LTC2862IS8-1#PBF

Product Overview

Analog Devices Inc. LTC2862IS8-1#PBF is a half-duplex transceiver intended for RS422 and RS485 serial communication links. The device combines one driver and one receiver in an 8-SOIC surface-mount package, with a package width of 0.154 inch, or 3.90 mm. It operates from a 3 V to 5.5 V supply and is specified for an ambient temperature range of -40°C to 85°C. The transceiver supports a 20 Mbps data rate and provides 150 mV of receiver hysteresis, characteristics relevant to differential bus interfaces where noise immunity and defined duplex operation are required.

Key Features

• Half-duplex RS422 and RS485 transceiver with one driver and one receiver.
• 20 Mbps data rate for differential serial communication.
• 150 mV receiver hysteresis.
• 3 V to 5.5 V supply voltage range.
• Operating temperature range of -40°C to 85°C.
• 8-SOIC surface-mount package, 0.154 inch, 3.90 mm width.

Applications

• RS485 half-duplex differential bus links for serial data exchange.
• RS422 differential serial transmission and reception in compact interface sections.
• Surface-mount communication hardware operating from 3 V to 5.5 V supplies.

Design & Procurement Notes

When selecting LTC2862IS8-1#PBF, confirm that the board layout provides an 8-SOIC footprint compatible with 0.154 inch, 3.90 mm width, and surface-mount assembly. The supply rail should remain within 3 V to 5.5 V, and the expected ambient environment should remain within -40°C to 85°C. Because the device is a half-duplex 1/1 transceiver, system architecture should account for one driver and one receiver path rather than simultaneous full-duplex operation. The specified 20 Mbps data rate and 150 mV receiver hysteresis should be matched to the bus topology, signal integrity, and noise margin requirements of the design.
