Applications
The LTC2850HMS8 is designed for RS-485 multi-drop networks in industrial automation, SCADA systems, and building management controllers where noise-immune differential communication over cable lengths up to 1200 meters is required. Its 20 Mbps throughput supports high-speed sensor data aggregation and real-time control loops in factory floor networks. The 3.3 V supply compatibility also makes it suitable for interfacing modern microcontrollers in IoT gateways and remote terminal units directly without level translation.

Frequently Asked Questions
At what maximum data rate can the LTC2850HMS8 transmit RS-485 signals, and how far can the cable run at that speed?
The LTC2850HMS8 supports up to 20 Mbps half-duplex RS-485 transmission, suitable for short-distance high-speed links of up to approximately 10 meters. For longer distances up to 1200 meters, the data rate must be reduced to around 100 kbps to compensate for cable capacitance and maintain signal integrity per EIA-485-A specifications.
How does the differential Schmitt trigger input of the LTC2850HMS8 improve reliability on noisy industrial networks?
The differential Schmitt trigger provides hysteresis on the receiver input, rejecting noise spikes and voltage glitches that would cause false triggering on a standard comparator receiver. On a factory floor where 24 V relay coils and variable-frequency drives generate conducted noise, this feature ensures valid data detection even when the RS-485 differential voltage dips below the standard 200 mV threshold momentarily.
When upgrading a 5 V RS-485 network node to a 3.3 V microcontroller, does the LTC2850HMS8 require a level shifter?
No. The LTC2850HMS8 operates from a 3.3 V supply and its logic I/O pins are directly compatible with 3.3 V microcontrollers, eliminating the need for separate level translation. This simplifies the hardware design for RS-485 gateway boards transitioning from legacy 5 V systems to modern 32-bit MCUs running at 3.3 V logic levels.
