LTC486CSW#PBF

Drivers, Receivers, Transceivers Overview

The LTC486CSW#PBF is a low-power quad differential bus driver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports RS-485 and RS-422 standards with an extended common-mode range of –7V to +12V. The device features three-state outputs, thermal shutdown protection, and glitch-free power-up/down behavior for live insertion. Typical supply current is 110µA, with propagation delays of 28ns and skew of 5ns. It is housed in a 16-lead plastic SOIC (SW) package.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential drivers designed for multipoint data transmission
• Extended common-mode range supporting ±7V ground difference
• Thermal shutdown prevents excessive power dissipation during faults
• Glitch-free outputs permit safe live insertion and removal

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 drivers
• Level translator applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required temperature range and packaging format. Cross-reference manufacturer part numbers to validate authenticity and avoid counterfeit components.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low quiescent current and high noise immunity. Verify that the system voltage remains within the specified 4.75V to 5.25V range. Confirm that the load requirements do not exceed the short-circuit current limits or trigger thermal shutdown unnecessarily.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC486 family of low-power RS-485 drivers. It serves as a CMOS alternative to older bipolar counterparts, offering significant power savings while maintaining ruggedness against overload and ESD damage. It is pin-compatible with several industry-standard drivers.
