LTC1685CS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1685CS8#TRPBF is a high-speed, precision delay RS485/RS422 transceiver operating from a single 5V supply. It supports data rates up to 52Mbps with a typical propagation delay of 18.5ns and a tight delay variation of -3.5ns over temperature. The device features low skew (500ps typ), a wide common mode input range (-7V to 12V), and guaranteed fail-safe operation. It includes short-circuit and thermal shutdown protection, drawing only 7mA of supply current.

Drivers, Receivers, Transceivers Feature Summary

• Precision timing architecture ensures stable propagation delays and minimal skew across temperature variations.
• Guaranteed fail-safe receiver operation maintains a high output state when inputs are open or shorted within the full common mode range.
• Integrated short-circuit and thermal shutdown protection safeguards the driver and receiver outputs during fault conditions.
• High input resistance remains above 22kΩ even when the device is unpowered or disabled.

Drivers, Receivers, Transceivers Applications

• High-speed backplane point-to-point transceiver applications
• Fast-20 and Fast-40 High Voltage Differential SCSI systems
• STS-1/OC-1 data transmission links
• Level translation between different voltage domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging. Confirm the CS8 variant corresponds to the commercial temperature range of 0°C to 70°C. Ensure the order matches the specific package style and pinout requirements for the target PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component when precise timing alignment is critical for high-speed differential signaling. It is suitable for environments requiring robust fault protection and wide common mode voltage tolerance. Consider the 52Mbps limit and 5V supply constraint against system requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1685 family of high-speed RS485 transceivers. It is pin-compatible with the older LTC485 model, facilitating direct upgrades in existing designs. Related parts include the quad receiver variants LTC1518/LTC1519 and the full-duplex LTC1686/LTC1687.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is a confirmed pin-compatible substitute with lower speed capabilities. For quad configurations, consider the LTC1518 or LTC1519 receivers. Full-duplex alternatives include the LTC1686 and LTC1687 models.
