- Data rate up to 250 kbps enabling reliable communication over long cable runs in industrial automation
- Differential Schmitt trigger receiver inputs providing excellent noise immunity on electrically noisy factory-floor bus wiring
- 5 V single-supply operation simplifying power design in PLC, sensor, and embedded communication modules
- Compact 8-pin MSOP package (05-08-1660) minimizing PCB footprint in dense industrial interface boards
Applications
The LTC2856CMS8-2#TRPBF is used in industrial automation, building control, and process instrumentation networks where RS-485 multi-drop communication over cable runs of hundreds of meters is required. It is well suited for PLC I/O modules, smart sensors, and motor drive command interfaces that need half-duplex 2-wire RS-485 at 250 kbps on a 5 V supply. Energy meter networks, HVAC controllers, and lighting control systems also rely on its Schmitt trigger noise immunity to maintain data integrity in electrically harsh environments.

Frequently Asked Questions
What maximum data rate does the LTC2856CMS8-2#TRPBF support, and over what cable distance is RS-485 communication reliable at that rate?
The LTC2856CMS8-2#TRPBF supports data rates up to 250 kbps. At 250 kbps the RS-485 standard allows cable runs of up to approximately 300 meters with standard 120 Ω termination, making it suitable for factory-floor sensor buses, building automation backbones, and process control networks where devices are widely distributed.
What input architecture does the LTC2856CMS8-2#TRPBF receiver use, and how does it benefit noisy industrial environments?
The LTC2856CMS8-2#TRPBF uses differential Schmitt trigger inputs on its receiver, which provide hysteresis to suppress noise spikes on the RS-485 bus wire. In industrial environments where variable-frequency drives, contactors, and solenoids generate EMI, the Schmitt trigger prevents false transitions from noise bursts, improving communication reliability on cables running alongside power wiring.
Which interface standards does the LTC2856CMS8-2#TRPBF comply with, and can it interoperate with RS-422 devices?
The LTC2856CMS8-2#TRPBF is compliant with EIA-485-A, TIA-485-A, and EIA-422, allowing it to communicate with any RS-485 or RS-422 transceiver on the bus. RS-422 devices are point-to-point or broadcast, and the LTC2856CMS8-2#TRPBF can transmit at EIA-422 driver voltage levels while receiving from RS-422 line drivers, giving flexibility in mixed-protocol industrial networks.
For a PLC I/O module design, what supply voltage does the LTC2856CMS8-2#TRPBF require, and what package does it use?
The LTC2856CMS8-2#TRPBF operates from a single 5 V supply, which is the standard logic rail in most PLC I/O and industrial microcontroller modules. It comes in an 8-pin MSOP (S-PDSO-G8) package with a small footprint, allowing multiple transceivers to be placed on a dense I/O card alongside isolation barriers and protection components without consuming excessive board area.
