What are the key features of DS36C279M?
- EIA-422-B and EIA-485 compliant differential transceiver with Schmitt-trigger input for robust noise rejection over long cable runs
- Single 1-bit driver/receiver architecture with differential output enabling point-to-point and multi-drop RS-485 bus communication
- 8-pin SOIC (PDSO-G8) package with 2 µA maximum high-level input current enabling low-power bus interface designs in industrial control networks
What is DS36C279M used for?
The DS36C279M is designed for industrial RS-422 and RS-485 serial communication networks connecting PLCs, sensors, and actuators over distances of hundreds of meters in electrically noisy factory environments. Its differential Schmitt-trigger input provides immunity to common-mode interference from motor drives and switching supplies that share cable trays with the communication wiring. The device is also suited for process-control instrumentation, SCADA terminal wiring, and multi-drop half-duplex RS-485 bus links where reliable differential data transmission at low quiescent current is critical.

Frequently Asked Questions
Which serial bus standards does the DS36C279M support, and over what cable distances can it operate reliably?
The DS36C279M is compliant with EIA-422-B, TIA-422-B, and EIA-485 differential signaling standards, which specify reliable operation over cable runs of up to 1,200 meters at data rates below 100 kbps, or shorter distances at higher speeds. This makes it suitable for fieldbus and SCADA wiring in large industrial facilities where single-ended UART signals would be corrupted by ground-potential differences between equipment.
How does the differential Schmitt-trigger input of DS36C279M improve noise immunity on an RS-485 industrial bus?
The DS36C279M uses a differential Schmitt-trigger on the receiver input, which applies hysteresis to the decision threshold so small noise spikes riding on the differential pair do not cause false bit transitions. In environments with variable-frequency motor drives and inductive switching loads generating common-mode noise above 1 V, the differential architecture cancels the coupled interference, and the Schmitt trigger suppresses residual edge noise, maintaining a clean 2 µA input threshold.
For a factory PLC network, how does the DS36C279M's 1-bit driver architecture fit multi-drop RS-485 topologies?
The DS36C279M's 1-bit driver with differential output is fully compatible with multi-drop RS-485 half-duplex bus topologies where multiple nodes share a single twisted-pair. Each node's driver can be disabled to high-impedance state when not transmitting, preventing bus contention across the 1,200-meter segment. This matches the electrical requirements of PLC I/O expansion, remote sensor polling, and MODBUS RTU protocols common in process automation.
What package does DS36C279M use, and how does the lead-free classification affect sourcing for new industrial designs?
The DS36C279M uses an 8-pin SOIC (R-PDSO-G8) package with a JESD-609 e0 code indicating a non-lead-free finish, which means it may not comply with RoHS 2011/65/EU requirements for new EU market designs. Procurement engineers specifying DS36C279M for new industrial control boards should verify the exemption status or evaluate a lead-free compatible successor part that carries an e3 or e4 JESD-609 code before committing to a high-volume bill of materials.
