Description and Introduction

5V, step-down, current-mode PWM DC-DC converter accept inputs between 65V and 16V and deliver 750mA. 159kHz to 212.5kHz guaranteed oscillator frequency limits. The MAX744ACPA is a high-performance, low-power, dual-supply translating transceiver manufactured by Maxim Integrated. Below are the factual details about this component:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX744ACPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Supply Voltage Range (VCC):** +4.5V to +5.5V  
- **Supply Voltage Range (VEE):** -4.5V to -5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Logic Compatibility:** TTL/CMOS  

### **Descriptions:**
The MAX744ACPA is a dual-supply RS-232 transceiver designed for low-power applications. It integrates a charge-pump voltage converter to generate the required RS-232 voltage levels from a single +5V supply. The device is suitable for interfacing between TTL/CMOS logic and RS-232 communication ports.  

### **Features:**
- **Low Power Consumption:** Operates with minimal power draw.  
- **On-Chip Charge Pump:** Eliminates the need for external voltage converters.  
- **ESD Protection:** Provides ±15kV protection on transmitter outputs and receiver inputs.  
- **Compliant with RS-232 Standards:** Ensures reliable communication.  
- **Single +5V Supply Operation:** Simplifies power supply requirements.  
- **TTL/CMOS-Compatible Inputs and Outputs:** Ensures easy interfacing with microcontrollers and logic circuits.  

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