LTC1482IS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1482IS8#TRPBF is a low power RS-485 transceiver manufactured by Analog Devices Inc. It features an active low carrier detect output and receiver fail-safe capabilities. The device operates on a single 5V supply with a maximum data rate of 4Mbps. Supply current is 700µA max with the driver disabled, 900µA max in driver mode without load, and 20µA max in shutdown mode. It supports up to 32 transceivers on the bus and provides enhanced ESD protection of -15kV (HBM). The IS8 suffix indicates an industrial temperature range (-40°C to +85°C) and an 8-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Active low open-drain carrier detect output for cable insertion detection
• Guaranteed high receiver output state for floating or shorted inputs
• Enhanced ESD protection withstands -15kV human body model discharge
• Thermal shutdown circuit prevents damage from bus contention

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer declarations. Ensure the component matches the required industrial specifications before integration into final designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when carrier detection functionality is required alongside standard RS-485 communication. The integrated fail-safe mechanism simplifies design by eliminating external pull-up resistors for idle states. Verify that the 4Mbps data rate meets system requirements and that the 5V supply voltage aligns with the target platform.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1482 series of low power RS-485 transceivers. It shares functional similarities with the LTC1481 and LTC1483 but includes unique carrier detect logic. The IS8 variant specifically denotes the industrial temperature range and surface-mount SOIC packaging configuration.

Drivers, Receivers, Transceivers Replacement Considerations

LTC1482CS8#PBF offers identical electrical performance in a commercial temperature range with SOIC-8 packaging. LTC1482CN8#PBF provides the same functionality in a PDIP-8 through-hole package.
