LTC1481CS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1481CS8#TRPBF is an ultralow power RS-485 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-pin SOIC package. Quiescent current is typically 80mA when operating and drops to less than 1mA in shutdown mode. It supports a common mode range from -7V to 12V and includes thermal shutdown protection.

Drivers, Receivers, Transceivers Feature Summary

• Ultralow power CMOS design for battery-powered applications
• Integrated thermal shutdown circuit prevents excessive power dissipation
• Fail-safe receiver guarantees high output state when inputs are open
• Glitch-free driver outputs permit live insertion or removal

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS-422 communication systems
• Low power industrial bus networks
• Level translation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging distinct from tube variants like #PBF. Confirm the CS8 designation corresponds to the commercial temperature range (0°C to 70°C) rather than the extended industrial range found in IS8 parts. Ensure compatibility with existing PCB footprints for the S8 plastic small outline package.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring minimal standby current and robust ESD protection up to 10kV. It serves as a pin-compatible replacement for the older LTC485 series. Consider the IS8 variant if operation below 0°C is required. Verify that the 5V supply voltage aligns with the system architecture before integration.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1481 family of ultralow power RS-485 transceivers. It shares architectural similarities with the LTC485 but utilizes advanced CMOS technology to significantly reduce power consumption. The family includes variants with different temperature ratings and packaging options to suit various industrial and commercial deployment scenarios.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is a direct pin-compatible alternative within the same manufacturer portfolio.
