (CSE+)  

### **Description:**  
The MAX3040CSE+ is a high-performance, low-voltage analog multiplexer designed for precision signal routing in mixed-signal applications. It features low on-resistance, minimal charge injection, and high bandwidth, making it suitable for data acquisition, audio/video switching, and communication systems.  

### **Features:**  
- Low on-resistance (120Ω) for minimal signal distortion  
- Wide supply voltage range (single or dual supply)  
- Fast switching speed (150ns max)  
- High off-isolation and crosstalk rejection  
- Low charge injection reduces glitches  
- TTL/CMOS-compatible logic inputs  
- ESD protection on all pins (≥2kV HBM)  

The device is RoHS-compliant and operates reliably in industrial and consumer applications.
