The LTC2854 are low power, 20Mbps RS485/RS422 transceivers operating on 3.3V supplies. The receiver includes a logic-selectable 120Ω termination, one-eighth unit load supporting up to 256 nodes per bus (C-, I-Grade), and a fail-safe feature that guarantees a high output state under conditions of floating or shorted inputs.
The driver maintains a high output impedance over the entire common mode range when disabled or when the supply is removed. Excessive power dissipation caused by bus contention or a fault is prevented by current limiting all outputs and by a thermal shutdown.
Enhanced ESD protection allows the LTC2854 to withstand ±25kV (human body model).
