Overview
The ISL3156EIBZ-T is a single RS-485/RS-422 differential transceiver manufactured by Renesas Electronics. It operates on a single 5V supply and supports data rates up to 20 Mb/s. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It includes a full-fail-safe receiver that guarantees a high logic level when the differential input is open or undriven. Packaged in a 14-pin SOIC, it functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrated IEC 61000-4-2 electrostatic discharge protection for robust industrial communication
- Full fail-safe receiver design ensuring defined output states during bus idle conditions
- Slew-rate limited transmitter to minimize electromagnetic interference emissions
Applications
- Industrial automation networks requiring reliable half-duplex communication
- Building automation systems utilizing RS-485 bus topologies
- Process control instrumentation with exposed communication interfaces
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required voltage domain and interface standard before integration into the final assembly.
Selection Notes
Select this component for applications requiring high-speed RS-485 transmission with integrated ESD protection. Confirm compatibility with the system's 5V power rail and verify that the 14-pin SOIC footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the ISL315xE series of low-power, high-speed RS-485/RS-422 transceivers. It is designed for harsh environments where signal integrity and protection against electrical disturbances are critical for maintaining network stability.
Replacement Considerations
Consult official Renesas cross-reference guides for verified substitutes. Generic equivalents may lack the specific IEC 61000 ESD ratings or fail-safe characteristics documented for this model.
