Description and Introduction

20A, 1.8-Unit-Load, Slew-Rate-Limited RS-485 Transceivers The MAX1482CPD is a high-speed, low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1482CPD  
- **Package:** 14-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage:** +5V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** 0°C to +70°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Quiescent):** 300µA (typical)  
- **Common-Mode Input Voltage Range:** -7V to +12V  
- **Output Short-Circuit Current Limit:** Yes  

### **Description:**  
The MAX1482CPD is a low-power, high-speed transceiver designed for RS-485/RS-422 communication. It features a single driver and receiver, making it suitable for half-duplex applications. The device includes slew-rate limiting to reduce EMI and minimize reflections in improperly terminated cables.  

### **Features:**  
- **Low Power Consumption:** 300µA supply current in shutdown mode.  
- **High-Speed Operation:** Supports data rates up to 2.5Mbps.  
- **Slew-Rate Limited for Reduced EMI:** Improves signal integrity.  
- **ESD Protection:** ±15kV protection on bus pins.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Driver Output Short-Circuit Current Limiting:** Enhances reliability.  
- **Receiver Fail-Safe:** Ensures a logic-high output when inputs are open or shorted.  

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

Application Scenarios & Design Considerations

20A, 1.8-Unit-Load, Slew-Rate-Limited RS-485 Transceivers

Alternative Part Number

  • SP483CP --: Pin-compatible low-power RS-485/RS-422 transceiver in DIP-8, functionally equivalent to the MAX1482 with similar data rate and supply range.
  • SN75176BP --: Industry-standard RS-485 differential bus transceiver in DIP-8, widely available and commonly used as a drop-in substitute for MAX1482 applications.
  • ADM485ANZ --: Low-power RS-485 transceiver in DIP-8 with comparable speed and drive capability, suitable replacement when exact MAX1482 features are not critical.
  • ADM485JN --: Low-power RS-485 transceiver in DIP-8 with comparable performance and pinout, suitable replacement when MAX1482 is unavailable.
