Overview
The ISL31492EIBZ-T is a half-duplex, fault-protected RS-485/RS-422 differential transceiver powered by a single 5V supply. It supports data rates up to 250kbps with a typical quiescent current of 2.3mA and shutdown current of 10µA. The device features ±60V bus pin protection and an extended common mode range of ±25V. It operates within a temperature range of -40°C to +85°C and is housed in an 8-lead SOIC package.
Feature Summary
- Fault protection on RS-485 bus pins up to ±60V
- Extended common mode voltage tolerance of ±25V
- Full fail-safe receiver design for open, shorted, or idle bus conditions
- Hot plug circuitry maintaining three-state outputs during power transitions
Applications
- Utility meters and automated meter reading systems
- PROFIBUS and field bus networks
- Security camera networks
- Industrial process control networks
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm tape and reel packaging specifications. Confirm that the component meets RoHS compliance requirements and check for any relevant Product Change Notices affecting assembly or material composition prior to procurement.
Selection Notes
Select this component for applications requiring half-duplex communication with robust fault protection. Ensure the system design accommodates the 5V supply voltage and verify that the 250kbps data rate aligns with network timing requirements. Consider the 8-lead SOIC package dimensions for PCB layout constraints.
Part Context
This part belongs to the ISL3149xE series of fault-protected transceivers designed to exceed standard RS-485 and RS-422 requirements. The series offers various configurations including full and half-duplex options with different data rates and package types to suit diverse industrial communication needs.
Replacement Considerations
Consult the ISL32490E datasheet for exact replacement options if cable invert functionality is required. Verify compatibility with existing designs when considering alternative members of the ISL3149xE family.
