ISL3156EIUZ-T7A

Overview

The ISL3156EIUZ-T7A is a single RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates with a fixed supply voltage of 5 V and supports data rates up to 20 Mb/s. The device features one driver and one receiver, housed in an MSOP-10 surface-mount package. It functions within a temperature range of -40°C to +85°C and includes a shutdown mode for power reduction.

Feature Summary

• Supports high-speed differential communication at 20 Mb/s
• Integrated IEC 61000-4-2 electrostatic discharge protection
• Includes shutdown capability to minimize quiescent current

Applications

• Industrial fieldbus networks requiring robust noise immunity
• Building automation systems utilizing RS-485 protocols
• Data acquisition modules operating in electrically noisy environments

Procurement Notes

Verify the specific suffix T7A corresponds to the reel packaging configuration required for automated assembly processes. Confirm that the MSOP-10 footprint matches the target PCB layout dimensions. Ensure compatibility with standard 5V logic levels before finalizing procurement orders.

Selection Notes

Select this component when a single half-duplex RS-485 interface is needed with integrated ESD protection. It serves as a suitable alternative to other variants in the ISL315xE family that may offer different pin counts or lower data rate capabilities. Verify thermal requirements against the specified operating temperature range.

Part Context

This part belongs to the ISL315xE series of ruggedized RS-485/RS-422 transceivers. The series is characterized by high electromagnetic interference immunity and low power consumption. The manufacturer transitioned from Intersil to Renesas Electronics during corporate restructuring.

Replacement Considerations

ISL3156EIBZ-T7A: Identical electrical specifications with SOIC-8 packaging instead of MSOP-10.
