Description

The LTC2855IDE is a dual RS485/RS422 transceiver designed by Analog Devices (formerly Linear Technology) for high-speed, low-power communication. It supports data rates up to 20 Mbps and operates from a single 3.3V supply. The device features a ±15kV ESD protection on the transceiver pins, ensuring robust performance in harsh environments.
The LTC2855IDE is capable of full-duplex communication and is ideal for systems requiring multiple transceivers on a single bus, thanks to its high receiver and driver common-mode range. It offers low power consumption, with a shutdown mode that reduces current draw to less than 1 μA.
Integrated fail-safe circuitry ensures the receiver outputs remain in a known state when inputs are open, shorted, or terminated but undriven. The device is available in a 16-lead narrow SSOP package, making it suitable for space-constrained applications.
Overall, the LTC2855IDE is a reliable and efficient solution for industrial, automotive, and networking applications requiring robust RS485/RS422 communication.
