LTC1480CS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1480CS8#PBF is an ultralow power differential line transceiver providing full RS485 compatibility while operating from a single 3.3V supply. It supports data transmission rates up to 2.5Mb/s and features an extended common mode range of –7V to 12V. The device draws a typical quiescent current of 300µA during operation, with a maximum of 600µA when the driver is enabled without load. In shutdown mode, the supply current drops to 1µA. It includes thermal shutdown protection and glitch-free driver outputs for live insertion applications.

Drivers, Receivers, Transceivers Feature Summary

• Operates from a single 3.3V supply with true RS485 compatibility
• Features extended common mode range from -7V to 12V
• Includes thermal shutdown protection against excessive power dissipation
• Provides glitch-free driver outputs to permit live insertion or removal

Drivers, Receivers, Transceivers Applications

• Battery-powered RS485/RS422 applications
• Low power RS485/RS422 transceivers
• Level translator circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance and standard tube packaging. Confirm the S8 package variant matches the required surface-mount footprint. Ensure the component grade aligns with the intended commercial temperature range specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low power consumption from a 3.3V rail. It is suitable for half-duplex communication where extended common mode voltage tolerance is necessary. Consider the 2.5Mb/s speed limit and 8-pin SOIC package constraints for board layout.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1480 family of ultralow power RS485 transceivers. It is pin-compatible with the older LTC485 model but optimized for 3.3V operation. The series focuses on minimizing power usage in industrial communication networks while maintaining robust signal integrity.

Drivers, Receivers, Transceivers Replacement Considerations

LTC1481CS8#PBF: Offers similar functionality with potentially lower power characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
