Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX248CQH is a low-power, +5V RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage:** +5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Common-Mode Voltage Range (Receiver):** -7V to +12V  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 16-pin QSOP (Quarter Small Outline Package)  

### **Descriptions:**
- The MAX248CQH is designed for half-duplex communication in RS-485/RS-422 networks.  
- It features low-power shutdown mode, reducing current consumption when not in use.  
- The device includes a fail-safe receiver, ensuring a logic-high output when inputs are open or shorted.  

### **Features:**
- **Low Power Consumption:** Operates at 120µA (typical) in shutdown mode.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Driver Short-Circuit Protection:** Withstands output short circuits.  
- **Thermal Shutdown:** Prevents damage from excessive power dissipation.  
- **Half-Duplex Operation:** Supports bidirectional data transmission on a single pair of wires.  

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