MAX3088EESA+T

Product Overview

The MAX3088EESA+T from Analog Devices Inc./Maxim Integrated is a surface-mount interface transceiver intended for half-duplex serial communication over RS422 and RS485 buses. The device combines one driver and one receiver in an 8-SOIC package and operates from a 4.75 V to 5.25 V supply. Its specified data rate is 10 Mbps, and its receiver input hysteresis is 100 mV. The part is characterized for operation from -40°C to 85°C, supporting board-level designs that require a compact 8-SOIC footprint, a single 5 V supply, and conventional RS422/RS485 physical-layer signaling.

Key Features

• Half-duplex transceiver with one driver and one receiver
• Supports RS422 and RS485 protocols
• Specified data rate of 10 Mbps
• Receiver hysteresis of 100 mV
• 5 V supply operation from 4.75 V to 5.25 V
• Operating temperature range of -40°C to 85°C
• Surface-mount 8-SOIC package with 0.154 in, 3.90 mm width

Applications

• Half-duplex serial links between controllers and remote I/O modules
• RS422 or RS485 bus segments for data collection devices
• Serial communication between embedded host processors and field instruments

Design & Procurement Notes

Designers should verify that the host system provides a 4.75 V to 5.25 V supply and that the board layout supports the 8-SOIC footprint and surface-mount assembly. The 10 Mbps data rate and 100 mV receiver hysteresis are relevant to bus topology, signal integrity, and noise margin planning. Because the device is a half-duplex 1/1 transceiver, protocol-level control must manage direction switching between transmit and receive states. The -40°C to 85°C operating range should be considered in thermal and enclosure design, while the 8-SOIC package width of 0.154 in, 3.90 mm affects pad spacing and routing.
