LTC2862ACS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862ACS8-2#PBF is a low-power, half-duplex RS485/RS422 transceiver operating on a 3V to 5.5V supply. It supports a maximum data rate of 250kbps with slew-rate limiting for reduced EMI. The device features ±60V overvoltage fault protection on interface pins and Level 4 IEC ESD protection. It operates within a commercial temperature range of 0°C to 70°C in an 8-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V fault protection on A and B pins during all operational modes
• Features Level 4 IEC ESD and EFT protection on interface pins
• Includes extended common mode input range from -25V to +25V
• Offers guaranteed failsafe receiver operation with enhanced noise immunity

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Building automation and security systems
• HVAC equipment
• Medical equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to 70°C) and 'S8' denotes the SOIC-8 package. Confirm the '-2' designation corresponds to the 250kbps slew-limited variant rather than the high-speed option. Ensure compatibility with system voltage requirements between 3V and 5.5V.

Drivers, Receivers, Transceivers Selection Notes

Select this component when robust fault tolerance against large ground loop voltages is required. The 250kbps data rate makes it suitable for applications prioritizing electromagnetic interference reduction over high throughput. Verify that the commercial temperature range meets environmental constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862A family, which improves upon the original LTC2862 by adding higher ESD ratings and enhanced failsafe functions. The '-2' suffix distinguishes it as the low-speed, low-EMI variant compared to the '-1' high-speed version. It maintains pin compatibility with legacy parts like the LT1785.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2862AIS8-2#PBF: Identical electrical function but rated for industrial temperature (-40°C to 85°C). LTC2862AHS8-2#PBF: Identical electrical function but rated for automotive/high temperature (-40°C to 125°C).
