LTC1481IS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1481IS8#TRPBF is an ultralow power RS-485/RS-422 differential line transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply with a maximum data rate of 2.5 Mbits/s. The device features one driver and one receiver in half-duplex mode, housed in an 8-lead SOIC package. Electrical specifications include a typical quiescent current of 80mA when operating and less than 1mA in shutdown mode. It provides ±10kV ESD protection and includes thermal shutdown circuitry to prevent excessive power dissipation during bus contention.

Drivers, Receivers, Transceivers Feature Summary

• CMOS design ensures low power consumption while maintaining ruggedness against overload and ESD damage
• Driver and receiver outputs feature three-state capability with high impedance maintenance across the common mode range
• Integrated thermal shutdown forces driver outputs into high impedance state to prevent damage from faults
• Fail-safe receiver guarantees a high output state when inputs are left open

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS-422 applications
• Low power RS-485/RS-422 transceiver systems
• Level translator circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging configuration. Confirm the IS8 designation corresponds to the industrial temperature range (-40°C to +85°C) and SOIC-8 package. Ensure compatibility with specific board layout requirements for surface mount installation.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring ultralow power operation in RS-485 networks. The CMOS architecture offers significant power savings over bipolar counterparts. Verify that the 2.5 Mbits/s speed meets system timing requirements and that the 5V supply voltage aligns with the target application's power rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1481 series of ultralow power transceivers. It is pin-compatible with the LTC485. The device supports up to 32 transceivers on a single bus and allows live insertion or removal due to glitch-free driver outputs during power-up and power-down cycles.
