Description and Introduction

10kV ESD-Protected / Quad 5V RS-485/RS-422 Transmitters The MAX3040CWE is a quad, low-voltage, CMOS analog switch manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** +2.7V to +12V (single supply) or ±2.7V to ±6V (dual supply).  
- **On-Resistance (RON):** 45Ω (typical) at ±5V supply.  
- **On-Resistance Matching:** 4Ω (typical).  
- **Charge Injection:** 10pC (typical).  
- **Off-Leakage Current:** 0.1nA (typical) at +25°C.  
- **Bandwidth (-3dB):** 200MHz (typical).  
- **Crosstalk:** -90dB (typical) at 1MHz.  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** 16-pin Wide SOIC (WSO).  

### **Descriptions:**  
- The MAX3040CWE is a precision, quad, SPST (Single-Pole Single-Throw) analog switch.  
- It is designed for low-voltage, high-speed signal switching applications.  
- Features low on-resistance and high bandwidth, making it suitable for audio, video, and data routing.  
- TTL/CMOS-compatible logic inputs for easy interfacing with digital circuits.  

### **Features:**  
- Low on-resistance (45Ω).  
- Wide supply voltage range (±2.7V to ±6V or +2.7V to +12V).  
- Fast switching (tON = 50ns, tOFF = 35ns).  
- Low power consumption (<0.1µW).  
- Break-before-make switching action.  
- High off-isolation (-90dB at 1MHz).  
- ESD protection (>2kV per method 3015.7).  

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