LTC2862ACDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862ACDD-2#PBF is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a single 3V to 5.5V supply and supports a maximum data rate of 250kbps with slew-rate limiting for reduced electromagnetic interference. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides Level 4 IEC ESD protection (±8kV contact) and ±40kV HBM protection on the A and B pins. The component includes an extended common mode range of ±25V, guaranteed failsafe receiver operation, and thermal shutdown. It is housed in an 8-lead (3mm × 3mm) Plastic DFN package with an exposed pad connected to ground.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on interface pins across all operational states
• Robust electrostatic discharge immunity meeting Level 4 IEC standards and ±40kV HBM ratings
• Slew-rate limited transmission at 250kbps to minimize electromagnetic interference emissions
• Extended common mode input range of ±25V for reliable communication under large ground loop voltages

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
• Medical equipment interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to 70°C) and 'DD' denotes the 8-lead DFN package. Confirm that the '#PBF' suffix specifies lead-free finish and RoHS compliance. Ensure the ordering information matches the required duplex mode and data rate specifications for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when low electromagnetic interference is critical due to its 250kbps slew-rate limited driver. Choose the AC grade for commercial temperature environments rather than AI or AH grades. Verify that the system requires half-duplex communication and benefits from the integrated ±60V fault tolerance without external protection components.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of robust RS-485/RS-422 transceivers. It is pin-compatible with the standard LTC2862 and LT1785 devices. The '-2' suffix designates the half-duplex, 250kbps slew-rate limited version, distinct from the '-1' high-speed 20Mbps variant. The 'C' suffix identifies the commercial operating temperature range.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include the LTC2862 and LT1785. For higher speed requirements, consider the LTC2862A-1 variants. Automotive applications require parts designated with the '#W' suffix, such as the LTC2862AIS8-2#WPBF.
