LTC1481IN8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1481IN8#PBF is an ultralow power RS-485 transceiver manufactured by Analog Devices Inc. It supports data rates up to 2.5 Mbits/s and operates on a single 5V supply (4.75V to 5.25V). The device features one driver and one receiver in half-duplex mode, housed in an 8-pin PDIP package. Quiescent current is typically 80mA with the driver disabled and drops to less than 1mA in shutdown mode. It provides –10kV ESD protection, thermal shutdown, and a fail-safe receiver that guarantees a high output when inputs are open.

Drivers, Receivers, Transceivers Feature Summary

• Ultralow power CMOS design with dedicated shutdown mode for battery applications
• Robust I/O protection including –10kV ESD tolerance and thermal shutdown circuitry
• Fail-safe receiver logic ensures a defined high state during idle or open-bus conditions
• Glitch-free driver outputs enable safe live insertion and removal from the bus

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS-422 communication systems
• Industrial process control networks requiring low standby current
• Multipoint data transmission buses with limited power budgets

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IN8 corresponds to the industrial temperature range (-40°C to +85°C) and PDIP-8 through-hole package configuration. Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs prioritizing minimal quiescent current consumption over high-speed throughput. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range and utilizes a stable 5V power supply.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1481 series of ultralow power line transceivers. It serves as a pin-compatible alternative to older bipolar RS-485 drivers, offering significantly reduced power dissipation while maintaining ruggedness against overload and electrostatic discharge events.
