What are the key features of LTC2865IMSE#PBF?
- Selectable 20 Mbps / 250 kbps data rate modes enabling flexible RS-422/RS-485 system design from low-speed sensor buses to high-speed industrial networks
- ±60 V bus fault protection on driver and receiver pins guarding against cable shorts and overvoltage transients without external protection components
- Separate logic supply (VL) pin allowing 1.8 V to 5 V microcontroller I/O interfacing independent of the bus supply voltage
What is LTC2865IMSE#PBF used for?
LTC2865IMSE#PBF is designed for industrial RS-485 networks requiring both high-speed data acquisition at 20 Mbps and robust fault tolerance against ±60 V cable transients. It suits multi-drop sensor buses, motor drive command interfaces, and building automation controllers where long cable runs expose transceivers to high-voltage faults. The separate logic supply pin makes it directly compatible with 3.3 V or 1.8 V microcontrollers without level shifters.

Frequently Asked Questions
How does the ±60 V fault protection of LTC2865IMSE#PBF protect RS-485 bus nodes in industrial cable environments?
LTC2865IMSE#PBF withstands bus faults up to ±60 V on driver and receiver pins, well above the ±15 V limit of standard RS-485 transceivers. This eliminates the need for external TVS diodes on long cable runs of 100 m or more in factory automation, motor drives, and process control networks where cable cross-connections can inject dangerous voltages.
When should a designer select 20 Mbps versus 250 kbps mode on LTC2865IMSE#PBF?
Select 20 Mbps for high-throughput RS-422 point-to-point links such as camera data buses or high-speed encoder interfaces where latency below 50 ns per bit matters. Choose 250 kbps for multi-drop RS-485 networks with cable lengths up to 1200 m, where lower slew rate reduces EMI and reflections on unterminated or long industrial buses.
What logic supply voltage range does LTC2865IMSE#PBF support, and how does this benefit 3.3 V microcontroller designs?
The VL pin on LTC2865IMSE#PBF accepts 1.71 V to 5.5 V, allowing direct connection to 3.3 V or 1.8 V microcontroller I/O without external level shifters. This single-chip solution reduces BOM cost and PCB area compared to two-chip alternatives using a standard 5 V transceiver plus a separate level-translation IC.
How many LTC2865IMSE#PBF devices can be connected on a single RS-485 bus, and what termination is recommended?
RS-485 bus configurations typically support up to 32 unit-load nodes. LTC2865IMSE#PBF presents 1/8 unit load, allowing up to 256 transceivers on a single bus. A 120 Ω termination resistor at each cable end is recommended for data rates of 1 Mbps or above to minimize reflections and maintain signal integrity across cable runs exceeding 10 m.
