LTC2862IS8-1#TRPBF

Product Overview

The Analog Devices Inc. LTC2862IS8-1#TRPBF is a surface-mount RS422/RS485 transceiver implemented in an 8-SOIC package. The device provides a single driver and a single receiver for half-duplex differential serial communication, supporting a data rate of 20 Mbps. It operates from a 3 V to 5.5 V supply and has an operating temperature range of -40°C to 85°C. The 150 mV receiver hysteresis is a receiver characteristic for RS422 and RS485 applications.

Key Features

• RS422 and RS485 protocol support
• 1/1 driver/receiver configuration for half-duplex operation
• 20 Mbps data rate
• 3 V to 5.5 V supply voltage range
• -40°C to 85°C operating temperature range
• 150 mV receiver hysteresis
• 8-SOIC surface-mount package with 3.90 mm width

Applications

• Serial communication links that use RS422 or RS485 differential signaling
• Half-duplex data acquisition equipment that exchanges measurements over a serial interface
• 3 V to 5.5 V powered control systems that require 20 Mbps serial interface capability

Design & Procurement Notes

Design considerations should account for the 3 V to 5.5 V supply range and the -40°C to 85°C operating temperature range when selecting the power rail and board environment. The 8-SOIC surface-mount package requires an appropriate PCB footprint and solder pad layout. Because the transceiver is configured as a half-duplex 1/1 device, simultaneous transmit and receive operation is not supported, so the system must manage communication direction at the protocol level. The 150 mV receiver hysteresis and 20 Mbps data rate should be considered when evaluating differential signal margins and baud-rate requirements in RS422/RS485 links. The 3.90 mm package width and 8-SO device package should be confirmed against available board area.
