LTC2862ACDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862ACDD-1#PBF is a low-power, half-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides ±40kV HBM ESD protection on interface pins and Level 4 IEC ESD/EFT compliance. The component utilizes an 8-lead (3mm × 3mm) Plastic DFN package with an exposed pad connected to GND. It operates within a temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates tube packaging when sourcing this component. Confirm the AC grade designation corresponds to the commercial temperature range of 0°C to 70°C for your application requirements. Ensure compatibility with the 8-lead DFN footprint during PCB layout verification.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2862ACDD-1#PBF for applications requiring high-speed transmission up to 20Mbps in electrically noisy environments. This variant is suitable for systems needing robust fault tolerance against large ground loop voltages. Consider the thermal characteristics of the DFN package if operating near the upper temperature limit.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862A series, which includes variants optimized for different data rates and temperature grades. The -1 suffix denotes the high-speed 20Mbps option, while other suffixes may indicate slew-rate limited versions or automotive-grade qualifications. The DD package specifies the compact DFN form factor.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with the LTC2862 and LT1785. Verify electrical specifications and package dimensions before substituting these components.
