ISL83490IBZ-T

Product Overview

The ISL83490IBZ-T from Renesas Electronics Corporation is an Active integrated circuit transceiver for RS422 and RS485 interface applications. It is configured as a 1/1 device, providing one driver and one receiver in a full-duplex architecture. The part operates from a 3V ~ 3.6V supply and is specified for an ambient temperature range of -40°C ~ 85°C. It is supplied in an 8-SOIC surface-mount package, with a 50 mV receiver hysteresis and a 10Mbps data rate.

Key Features

• RS422 and RS485 protocol support in a full-duplex transceiver configuration.
• 1/1 driver/receiver count, with 50 mV receiver hysteresis.
• 10Mbps data rate and 3V ~ 3.6V supply voltage range.
• 8-SOIC surface-mount package for board-level implementation.
• Operating temperature range of -40°C ~ 85°C and Active lifecycle status.

Applications

• RS422 or RS485 communication links requiring transmission and reception paths.
• Full-duplex interface connections where one driver and one receiver are required.
• Surface-mount board designs using a 3V ~ 3.6V supply and an 8-SOIC package.

Design & Procurement Notes

When selecting this part, verify that the system provides a 3V ~ 3.6V supply and that the PCB footprint matches the 8-SOIC surface-mount package. The 1/1 full-duplex configuration suits designs requiring one driver and one receiver, while the 10Mbps data rate and 50 mV receiver hysteresis should be checked against the link requirements. Confirm the -40°C ~ 85°C operating range is suitable for the final assembly environment, and note the Active status for long-term procurement planning.
