LTC2864CDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864CDD-1#PBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. The device features ±60V fault protection on transmission lines, ±15kV ESD protection on interface pins, and an extended common mode range of ±25V. Packaged in a 10-lead DFN (3mm x 3mm) with an exposed pad, it includes one driver and one receiver with logic-selectable shutdown capabilities.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V during all modes of operation
• Enhanced ESD protection rated at ±15kV HBM on interface pins without latchup
• Extended common mode input range of ±25V for reliable communication in noisy environments
• Guaranteed failsafe receiver operation ensuring a logic high state when inputs are unconnected

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and signal integrity needs before procurement. Confirm availability through authorized distributors as stock levels fluctuate.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance on RS-485 or RS-422 buses. The full-duplex configuration with separate transmit and receive lines suits bidirectional communication needs. Consider the 20Mbps rate for high-speed data transfer or verify if lower speed variants are sufficient for cost optimization.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of low-power, fault-protected transceivers. It shares pinout compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades in existing designs. The C-grade designation indicates a commercial operating temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with LT1785 and LT1791 devices. Verify electrical specifications such as current consumption and propagation delay to ensure functional equivalence in the target circuit design.
