ISL3152EIPZ

Overview

The ISL3152EIPZ is a single half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 4.5V to 5.5V supply and supports data rates up to 115kbps. The device features ±16.5kV IEC61000-4-2 ESD protection on bus I/O pins and withstands ±100V transient overvoltage. It provides a typical output voltage of 3.1V into a 54Ω load, ensuring high noise immunity. The receiver inputs offer full fail-safe functionality, guaranteeing a logic high output when inputs are open or shorted. With a true 1/8 unit load, the component allows for up to 256 devices on the bus. It operates within a temperature range of -40°C to +85°C and is available in an 8-pin MSOP package.

Feature Summary

• High ESD protection withstanding ±16.5kV IEC61000-4-2 strikes without latch-up
• Full fail-safe receiver design ensures defined logic state during open or shorted input conditions
• Hot plug capability maintains high-impedance driver and receiver outputs during power transitions
• Low bus current consumption constituting a true 1/8 unit load for extended network scalability

Applications

• Remote utility meter reading systems requiring high node counts
• Industrial automation networks utilizing RS-485 or RS-422 protocols
• Building automation and control systems
• Data acquisition systems with long bus segments

Procurement Notes

Verify the specific suffix 'IPZ' indicates the MSOP package variant when sourcing. Confirm RoHS compliance status through official Renesas documentation or authorized distributor certificates. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component for applications requiring robust ESD protection and high noise immunity in 5V systems. The 1/8 unit load characteristic makes it suitable for dense bus topologies supporting up to 256 nodes. Consider the 115kbps data rate limit; higher speed variants like the ISL3155E may be necessary for faster communication needs. Verify that the half-duplex configuration aligns with the system's bidirectional communication requirements.

Part Context

The ISL3152EIPZ belongs to the ISL315xE family of 5V powered RS-485/RS-422 transceivers. This family includes both half-duplex and full-duplex options with varying data rate capabilities. The IPZ suffix specifically denotes the 8-lead MSOP package format, distinguishing it from SOICN variants like the ISL3152EIBZ. The series is designed for rugged environments demanding high reliability and fault tolerance.

Replacement Considerations

ISL3152EIBZ offers identical electrical performance in an SOIC-8 package. ISL3155E provides increased data rates up to 20Mbps while maintaining similar ESD and fail-safe features. ISL3172E is a 3.3V compatible alternative with lower shutdown current but requires voltage level adjustment.
