LTC1480CN8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1480CN8#PBF is an ultralow power differential line transceiver providing full RS485 compatibility from a single 3.3V supply. It supports data rates up to 2.5Mb/s with a common mode range of –7V to 12V. The device operates within the commercial temperature range of 0°C to 70°C and draws 300µA typical quiescent current when enabled without load, reducing to 1µA in shutdown. It features thermal shutdown protection, glitch-free outputs for live insertion, and fail-safe receiver inputs.

Drivers, Receivers, Transceivers Feature Summary

• Operates from a single 3.3V supply while maintaining full RS485 compatibility
• Extended common mode range supporting ±7V ground differences between devices
• Thermal shutdown circuit prevents excessive power dissipation during bus contention
• Glitch-free driver outputs permit safe live insertion or removal of transceivers

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CN8 indicates the commercial temperature grade (0°C to 70°C) and PDIP-8 package configuration. Confirm the #PBF designation ensures lead-free compliance. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity before integration into designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for systems requiring low power consumption on a 3.3V rail. Ensure the application stays within the commercial temperature limits; use the IN8 variant for extended industrial ranges. Verify that the 2.5Mb/s maximum data rate meets system timing requirements and that the 12kΩ input resistance suits the bus topology.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC1480 family of ultralow power RS485 transceivers. It serves as a pin-compatible alternative to the LTC485 but operates at lower voltages. The series includes variants like the LTC1481 and LTC1483, which offer different power profiles or EMI characteristics while maintaining similar interface standards.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC1480IN8#PBF provides identical functionality but covers the extended industrial temperature range (-40°C to 85°C). Other pin-compatible options include the LTC485, though it requires a 5V supply.
