SP1485ECN-L

Drivers, Receivers, Transceivers Overview

The SP1485ECN-L is a half-duplex RS-485 transceiver manufactured by MaxLinear, Inc. It supports data rates up to 20 Mb/s and operates within a supply voltage range of 4.75 V to 5.25 V. The device features one driver and one receiver in an SOIC-8 package. It functions reliably across an extended temperature range from -40°C to +85°C. Key electrical specifications include a quiescent current of 900 uA, output currents of 250 mA, and ESD protection rated at +/-15 kV. Propagation delays are specified at 20 ns and 25 ns.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed data transmission up to 20 Mb/s for RS-485 applications
• Provides robust electrostatic discharge protection rated at +/-15 kV
• Operates with low power consumption suitable for battery-powered systems

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building automation and security systems
• Data acquisition systems requiring long-distance communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' against official MaxLinear documentation to confirm lead-free compliance and RoHS status. Ensure the ordering information matches the exact package type and temperature grade required for the target application environment before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5V supply is available and high-speed data rates near 20 Mb/s are necessary. Compare against the SP3485 series if a 3.3V operating voltage is required instead. Verify that the half-duplex architecture aligns with the system's communication protocol requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP1485E series of RS-422/RS-485 interface ICs. It shares functional similarities with other MaxLinear transceivers but is distinct due to its specific 20 Mb/s speed rating and 5V operation. It serves as a solution for reliable differential bus communication in noisy environments.
