LTC1686CS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1686CS8#TRPBF is a high-speed, full-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply and supports data rates up to 52Mbps. The device features precision propagation delay with a typical value of 18.5ns and low skew of 500ps. It includes fail-safe receiver operation over the entire common mode range (-7V to 12V) and maintains an input resistance of at least 22kΩ when unpowered. The component provides short-circuit protection for both driver and receiver outputs, along with thermal shutdown capabilities.

Drivers, Receivers, Transceivers Feature Summary

• Precision timing architecture ensures stable propagation delays and minimal skew across temperature variations.
• Fail-safe receiver guarantees a logic high output state during input faults or open lines within the specified common mode range.
• Integrated short-circuit detection reduces output drive current significantly to protect against excessive power dissipation.
• Thermal shutdown circuitry prevents damage during conditions of excessive heat generation.

Drivers, Receivers, Transceivers Applications

• High speed RS-485/RS-422 full duplex transceivers
• Level translator circuits
• Backplane transceiver applications
• STS-1/OC-1 data transceivers
• Signal repeaters

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm that the CS8 designation corresponds to the commercial temperature range (0°C to 70°C). Ensure compatibility with the required SOIC-8 package dimensions and pinout configuration before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring precise timing synchronization between driver and receiver paths. Consider the 52Mbps maximum data rate capability for high-speed serial communication links. Evaluate the need for fail-safe operation in noisy environments where input lines may become disconnected or shorted.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1686/LTC1687 family of precision delay RS-485 transceivers. The LTC1686 variant lacks independent driver and receiver enable pins compared to the LTC1687. Both devices share identical electrical characteristics and are designed for robust performance in industrial communication networks.

Drivers, Receivers, Transceivers Replacement Considerations

LTC1686CS8#PBF serves as a direct functional substitute differing only in tube packaging instead of tape and reel format. Verify pin compatibility if replacing with other RS-485 transceivers, as interface control signals may differ between manufacturers.
