ISL32430EIBZ-T7A

Overview

The ISL32430EIBZ-T7A is a full-duplex RS-422 and RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within a 14-pin SOIC package. The device operates at data rates up to 250 kbps with a supply voltage range of 3V to 5.5V. It supports an extended operating temperature range from -40°C to +85°C and features a receiver input hysteresis of 30 mV for noise immunity. This component is designed for reliable serial communication in industrial environments.

Feature Summary

• Supports full-duplex RS-422 and RS-485 communication protocols
• Integrated ESD protection mechanisms for signal line robustness
• Operates across a wide industrial temperature range

Applications

• Industrial automation control systems
• Building automation networks
• Factory floor sensor interfaces

Procurement Notes

Verify the current lifecycle status, as this specific part number may be discontinued or subject to production changes. Confirm that the 14-SOIC package dimensions match the target PCB footprint. Ensure compliance with RoHS3 standards if required by the final assembly specifications before procurement.

Selection Notes

Select this component when a full-duplex interface is required rather than half-duplex alternatives like the ISL32457. The 14-pin package accommodates additional pins for power management or diagnostic functions not present in 8-pin variants. Verify that the 250 kbps speed meets the system timing requirements.

Part Context

This part belongs to the ISL3243xE family of high-performance RS-422/RS-485 transceivers. It shares the core electrical characteristics with other members of the series but differs in pin count and package configuration. The T7A suffix indicates tape and reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Check for direct replacements such as the ISL32430EIBZ (non-tape version) or updated Renesas equivalents. Cross-reference pinouts carefully when substituting with generic RS-485 transceivers to ensure compatibility with the 14-pin layout.
