SP3078EEN-L/TR

Drivers, Receivers, Transceivers Overview

The SP3078EEN-L/TR is a MaxLinear RS-422/RS-485 interface IC transceiver housed in an SOIC-8 package. It supports half-duplex communication with a data rate of 16 Mb/s. The device operates on a supply voltage ranging from 3 V to 3.6 V, typically at 3.3 V, with a quiescent current of 800 uA. It features differential outputs capable of delivering 250 mA and provides ±15 kV ESD protection. The component functions within a temperature range of -40°C to +125°C, with propagation delays specified at 50 ns and 75 ns.

Drivers, Receivers, Transceivers Feature Summary

• Provides robust electrostatic discharge protection rated at ±15 kV for enhanced signal integrity in noisy environments.
• Supports high-speed data transmission up to 16 Mb/s over differential lines for efficient half-duplex communication.
• Operates reliably across an extended industrial temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring reliable serial communication.
• Building automation networks utilizing RS-485 bus topologies.
• Metering infrastructure for utility data collection applications.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix L/TR against official MaxLinear documentation to confirm tape-and-reel packaging specifications. Ensure the SOIC-8 footprint matches the target PCB design constraints. Cross-reference the RoHS status directly with the manufacturer's latest compliance declarations rather than relying solely on distributor summaries.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16 Mb/s data rate is required alongside extended temperature capabilities. Compare against the SP3072EMN-L/TR if lower speed but similar form factor is acceptable. Verify that the 3.3 V supply voltage aligns with the system power architecture before finalizing the bill of materials.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3078E series of 3.3V RS-485/RS-422 transceivers manufactured by MaxLinear. It shares functional similarities with other devices in the family but is distinguished by its specific 16 Mb/s speed rating and industrial temperature grade. The SOIC-8 package offers a compact solution for space-constrained designs.

Drivers, Receivers, Transceivers Replacement Considerations

SP3078EMN-L/TR is a verified alternative within the same series offering identical electrical characteristics in a different package variant.
