DS36C280MX/NOPB

Drivers, Receivers, Transceivers Overview

The DS36C280MX/NOPB is a low-power CMOS RS-485 transceiver in an 8-pin SOIC package. It operates at +4.75V to +5.25V with a maximum supply current of 500 μA. The device supports up to 128 nodes on the bus and features a wide common mode range from −7V to +12V. Slew rate control allows edge rates between 100 ns and 3 μs via an external resistor. Propagation delays are typically 399 ns for the driver and 210 ns for the receiver.

Drivers, Receivers, Transceivers Feature Summary

• Adjustable slew rate control minimizes electromagnetic interference effects
• Built-in power-up/down glitch-free circuitry permits live insertion and displacement
• On-board thermal shutdown prevents damage during excessive power dissipation

Drivers, Receivers, Transceivers Applications

• Multipoint data transmission systems requiring EMI reduction
• Battery-powered or power-conscious industrial applications
• Systems requiring live transceiver insertion or displacement

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation, as ordering codes define package type and temperature range. Confirm that the component status matches project requirements, noting that this specific part number may be classified as obsolete by the manufacturer. Ensure compliance with RoHS standards and verify lead finish specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the DS36C280 when adjustable edge rates are required to reduce switching noise compared to fixed-rate devices. Choose this model over standard RS-485 transceivers if the application demands high node counts (up to 128) and low quiescent current. Verify that the operating temperature range aligns with the system environment, as commercial and industrial variants exist within the family.

Drivers, Receivers, Transceivers Part Context

This component belongs to the DS36C2xx series of differential bus transceivers manufactured by Texas Instruments. It shares architectural similarities with the DS36C278 and DS36C279 but distinguishes itself through integrated slew rate control capabilities. The device serves as a robust interface solution for multipoint communication networks requiring high reliability and low power consumption.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers include DS36C280M/NOPB and DS36C280TM/NOPB. These alternatives share identical electrical characteristics and pinouts but differ in package quantity or specific temperature ratings. Verify compatibility with existing board layouts and ensure the replacement meets the required operational temperature range.
