Description and Introduction

10kV ESD-Protected / Quad 5V RS-485/RS-422 Transmitters The MAX3045BCUE is a quad, low-voltage, CMOS analog multiplexer 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:** ±4.5V to ±20V (dual supply) or +4.5V to +36V (single supply)  
- **On-Resistance (RON):** 120Ω (typical)  
- **On-Resistance Matching (ΔRON):** 4Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Off-Channel Leakage Current:** ±0.1nA (typical at +25°C)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Crosstalk:** -86dB (typical at 1MHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TSSOP (BCUE suffix)  

### **Descriptions:**
- The MAX3045BCUE is a high-performance, quad, single-pole, single-throw (SPST) analog switch.  
- It is designed for precision signal routing in low-voltage applications.  
- The device offers low on-resistance and fast switching, making it suitable for audio, video, and data acquisition systems.  

### **Features:**
- Low on-resistance (120Ω) and tight matching (4Ω)  
- Wide supply voltage range (±4.5V to ±20V or +4.5V to +36V)  
- High bandwidth (200MHz) for signal integrity  
- Low charge injection (10pC) for minimal distortion  
- Low crosstalk (-86dB) for improved isolation  
- TTL/CMOS-compatible logic inputs  
- ESD protection (≥2000V per Method 3015.7)  

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