- **Common-Mode Input Voltage Range:** -7V to +12V  

### **Descriptions:**  
The MAX3089CPD is a high-speed, low-power 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 at data rates up to 10Mbps and includes enhanced ESD protection, making it robust in industrial environments.  

### **Features:**  
- **High-Speed Data Transmission:** Supports up to 10Mbps.  
- **Wide Common-Mode Range:** -7V to +12V for noise immunity.  
- **Low Power Consumption:** 120µA typical supply current.  
- **ESD Protection:** ±15kV (HBM) on bus pins.  
- **Half-Duplex Operation:** Suitable for bidirectional communication.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Receiver Fail-Safe:** Ensures a logic-high output when inputs are open or shorted.  
- **Industrial Temperature Range:** 0°C to +70°C.

Application Scenarios & Design Considerations

Fail-Safe / High-Speed 10Mbps / Slew-Rate-Limited RS-485/RS-422 Transceivers

Alternative Part Number

  • SP490CP --: Pin-compatible RS-485/RS-422 transceiver in DIP-14 with similar full-duplex capability, a common drop-in substitute for MAX3089 designs.
  • SN75176BP --: Widely available RS-485 differential bus transceiver in DIP-8; functionally similar signaling but check pinout and duplex requirements before use.
  • ADM485AN --: Low-power RS-485 transceiver in DIP-8 from a reputable vendor, suitable as a functional alternative when board layout can be adapted.
  • SP3491CN-L --: Pin-compatible RS-485/RS-422 transceiver in 14-pin PDIP with similar data rate and supply voltage, direct drop-in replacement.
  • ADM485ANZ --: Low-power RS-485 transceiver in 8-pin PDIP with comparable signaling characteristics, suitable alternative when board layout allows.
