LTC2852IS#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852IS#PBF is a low-power, full-duplex RS-485/RS-422 transceiver operating on a 3V to 3.6V supply. It supports data rates up to 20Mbps and features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling support for up to 256 nodes per bus. The device includes current-limited drivers with thermal shutdown protection and enhanced ESD protection rated at ±15kV (HBM). Typical supply currents are 370µA in receive mode and 450µA in transmit mode. It operates within an industrial temperature range of –40°C to +85°C and is housed in a 14-lead SO package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver control via DE and RE pins
• Guaranteed failsafe receiver output ensuring logic-high state during floating or shorted inputs
• High input impedance receiver supporting up to 256 nodes on the bus without loading
• Robust protection against short circuits, excessive power dissipation, and electrostatic discharge

Drivers, Receivers, Transceivers Applications

• Multinode industrial communication networks requiring high node density
• Backplane transceivers in embedded systems
• Level translation between different voltage domains in RS-485/RS-422 interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IS' confirms the Industrial temperature grade (-40°C to +85°C) and the 'S' indicates the 14-lead SOIC package. Confirm '#PBF' denotes lead-free compliance. Cross-reference the manufacturer's official ordering guide to ensure the part number matches the required duplex configuration and package type before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside high bus capacity. The one-eighth unit load specification allows connecting significantly more devices than standard RS-485 receivers. Ensure the application environment stays within the specified voltage and temperature limits to maintain the guaranteed failsafe and ESD performance characteristics.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power transceivers from Analog Devices. While the LTC2850 offers half-duplex operation and the LTC2851 provides full-duplex without enable controls, the LTC2852 combines full-duplex capability with dedicated driver enable (DE) and receiver enable (RE) pins for precise control over transmission states.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the LTC2852CS#PBF (Commercial grade), LTC2852HS#PBF (High-temp grade), and variants in MSOP-10 or DFN-10 packages such as LTC2852MS#PBF or LTC2852DD#PBF, provided the pinout and electrical specifications remain compatible.
