LTC2858CMS-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2858CMS-1#PBF is a low-power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports a maximum data rate of 20Mbps. The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling support for up to 256 nodes per bus in C and I-grade applications. It includes enhanced ESD protection rated at ±15kV (HBM) on interface pins without latchup or damage. The component incorporates current-limited drivers and thermal shutdown to prevent excessive power dissipation during bus contention or faults. It is housed in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• Enhanced electrostatic discharge protection up to ±15kV HBM
• High input impedance supporting extensive network node counts
• Integrated thermal shutdown and current limiting for fault protection

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translator circuits
• Backplane transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix CMS-1 against official Analog Devices documentation to confirm the commercial temperature range and 10-lead MSOP package configuration. Ensure compatibility with system voltage requirements of 4.5V to 5.5V. Cross-reference the part number with manufacturer databases to confirm availability status and lead times prior to procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication over RS485 or RS422 networks. It is suitable for environments demanding high noise immunity due to its failsafe receiver operation and robust ESD protection. Consider the 20Mbps data rate capability for high-speed serial communication needs while maintaining low static power consumption.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power transceivers from Analog Devices. The family includes half-duplex variants like the LTC2856 and other full-duplex options such as the LTC2857. The LTC2858 specifically adds enable controls for both the driver and receiver, offering greater flexibility in managing bus states compared to the non-enable LTC2857.
