ISL3174EIBZ-T

Overview

The ISL3174EIBZ-T is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 500 kb/s. The device features ±15kV IEC61000 ESD protection on the bus pins and full fail-safe receiver functionality. It utilizes an SOIC-8 surface-mount package with an operating temperature range of -40°C to +85°C. Key electrical parameters include a maximum quiescent current of 800µA and a common-mode voltage range of -7V to +12V.

Feature Summary

• Full fail-safe receiver design ensures a logic high output when inputs are floating, shorted, or undriven.
• Integrated ±15kV IEC61000 electrostatic discharge protection on RS-485 input/output pins.
• Hot-plug capability maintains three-state outputs during power-up sequences.

Applications

• Industrial automation networks requiring robust node connectivity
• Building automation systems utilizing RS-485 communication protocols
• Utility meter reading concentrators

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the SOIC-8 footprint matches the target PCB layout dimensions prior to procurement.

Selection Notes

Select this component for applications requiring 500 kb/s data throughput with integrated ESD protection. Compare against higher-speed variants like the ISL3177E if faster transmission is required. Verify that the 3.3V supply voltage aligns with the system power architecture.

Part Context

This part belongs to the ISL317xE family of low-power, high-speed RS-485/RS-422 transceivers. The family shares common features such as true 1/8 unit load capability and thermal shutdown protection, allowing for extensive bus topologies without repeaters.

Replacement Considerations

ISL3174EIUZ-T: Identical functional specifications but housed in an MSOP-8 package instead of SOIC-8. Verify pin compatibility and board space constraints before substitution.
