What are the key features of LTC2865IDE#PBF?
- Selectable 20 Mbps or 250 kbps data rate for flexible RS-485 bus configuration in a single device
- 60 V bus fault protection on driver and receiver pins guarding against industrial wiring faults and transients
- Separate logic supply input supporting 3.3 V and 5 V systems with full-duplex driver and enable controls
What is LTC2865IDE#PBF used for?
The LTC2865IDE#PBF is designed for industrial automation networks, motor drive control buses, and building management systems that require robust RS-485 or RS-422 communication over long cable runs in high-noise environments. Its 60 V fault protection makes it suitable for panel-wiring scenarios where mis-wired cables may apply damaging voltages to transceiver pins. Engineers also deploy it in multi-drop fieldbus backplanes and SCADA remote terminal units where the choice between 20 Mbps high-speed and 250 kbps low-power modes extends system flexibility.

Frequently Asked Questions
What data rates does LTC2865IDE#PBF support, and how does the rate selection affect power consumption?
The LTC2865IDE#PBF offers a selectable data rate of either 20 Mbps for high-speed data transfer or 250 kbps for low-power operation on the same RS-485 bus. Switching to 250 kbps reduces drive current and slew rate, lowering electromagnetic emissions and supply current in battery-backed RTU and SCADA nodes where energy budget is constrained.
How much bus fault voltage can the LTC2865IDE#PBF withstand, and why is this important in industrial wiring?
The LTC2865IDE#PBF tolerates up to ±60 V on its bus pins without permanent damage. In industrial panel installations, mis-wired power conductors or ground faults can apply tens of volts to RS-485 lines. Standard transceivers typically survive only ±15 V to ±25 V, so the 60 V rating of the LTC2865IDE#PBF prevents costly field failures when sharing conduits with power wiring.
Can LTC2865IDE#PBF interface directly with both 3.3 V and 5 V microcontrollers without level shifters?
Yes. The LTC2865IDE#PBF features a dedicated logic supply pin (VL) that independently sets the driver input and receiver output logic levels. Connecting VL to 3.3 V configures the device for 3.3 V logic, while connecting VL to 5 V makes it compatible with 5 V MCUs. This eliminates external level-shift ICs and reduces BOM cost in mixed-voltage industrial controller boards.
In a multi-drop RS-485 network, how many nodes can share a bus with LTC2865IDE#PBF?
The LTC2865IDE#PBF presents a 1/8 unit load to the RS-485 bus, which allows up to 256 devices on a single segment under the standard RS-485 loading rule of 32 unit loads per driver. For a 20 Mbps link, stub length and cable termination with a 120-ohm resistor at each end remain the practical limits rather than receiver count, enabling large multi-drop networks in factory automation backbones.
