LTC1690CS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1690CS8#TRPBF is a low-power differential driver and receiver pair compatible with RS485 and RS422 standards, manufactured by Analog Devices Inc. It operates on a single 5V supply and supports data rates up to 5 Mbps. The device features fail-safe receiver outputs that guarantee a high state when inputs are open or shorted. It includes thermal shutdown protection against bus contention and offers robust ESD protection rated at –15kV (Human Body Model). The component is housed in an 8-lead SOIC package and is specified for commercial temperature ranges.

Drivers, Receivers, Transceivers Feature Summary

• Fail-safe receiver output guarantees a high logic state when inputs are floating, shorted, or terminated without a signal present.
• Integrated thermal shutdown circuit prevents excessive power dissipation by forcing driver outputs into a high impedance state during faults.
• High ESD protection capability of –15kV Human Body Model and IEC1000-4-2 Level 4 contact discharge tolerance.

Drivers, Receivers, Transceivers Applications

• Battery-powered RS485/RS422 communication systems
• Low power RS485/RS422 transceiver circuits
• Level translation between different voltage domains
• Line repeater applications for extended cable distances

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging configuration. Confirm the CS8 designation corresponds to the 8-lead plastic small outline package. Ensure the part number matches the exact manufacturer specifications for the intended operating temperature range before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for full-duplex RS485/RS422 applications requiring low power consumption and integrated fault protection. Consider the pin compatibility with SN75179 if replacing existing designs. Evaluate the 5V supply requirement and ensure the load conditions align with the specified differential output voltage limits.

Drivers, Receivers, Transceivers Part Context

The LTC1690 family provides complete power supply monitoring and battery control functions for microprocessor reset, battery backup, CMOS RAM write protection, power failure warning and watchdog timing.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC490 is a pin-compatible alternative within the same product family. Verify functional equivalence regarding driver/receiver characteristics and package dimensions before substitution.
