ISL32174EFBZ

Drivers, Receivers, Transceivers Overview

The ISL32174EFBZ is a single-driver RS-422 interface integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device delivers a data rate of 10 Mb/s and features low quiescent current consumption of 800 uA. It provides robust electrostatic discharge protection rated at 15 kV. The component is housed in a 16-lead SOIC package and is designed for operation across an extended temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Single driver configuration for RS-422 differential signaling
• High ESD protection rating of 15 kV for harsh environments
• Low power consumption with 800 uA operating current
• Extended industrial temperature range capability

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication
• Data acquisition networks with high noise immunity needs
• Building automation and security system interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix BZ indicates the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notices as this component series may have limited availability. Ensure moisture sensitivity level requirements are met during storage and handling procedures.

Drivers, Receivers, Transceivers Selection Notes

Select this part when only a single transmitter channel is required for RS-422 applications. Compare against transceiver models if receiver functionality is also needed. Verify that the 10 Mb/s speed meets system timing requirements. Ensure the 16-pin SOIC footprint fits the target PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ISL32274E/ISL32174E family of RS-422 drivers. It shares core electrical specifications with other members but differs in package type and pinout configuration. The BZ suffix specifically denotes the standard plastic small outline package variant used in surface-mount assemblies.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the ISL32174EFVZ (TSSOP-16 package) or ISL32174EFRZ (QFN package). These alternatives maintain identical electrical performance but require different footprints. Cross-reference datasheets to ensure pin compatibility before substitution.
