LTC2864IS-1#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2864IS-1#PBF is a full-duplex RS-422/RS-485 transceiver operating on a 3V to 5.5V supply. It supports a maximum data rate of 20Mbps and features ±60V fault protection on transmission lines during all modes, including power-down. The device provides an extended common mode range of ±25V and ±15kV ESD protection on interface pins. It includes one driver and one receiver with logic-selectable shutdown capabilities. The component operates within a temperature range of -40°C to +85°C and is housed in a 14-lead plastic SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V
• Extended common mode input range of ±25V for noisy environments
• High input impedance supporting up to 256 nodes on the bus
• Guaranteed failsafe receiver operation under open or shorted conditions

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA) systems
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC controls

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C). Confirm the '-1' designation corresponds to the 20Mbps high-speed variant rather than the slew-rate limited 250kbps version. Ensure the '#PBF' suffix confirms lead-free RoHS compliance. Cross-reference the 14-pin SO package dimensions against the target PCB footprint requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model when full-duplex communication is required alongside high-speed data rates up to 20Mbps. The IS-1 suffix ensures suitability for industrial environments requiring wide thermal tolerance. Verify that the system ground loops do not exceed the ±25V common mode limit. Consider the LTC2864IS-2#PBF if lower electromagnetic interference via a 250kbps slew-limited mode is prioritized over raw speed.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of rugged transceivers designed for harsh electrical environments. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades. The series distinguishes itself through integrated BiCMOS technology that enables robust fault tolerance without external protection components, simplifying board layout and reducing overall system cost.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2864IS-2#PBF: Offers identical pinout and functionality but operates at a reduced 250kbps data rate with slew limiting for lower EMI.
