MAX13081EESA+

Product Overview

The MAX13081EESA+ from Analog Devices Inc./Maxim Integrated is a surface-mount transceiver for balanced serial communication using RS422 and RS485 protocols. It contains one driver and one receiver in a full-duplex configuration, supports a 250kbps data rate, and operates from a 4.5V to 5.5V supply. The 8-SOIC package is a surface-mount option, and the operating temperature range is -40°C to 85°C.

Key Features

• Single transceiver with 1 driver and 1 receiver
• Supports RS422 and RS485 protocols in full-duplex mode
• 250kbps data rate
• 100 mV receiver hysteresis
• 4.5V to 5.5V supply voltage range
• -40°C to 85°C operating temperature range
• Surface-mount 8-SOIC package, 0.154 inch / 3.90 mm width

Applications

• RS422 or RS485 serial data links
• Full-duplex communication between a controller and remote serial device
• 5V-powered embedded control hardware
• Instrumentation interface boards using balanced serial communication

Design & Procurement Notes

Design should confirm that the system supply remains within 4.5V to 5.5V and that ambient conditions are within -40°C to 85°C. The full-duplex RS422/RS485 configuration requires separate transmit and receive signal paths, so pin assignment and external signal conditioning should be checked for the selected protocol mode. The 100 mV receiver hysteresis can be considered during threshold and noise-margin review. The 250kbps data rate should be included in link timing and protocol planning. The 1/1 driver/receiver ratio means the part provides a single transmit channel and a single receive channel, which should be matched to the system topology. For PCB layout, use the 8-SOIC surface-mount land pattern and account for the 3.90 mm body width in board spacing and assembly constraints.
