LTC1687CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1687CS#PBF is a high-speed, precision delay, full-duplex RS485 transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply with a typical supply current of 7mA and supports data rates up to 52Mbps. The device features guaranteed fail-safe operation over the entire common mode range of –7V to 12V and includes short-circuit and thermal shutdown protection. It utilizes an 8-lead plastic SOIC (S8) package.

Drivers, Receivers, Transceivers Feature Summary

• Precision propagation delay architecture ensures stable timing performance across wide temperature variations.
• Fail-safe receiver guarantees a logic HIGH output when inputs are shorted or left floating within the specified common mode range.
• Integrated short-circuit and thermal shutdown protection safeguards the driver and receiver during fault conditions.

Drivers, Receivers, Transceivers Applications

• High speed RS485/RS422 full duplex transceivers
• Level translator circuits
• Backplane transceivers
• STS-1/OC-1 data transceivers
• Signal repeaters

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm that the CS variant meets the required commercial operating temperature range of 0°C to 70°C for your application environment. Ensure the 8-lead SOIC footprint matches your PCB layout constraints.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC1687CS#PBF when precise timing skew and low duty cycle distortion are critical for high-speed data transmission. This component is suitable for applications requiring robust fail-safe behavior under line faults. Consider the LTC1686 if driver enable control is not needed, as it lacks the DE pin found on the LTC1687.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC1686/LTC1687 family of high-speed RS485 transceivers designed for precision timing applications. It shares architectural similarities with the LTC490 and LTC491 series but offers superior propagation delay stability. The part is intended for demanding industrial and telecommunications environments requiring reliable high-speed communication.
