LTC2852IMS#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852IMS#PBF is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a 3.3V supply and supports data rates up to 20Mbps. The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling support for up to 256 nodes per bus in C-grade and I-grade configurations. It includes enhanced ESD protection rated at ±15kV (HBM), current-limited drivers, and thermal shutdown capabilities. The typical supply current is 370µA in receive mode and 450µA in transmit mode. The component is housed in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• High input impedance supporting up to 256 nodes per bus
• Enhanced ESD protection up to ±15kV HBM without latchup
• Current-limited outputs and thermal shutdown for fault protection

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translators
• Backplane transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and tape-and-reel packaging specifications. Confirm that the IMS designation corresponds to the 10-lead MSOP package variant required for your design. Ensure compatibility with the intended temperature grade before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside low power consumption. The high input impedance makes it suitable for multi-drop networks requiring more than standard node counts. Verify that the 3.3V supply voltage aligns with system requirements and that the MSOP package fits the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power transceivers. It shares core electrical characteristics with the LTC2850 and LTC2851 but provides full-duplex capability unlike the half-duplex LTC2850. It offers similar performance to the LTC2851 but includes dedicated enable pins for the driver and receiver, allowing for precise control over transceiver states.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2851MS#PBF serves as a functional substitute if enable pins are not utilized. The LTC2850 series may be considered for half-duplex applications only. Verify pinout compatibility and package dimensions when substituting.
