ISL3153EIBZ

Overview

The ISL3153EIBZ is a half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 5V supply and supports data rates up to 12 Mb/s. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It is housed in a 14-pin SOIC package with an operating temperature range of -40°C to +85°C. Key electrical characteristics include a high output voltage swing and low shutdown current.

Feature Summary

• Integrated IEC 61000-4-2 electrostatic discharge protection for robust bus communication
• High-voltage differential output capability for reliable signal transmission over long distances
• Low power consumption with dedicated shutdown mode for energy efficiency

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IBZ' corresponds to the standard SOIC-14 tube packaging variant. Check for RoHS compliance documentation and ensure the part status aligns with current availability, as lifecycle changes may affect long-term sourcing.

Selection Notes

Select this component when designing systems requiring RS-485 or RS-422 interfaces with high ESD immunity. Ensure the application environment stays within the specified -40°C to +85°C temperature range. Verify that the 12 Mb/s maximum data rate meets system timing requirements and that the 14-pin SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISL315xE series of ruggedized interface transceivers. It shares functional similarities with other members like the ISL3152E and ISL3155E but differs in pin count and specific performance metrics such as data rate and package type. The series is designed for harsh industrial environments requiring reliable serial communication.

Replacement Considerations

Direct substitutes include the ISL3153EIUZ (MSOP-10 package) for space-constrained designs, though pinout differences require schematic review. Other family members like the ISL3152EIBZ offer similar functionality in an 8-pin SOIC package but with lower data rates.
