ISL32174EFVZ

Overview

The ISL32174EFVZ is a quad RS-422 driver integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device delivers data rates up to 32 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 TSSOP package with an exposed pad for thermal management. It functions as a driver-only interface without integrated receivers.

Feature Summary

• Provides four differential drivers compliant with RS-422 standards for reliable serial communication
• Integrates high-level ESD protection to safeguard against electrostatic discharge events
• Supports extended industrial operating temperatures ranging from -40°C to +125°C
• Features low power consumption suitable for battery-operated or energy-efficient applications

Applications

• Industrial control systems requiring robust serial communication interfaces
• Data acquisition equipment needing high-speed differential signaling
• Communication modules operating in electrically noisy environments
• Embedded systems utilizing RS-422 bus architectures

Procurement Notes

Verify the specific suffix EFVZ to confirm the 16-TSSOP package type and lead-free RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard tube packaging configuration. Confirm moisture sensitivity level handling requirements during storage and assembly processes to maintain component integrity.

Selection Notes

Select this component when only differential transmission capability is required without integrated reception. Compare against transceiver variants if bidirectional communication is necessary. Verify that the 32 Mb/s speed limit meets system timing requirements. Ensure the 16-pin footprint fits the available PCB real estate constraints.

Part Context

This part belongs to the ISL3217xE series of RS-422 interface devices. It complements receiver and transceiver models within the same family, offering a specialized solution for unidirectional data transmission. The series shares common electrical characteristics and pinout compatibility where applicable, facilitating modular design strategies.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISL3217x family. Verify equivalent drive strength and ESD ratings before substituting. Confirm that any replacement maintains the same 16-TSSOP package dimensions and thermal performance specifications.
