Overview

The LTC2862CS8-1#PBF is a single-channel, half-duplex RS-422/RS-485 transceiver in an 8-SOIC package. It accepts 3 V to 5.5 V supplies and supports data rates up to 20 Mbps with a receiver hysteresis of 150 mV. The device is intended for low-power, robust serial communications in compact surface-mount applications. Operating temperature listed is 0 to 70 C and it is supplied in an 8-SOIC (3.90 mm width) package.

Why Choose This Part

The LTC2862 supports a wide supply range (3.0 V to 5.5 V) so it can be used directly with 3.3 V or 5 V logic systems. Its 20 Mbps data-rate capability covers high-speed serial links while the 150 mV receiver hysteresis improves noise immunity on long differential runs. The 8-SOIC surface-mount package keeps PCB footprint small for space-constrained embedded designs, and the part is specified for commercial temperature operation for standard deployments.

Applications

Industrial fieldbus nodes
Use as the serial transceiver interface between sensors/actuators and PLCs on RS-485 networks.
Building automation and BAS networks
Connect HVAC, lighting, and access-control controllers over long-distance differential pairs.
Embedded gateway or protocol converters
Interface microcontroller UARTs to RS-485 trunks in protocol bridge or gateway devices.
Motor drives and factory automation
Provide reliable half-duplex communications in electrically noisy environments when paired with proper termination and protection.
Data acquisition and telemetry
Link remote sensor clusters to a central collector over differential twisted-pair wiring.

Getting Started

There is no dedicated IDE for RS-485 transceivers; you test this device by wiring it into your MCU UART or an evaluation board and exercising differential A/B lines. Start with a single-ended UART microcontroller (3.3 V or 5 V) and a short twisted-pair run, add the recommended termination resistor and fail-safe biasing, and verify signal levels with a scope. For development, use a breakout or evaluation board when available, and include proper decoupling, transient suppression (TVS) or common-mode choke if your application is exposed to large surges or long cable runs.
