ISL32274EIVZ

Overview

The ISL32274EIVZ is a single-driver RS-422 interface integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V, supporting standard 3.3 V and 5 V logic levels. The device delivers data transmission rates up to 10 Mb/s with a quiescent power supply current of 800 uA. It features robust electrostatic discharge protection rated at +/- 15 kV according to the Human Body Model. The component is housed in a 16-lead Quad Dual Flat No-Lead (QD) package and is designed for operation across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides high-voltage ESD protection on all pins to safeguard against electrical stress.
• Offers low-power consumption suitable for battery-operated or energy-efficient systems.
• Supports reliable differential signaling for RS-422 communication standards.

Applications

• Industrial automation control networks
• Building management and security systems
• Data acquisition modules

Procurement Notes

Verify the specific suffix IVZ corresponds to the QD package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notices as availability may be restricted. Ensure moisture sensitivity level requirements are met during storage and handling procedures.

Selection Notes

Select this component when a single driver is required for RS-422 applications. Compare against quad-driver variants if multiple channels are needed. Verify that the 10 Mb/s speed meets system timing requirements. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the ISL3227xE series of RS-422/RS-485 interface devices. It complements receiver-only models like the ISL32273EFVZ and quad-driver versions such as the ISL32272E series. The series emphasizes ruggedness and low power for harsh industrial environments.

Replacement Considerations

Direct substitutes include other single-driver RS-422 transceivers from Renesas or competitors offering identical pinouts and electrical specifications. Verify package compatibility and thermal performance before substitution.
