LTC486CSW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC486CSW#TRPBF is a low power differential bus driver designed for multipoint data transmission in RS485 applications, meeting RS422 requirements. It features an extended common-mode range from –7V to +12V and operates on a single 5V supply (4.75V to 5.25V). The device provides four drivers with three-state outputs and includes thermal shutdown protection. Typical supply current is 110µA, and propagation delay is 28ns typical with 5ns skew. It is housed in a 16-lead plastic SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• CMOS design offers significant power savings over bipolar counterparts while maintaining ruggedness against overload or ESD damage.
• Thermal shutdown circuit prevents excessive power dissipation by forcing outputs into a high impedance state during faults.
• Power-up/down glitch-free driver outputs permit live insertion and removal of the package without disrupting the bus.

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 drivers
• Level translator

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required temperature grade and packaging format. Confirm that the SW package designation corresponds to the 16-lead plastic SOIC form factor. Ensure the TRPBF suffix indicates tape and reel delivery. Cross-reference the manufacturer part number with official documentation to validate lead-free finish compliance before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low quiescent current for multipoint communication networks. Verify that the operating temperature range aligns with the commercial specification if ambient conditions exceed industrial limits. Ensure the load resistance meets RS485 standards to maintain output voltage specifications. Check pin compatibility with existing designs referencing SN75172 or DS96172 footprints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC486 series of quad low power RS485 drivers. It serves as a robust interface solution for half-duplex data transmission over twisted pair cables. The device complements other Analog Devices interface products by providing fault protection and high common-mode rejection capabilities suitable for noisy industrial environments.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible alternatives include the SN75172, DS96172, µA96172, and DS96F172. Verify electrical characteristics such as propagation delay and short-circuit current when substituting these parts to ensure system timing and fault tolerance remain within acceptable limits.
