Key Features
- Full-duplex RS-485/RS-422 transceiver compliant with EIA-485-A and EIA-422 standards
- Up to 250 kbps data rate with differential Schmitt-trigger receiver inputs for noise immunity
- 5 V single-supply operation with driver and receiver enable controls for half or full duplex configurations
- 10-pin MSOP package enabling compact placement near connectors on industrial PCBs
- Robust failsafe receiver output when bus lines are open, shorted, or terminated
Applications
Designed for industrial serial communication links such as SCADA networks, factory automation fieldbus segments, and building automation controllers where RS-485's differential signaling provides noise immunity over cable runs up to 1200 m. The LTC2858IMS-2#TRPBF suits RS-422 point-to-point full-duplex links in motion control, medical equipment, and test instruments where the 250 kbps rate satisfies most sensor and actuator polling cycles. Its compact 10-pin MSOP package fits tight PCB layouts near terminal block connectors in DIN-rail industrial modules.

Frequently Asked Questions
At what maximum data rate does the LTC2858IMS-2#TRPBF operate on an RS-485 bus, and how far can the cable run?
The LTC2858IMS-2#TRPBF supports up to 250 kbps over an RS-485 differential bus. At this data rate, cable runs of up to 1200 m are achievable with proper 120 Ohm termination at each end, meeting the requirements of most industrial SCADA and process control installations.
Does the LTC2858IMS-2#TRPBF support RS-422 full-duplex wiring in addition to RS-485 half-duplex configurations?
Yes. The device is compliant with both EIA-485-A (RS-485) and EIA-422 standards, so it can be wired as a 4-wire RS-422 full-duplex link using separate transmit and receive pairs, or as a 2-wire RS-485 half-duplex network with the driver and receiver enable pins controlling bus access.
How does the differential Schmitt-trigger input of the LTC2858IMS-2#TRPBF improve receiver performance in electrically noisy environments?
The receiver uses a differential Schmitt-trigger input, which provides input hysteresis typically of 50 mV or more above the standard RS-485 minimum. This rejects fast transients and common-mode noise spikes common on long cable runs in motor drives and switching power supply environments, reducing false triggering and improving link reliability.
What is the physical package size of the LTC2858IMS-2#TRPBF and how does it affect PCB layout near an RS-485 connector?
The 10-pin MSOP package has a 3 x 3 mm body footprint, significantly smaller than SOIC alternatives. This allows the transceiver to be placed within 5 mm to 10 mm of the RS-485 connector pads, minimizing stub length on the differential pair and reducing reflected wave distortion at 250 kbps.
