Description and Introduction

20A / 1.8-Unit-Load / Slew-Rate-Limited RS-485 Transceivers The MAX1483CSA is a low-power, high-speed RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated
- **Part Number:** MAX1483CSA
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)
- **Supply Voltage Range:** +4.75V to +5.25V
- **Data Rate:** Up to 2.5Mbps
- **Operating Temperature Range:** 0°C to +70°C
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver
- **ESD Protection:** ±15kV (Human Body Model)
- **Quiescent Current (Shutdown Mode):** 1µA (typical)
- **Common-Mode Input Voltage Range:** -7V to +12V
- **Half-Duplex Operation**
- **Compliant with RS-485 and RS-422 Standards**

### **Descriptions:**
The MAX1483CSA is a low-power, high-speed transceiver designed for RS-485 and RS-422 communication. It features a single driver and receiver, making it suitable for half-duplex applications. The device operates from a single +5V supply and includes thermal shutdown and short-circuit protection.

### **Features:**
- **Low Power Consumption:** 120µA (typical) supply current.
- **High-Speed Data Transmission:** Supports data rates up to 2.5Mbps.
- **ESD Protection:** ±15kV protection on driver outputs and receiver inputs.
- **Shutdown Mode:** Reduces power consumption to 1µA (typical).
- **Short-Circuit Protection:** Driver outputs are protected against short circuits.
- **Thermal Shutdown:** Prevents damage from excessive power dissipation.
- **Wide Common-Mode Range:** Allows operation in noisy environments.
- **Half-Duplex Operation:** Suitable for bidirectional communication on a single pair of wires.

This information is based solely on the manufacturer's datasheet for the MAX1483CSA.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • SN75176BDR --: Industry-standard RS-485/RS-422 transceiver with the same half-duplex function and 8-pin SOIC footprint, widely available and pin-compatible in most designs.
  • SP485ECN-L --: Pin-compatible RS-485 transceiver in 8-pin SOIC with similar data rate and supply range, offering a direct drop-in option from a different vendor.
  • ISL8485EIBZ --: Half-duplex RS-485 transceiver with comparable electrical characteristics and 8-pin SOIC package, suitable as a functional replacement.
  • ISL8483EIBZ --: RS-485/RS-422 transceiver in SOIC-8 with comparable ESD protection and low power consumption, suitable drop-in alternative.
