ISL83483IBZ

Product Overview

The Renesas Electronics Corporation ISL83483IBZ is a half-duplex RS422 and RS485 transceiver for serial data links. It integrates one driver and one receiver in an 8-SOIC surface-mount package, with a 3 V to 3.6 V supply range and a 250 kbps data rate. The receiver provides 50 mV hysteresis, and the device operates from -40°C to 85°C. The package is an 8-SOIC (0.154", 3.90 mm Width) for surface-mount assembly.

Design & Procurement Notes

Designers should match the ISL83483IBZ to a 3 V to 3.6 V supply and a serial interface aligned with the 250 kbps data rate. The half-duplex RS422/RS485 function means the link operates in one direction at a time, so system timing must coordinate transmit and receive periods. The 50 mV receiver hysteresis should be included in differential input threshold and noise-margin calculations. Board layout must accommodate the 8-SOIC surface-mount footprint with 0.154", 3.90 mm Width, and the -40°C to 85°C operating range should be considered during thermal and environmental review. Confirm that the selected protocol is RS422 or RS485 and that the system supply remains within the 3 V to 3.6 V range.
