SP3483EN-L

Drivers, Receivers, Transceivers Overview

The SP3483EN-L is a +3.3V low-power half-duplex RS-485 transceiver manufactured by MaxLinear, Inc. It supports data rates up to 250 kbps and operates from a single +3.3V supply while remaining interoperable with +5.0V logic. The device features a -7V to +12V common-mode input voltage range and allows up to 32 transceivers on the serial bus. Key electrical characteristics include driver output short-circuit protection and slew rate limiting for reduced EMI. It is pin-to-pin compatible with industry standards such as the 75176.

Drivers, Receivers, Transceivers Feature Summary

• Slew rate limited driver design minimizes electromagnetic interference (EMI) during signal transitions.
• Integrated low power shutdown mode reduces system energy consumption when the device is idle.
• Robust protection mechanisms include driver output short-circuit protection against fault conditions.

Drivers, Receivers, Transceivers Applications

• Industrial automation systems requiring reliable serial communication over long distances.
• Building automation networks connecting sensors and control units.
• Data acquisition systems utilizing RS-485 multi-drop configurations.

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin carefully, as this component was originally developed by Exar Corporation before its acquisition by MaxLinear. Confirm that the specific package variant matches the required PCB footprint. Ensure the datasheet version aligns with the current production status to avoid discrepancies in electrical specifications or pin definitions during the sourcing process.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications prioritizing low power consumption and EMI reduction over high-speed data transmission. It is suitable for systems operating at speeds up to 250 kbps where interoperability with +5V logic is necessary despite a 3.3V supply. Consider alternative models if data rates exceeding 250 kbps are required for the specific project constraints.

Drivers, Receivers, Transceivers Part Context

The SP3483EN-L belongs to the SP348x family of low-power RS-485 transceivers. This series is designed to provide robust communication capabilities in noisy environments while maintaining low energy usage. The device maintains compatibility with standard industrial pinouts, facilitating easy integration into existing designs without significant hardware modifications.

Drivers, Receivers, Transceivers Replacement Considerations

The SP3483EN-L is pin-to-pin compatible with the Exar SP483 device. It also shares compatibility with popular industry standards like the 75176. Verify functional equivalence regarding slew rate limitations and shutdown modes when substituting with other generic RS-485 transceivers.
