LTC2861CGN#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2861CGN#TRPBF is a full-duplex RS-485/RS-422 transceiver operating on a 5V supply. It features a logic-selectable 120Ω termination resistor and supports up to 256 nodes per bus with one-eighth unit load input impedance. The device offers a maximum data rate of 20Mbps, with an optional low-EMI mode limited to 250kbps via the SLO pin. It includes failsafe receiver operation, current-limited drivers, and thermal shutdown protection. The component operates within a temperature range of 0°C to 70°C and is housed in a 16-lead SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated switchable 120Ω termination resistor for optimized signal fidelity
• Logic-selectable low-EMI mode to reduce high-frequency emissions
• Guaranteed failsafe receiver output under floating or shorted input conditions
• High input impedance supporting up to 256 nodes on the bus

Drivers, Receivers, Transceivers Applications

• Level translator applications
• Backplane communication systems
• Multi-node RS-485 networks requiring end termination control

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging. Confirm the CGN suffix corresponds to the commercial temperature grade (0°C to 70°C) and SSOP-16 package. Ensure compatibility with standard 5V logic levels before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model for full-duplex RS-485/RS-422 applications requiring integrated line termination. Choose the CGN variant for commercial temperature environments. Consider the H-grade or I-grade variants if extended temperature ranges are required. Verify that the 5V supply voltage aligns with system power rails.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2859/LTC2861 family of low-power 20Mbps transceivers. Unlike the half-duplex LTC2859, the LTC2861 provides separate driver outputs for full-duplex communication. Both share identical receiver characteristics, including the switchable termination and ESD protection features.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2859CGN#TRPBF serves as a direct functional substitute for half-duplex implementations. For full-duplex requirements, verify compatibility with other members of the LTC28xx series offering similar termination and ESD specifications.
