Description and Introduction

±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters The MAX3045BEUE+ is a quad, low-voltage, CMOS analog multiplexer manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Configuration:** Quad, 2:1 multiplexer  
- **Supply Voltage Range:** +2.7V to +12V (±2.7V to ±6V for dual supplies)  
- **On-Resistance (RON):** 120Ω (typical) at ±5V supply  
- **On-Resistance Matching (ΔRON):** 5Ω (max)  
- **Charge Injection:** 10pC (max)  
- **Bandwidth (-3dB):** 200MHz  
- **Switching Time (tON/tOFF):** 150ns (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-TSSOP (Thin Shrink Small Outline Package)  

### **Descriptions:**  
- The MAX3045BEUE+ is a high-performance, low-voltage CMOS analog multiplexer designed for precision signal routing.  
- It features low on-resistance, minimal charge injection, and high bandwidth, making it suitable for data acquisition, audio/video switching, and communication systems.  
- The device operates with single or dual power supplies and is compatible with TTL/CMOS logic levels.  

### **Features:**  
- **Low On-Resistance:** 120Ω (typical) ensures minimal signal distortion.  
- **Wide Supply Range:** Supports single (+2.7V to +12V) or dual (±2.7V to ±6V) supplies.  
- **Fast Switching:** 150ns maximum switching time for high-speed applications.  
- **High Bandwidth:** 200MHz -3dB bandwidth for signal integrity.  
- **Low Charge Injection:** 10pC (max) reduces glitches during switching.  
- **TTL/CMOS-Compatible Logic Inputs:** Ensures easy interfacing with digital circuits.  
- **ESD Protection:** ±15kV Human Body Model (HBM) for robustness.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
