ISL83485IBZ

Product Overview

The ISL83485IBZ from Renesas Electronics Corporation is a surface-mount transceiver for differential serial communication using RS422 and RS485. The device integrates one driver and one receiver in a half-duplex configuration, allowing a single bidirectional data path to be managed within the 3 V to 3.6 V supply range. Its package is an 8-SOIC with a 0.154 in, 3.90 mm width, for surface-mount assemblies. The operating temperature range is -40°C to 85°C, the receiver hysteresis is 50 mV, and the data rate is 10 Mbps.

Key Features

• Half-duplex transceiver with one driver and one receiver
• RS422 and RS485 protocol
• Data rate of 10 Mbps
• Supply voltage range of 3 V to 3.6 V
• Receiver hysteresis of 50 mV
• Operating temperature range of -40°C to 85°C
• 8-SOIC surface-mount package with 0.154 in, 3.90 mm width

Applications

• Differential serial data links using RS422 or RS485
• Half-duplex communication between logic circuits and bus lines
• Low-voltage 3 V to 3.6 V system interfaces in surface-mount assemblies
• Embedded control boards operating within -40°C to 85°C ambient range

Design & Procurement Notes

The ISL83485IBZ should be considered when a system requires a half-duplex differential transceiver operating from a 3 V to 3.6 V supply. Designers should verify that the host interface and data path are compatible with the 10 Mbps data rate and 50 mV receiver hysteresis. The 8-SOIC package, with a 0.154 in, 3.90 mm body width, affects land pattern, spacing, and surface-mount layout. The -40°C to 85°C operating temperature range should be checked against the expected ambient conditions. Procurement and PCB planning should account for the single driver and single receiver arrangement for half-duplex operation.
