Description and Introduction

+3V-powered, low-power, true RS-232 tranceiver. The MAX212CAG is a high-performance, low-power, dual-supply RS-232 transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX212CAG  
- **Type:** RS-232 Transceiver  
- **Supply Voltage (VCC):** +3V to +5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Data Rate:** Up to 120kbps  
- **Number of Drivers/Receivers:** 3 Drivers / 5 Receivers  
- **Package:** 24-pin SSOP (Shrink Small Outline Package)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:** Typically 5mA in shutdown mode  

### **Descriptions:**  
- The MAX212CAG is a 3V to 5.5V-powered RS-232 transceiver designed for serial communication applications.  
- It integrates charge-pump circuitry to generate RS-232 voltage levels from a single supply, eliminating the need for external ±12V supplies.  
- The device is compliant with EIA/TIA-232 and V.28/V.24 standards.  

### **Features:**  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **Auto-Shutdown & Auto-Wakeup:** Reduces power consumption when inactive.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Three-State Outputs:** Allows multiple transceivers to share a common bus.  
- **On-Chip Charge Pump:** Generates RS-232 compliant ±5.5V outputs from a single 3V to 5.5V supply.  
- **Wide Supply Voltage Range:** Operates from +3V to +5.5V.  

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