LTC1480IN8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1480IN8#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. The device operates within the commercial temperature range (0°C to 70°C) and features typical quiescent currents of 300µA when active and 1µA in shutdown. Electrical specifications include a maximum supply voltage of 7V, driver propagation delays of 50ns typical, and thermal shutdown protection. It is housed in an 8-lead PDIP package.

Drivers, Receivers, Transceivers Feature Summary

• Operates from a single 3.3V supply while maintaining full RS485 compatibility
• Features extended common mode range supporting ±7V ground differences between devices
• Includes thermal shutdown circuitry to prevent excessive power dissipation during bus contention or faults
• Provides glitch-free driver outputs to permit live insertion or removal of the transceiver

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 confirm the N8 designation corresponds to the 8-lead PDIP package. Ensure the component meets the required commercial temperature range specifications for the intended environment. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and current production status before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low power consumption from a 3.3V source. It is suitable for applications needing extended common mode voltage tolerance and thermal protection. Consider the PDIP package constraints for through-hole mounting requirements. Verify that the 2.5Mb/s data rate and propagation delay characteristics align with system timing requirements.

Drivers, Receivers, Transceivers Part Context

The LTC1480 belongs to the Ultralow Power RS485 Transceiver family from Analog Devices. It serves as a low-power alternative to traditional CMOS drivers by incorporating Schottky diodes to prevent latch-up and handle high common mode voltages. The IN8 variant specifically denotes the industrial/commercial grade version in a PDIP package, distinct from the SOIC S8 package options available in the series.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet lists the LTC485 as pin-compatible. Other related parts include the LTC1481, LTC1483, LTC1485, and LTC1487, which offer variations in speed, EMI characteristics, and input impedance.
