LTC1481CS8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1481CS8#PBF is an ultralow power RS-485/RS-422 differential line transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply (4.75V to 5.25V) and supports data rates up to 2.5 Mbits/s. The device features one driver and one receiver with three-state outputs, drawing a maximum of 300mA when enabled and less than 1mA in shutdown mode. It includes thermal shutdown protection, fail-safe receiver logic, and ±10kV ESD protection. The component is housed in an 8-lead SOIC package and is specified for commercial temperature ranges.

Drivers, Receivers, Transceivers Feature Summary

• Ultralow power CMOS design significantly reduces current consumption compared to bipolar counterparts while maintaining ruggedness against overload and ESD damage.
• Integrated thermal shutdown circuit prevents excessive power dissipation by forcing driver outputs into a high impedance state during faults or bus contention.
• Fail-safe receiver feature guarantees a high output state when inputs are left open, ensuring reliable communication under undefined conditions.

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485 and RS-422 communication systems
• Low power industrial RS-485 networks
• Level translation applications requiring glitch-free operation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CS8 corresponds to the narrow plastic SOIC package and commercial temperature range. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the ordering part number matches the required pinout and electrical specifications for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring minimal quiescent current in standby modes. Verify that the system bus does not exceed the 32-transceiver limit. Ensure the operating environment remains within the specified commercial temperature range. Check compatibility with existing logic levels for DE and RE control signals.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC1481 series of ultralow power transceivers. It is pin-compatible with the LTC485, facilitating direct upgrades for legacy designs seeking reduced power consumption. The series emphasizes low current draw without compromising the common-mode voltage range or ESD immunity required for robust RS-485 communication.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is a pin-compatible alternative within the same family. Verify if the extended industrial temperature range of other variants is necessary for the specific deployment environment.
