Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX488EESA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX488EESA  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage:** +4.5V to +5.5V  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** -40°C to +85°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 120µA (typical)  
- **Receiver Input Impedance:** ≥12kΩ  
- **Driver Output Short-Circuit Current Limit:** ±60mA  

### **Descriptions:**  
The MAX488EESA is a low-power, RS-485/RS-422 compliant transceiver designed for half-duplex communication. It features reduced slew-rate drivers to minimize EMI and reflections, making it suitable for long-distance data transmission. The device includes fail-safe circuitry to ensure a high receiver output state when inputs are open or shorted.  

### **Features:**  
- Low-power operation (120µA quiescent current)  
- Half-duplex communication  
- Enhanced slew-rate limiting for reduced EMI  
- Thermal shutdown protection  
- Receiver/driver enable control  
- ±15kV ESD protection on bus pins  
- Operates with a single +5V supply  
- Suitable for RS-485 and RS-422 applications  

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

Application Scenarios & Design Considerations

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers

Alternative Part Number

  • SP3485EN --: Pin-compatible RS-485 transceiver in SOIC-8 with similar 3.3V/5V operation and half-duplex interface, widely used as a MAX488 drop-in alternative.
  • SN75176BP --: Classic industry-standard RS-485 half-duplex transceiver in DIP-8/SOIC-8, functionally equivalent to MAX488 with well-established availability.
  • ADM485ARZ --: Low-power RS-485 transceiver in SOIC-8 offering comparable data rate and drive capability, suitable as a functional replacement for MAX488EESA.
  • SN75176BDR --: Industry-standard half-duplex RS-485 transceiver in SOIC-8, functionally equivalent with well-established availability and similar electrical characteristics.
  • SP485ECN-L --: RS-485 transceiver in SOIC-8 offering comparable functionality and ESD performance, suitable as a form-fit-function substitute.
