LTC2856IMS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2856IMS8-2#TRPBF is a low-power, half-duplex RS485/RS422 transceiver housed in an 8-lead MSOP package. It operates on a single 5V supply with a maximum data rate of 250kbps to minimize electromagnetic interference. The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, supporting up to 256 nodes per bus. It includes current-limited drivers and thermal shutdown protection against excessive power dissipation. Enhanced ESD protection withstands ±15kV (HBM) without latchup. The part guarantees failsafe receiver operation over the entire common mode range and offers glitch-free driver outputs during power transitions.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited driver outputs for reduced high-frequency EMI emissions
• High input impedance receiver supporting extensive network node counts
• Integrated thermal shutdown and current limiting for fault protection

Drivers, Receivers, Transceivers Applications

• Low EMI industrial communication networks
• Multipoint RS485 bus systems
• Backplane transceivers requiring noise reduction

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing components. Confirm the IMS8 designation matches the required 8-lead MSOP physical footprint for PCB layout compatibility. Ensure the I-grade temperature rating aligns with the operational environment requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model specifically for applications prioritizing low electromagnetic interference over high-speed data throughput. The 250kbps slew-rate limited variant is distinct from the 20Mbps versions within the same family. Verify that the half-duplex configuration meets the system's bidirectional communication needs compared to full-duplex alternatives.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2856 series of rugged RS485/RS422 transceivers designed for harsh electrical environments. It shares core protection features with the LTC2857 and LTC2858 families but differs in duplex capability and pin count. The series emphasizes robust fault tolerance and low power consumption for battery-operated or thermally constrained devices.
