LTC2862AIS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862AIS8-2#TRPBF is a low-power, half-duplex RS-485/RS-422 transceiver operating on a 3V to 5.5V supply. It supports a maximum data rate of 250kbps with slew-rate limiting for low EMI. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides Level 4 IEC ESD and EFT protection alongside ±40kV HBM ratings. The component operates within an ambient temperature range of -40°C to +85°C and is housed in an 8-lead (150mil) Plastic SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on A and B pins across all operational states
• Slew-rate limited transmission at 250kbps to minimize electromagnetic interference
• Extended common mode input range supporting voltages from -25V to +25V
• Guaranteed failsafe receiver operation ensuring logic high output during idle or open bus conditions

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA) networks
• Industrial control and instrumentation systems
• Building automation and security infrastructure
• HVAC system communication links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube packaging when sourcing components. Confirm the 'I' grade designation matches the required -40°C to +85°C operating temperature range for the target environment. Ensure the ordering information aligns with the 8-lead SOIC package format specified in the manufacturer documentation.

Drivers, Receivers, Transceivers Selection Notes

Select this variant specifically for applications requiring low EMI characteristics due to its 250kbps slew-rate limited driver. The 'I' grade ensures suitability for industrial environments requiring extended temperature coverage compared to commercial grades. Verify that the half-duplex configuration meets the bidirectional communication requirements of the network topology.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862A family, which includes variants optimized for different speeds and temperature ranges. The '-2' suffix designates the 250kbps low EMI option, distinct from the '-1' variant capable of 20Mbps. The '#TRPBF' suffix confirms lead-free tape and reel availability for automated assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with the standard LTC2862 and LT1785 devices. Designers should verify that the replacement component maintains the same ±60V fault protection and ESD specifications to ensure circuit robustness remains unchanged.
