LTC486IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC486IN#PBF is a low power quad differential bus driver designed for multipoint data transmission in RS485 applications. It operates on a single 5V supply with an input voltage range of 4.75V to 5.25V and draws a typical supply current of 110µA. The device features three-state outputs, maintaining high impedance across the entire common-mode range of –7V to +12V. It supports data rates up to 10Mb/s with typical propagation delays of 28ns and skew of 5ns. The component includes thermal shutdown protection and glitch-free outputs for live insertion. It is housed in a 16-lead plastic DIP package and functions within an industrial temperature range of –40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and operating temperature range. The IN suffix indicates a 16-lead PDIP package with an industrial temperature rating of –40°C to +85°C. Confirm RoHS compliance status as required by project specifications. Ensure the procurement channel provides valid traceability documentation for Analog Devices components.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for RS485 multipoint networks requiring low quiescent current and extended common-mode voltage tolerance. The wide common-mode range allows for significant ground potential differences between connected devices. Verify that the application does not require receiver functionality, as this part number contains only drivers. Consider the thermal shutdown feature for environments prone to bus contention or output short circuits.

Drivers, Receivers, Transceivers Part Context

The LTC486 belongs to the Analog Devices family of low power RS485 interface integrated circuits. It serves as a dedicated line driver counterpart to receivers like the LTC489. The device is engineered to meet RS485 standards while offering CMOS power efficiency compared to older bipolar technologies. It is often utilized in industrial automation and building control systems where reliable half-duplex communication is necessary.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet lists the SN75172, DS96172, µA96172, and DS96F172 as pin-compatible alternatives. Designers should verify electrical parameter compatibility before substitution.
