LTC1480IS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1480IS8#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 an extended common mode range of –7V to 12V. Typical quiescent current is 300µA when operating and drops to 1µA in shutdown mode. The device features thermal shutdown protection, glitch-free driver outputs for live insertion, and receiver fail-safe functionality. It operates within the commercial temperature range (0°C to 70°C) and is housed in an 8-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Operates from a single 3.3V supply while maintaining full RS485 compatibility
• Extended common mode range supporting ±7V ground difference between devices
• Thermal shutdown circuit prevents excessive power dissipation during bus contention
• Receiver fail-safe ensures high output state when inputs are left open

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 #PBF indicates lead-free compliance and standard tube packaging. Confirm the IS8 designation corresponds to the industrial temperature grade and SOIC package style. Ensure the component matches the manufacturer's official datasheet specifications before integration into designs requiring strict environmental or electrical tolerances.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption from a 3.3V rail. It is suitable for systems needing extended common mode voltage tolerance and robust fault protection. Compare against the LTC485 for pin compatibility if migrating from 5V systems. Verify that the commercial temperature range meets the operational environment requirements.

Drivers, Receivers, Transceivers Part Context

The LTC1480 series includes variants like the LTC1480IN8 for through-hole DIP packaging and the LTC1480CS8 for commercial temperature ranges. The IS8 variant specifically denotes the industrial temperature extension and surface-mount SOIC form factor. This part belongs to Analog Devices' ultralow power interface IC family designed for efficient serial communication.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is explicitly noted as pin-compatible. Other related parts include the LTC1481, LTC1483, and LTC1487 for different power or EMI characteristics.
