Description
General part information
LTC2856 Series
The LTC2856-1, LTC2856-2, LTC2857-1, LTC2857-2, LTC2858-1 and LTC2858-2 are low power, RS485/RS422 transceivers operating on 5V supplies at maximum data rates of 20Mbps or 250kbps for low EMI. The receiver has a 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 thermal shutdown.Enhanced ESD protection allows these parts to withstand ±15kV (human body model) on the transceiver interface pins without latch-up or damage.Part NumberMAX Data Rate (Mbps)DuplexPackageLTC2856-120HalfMSOP-8, DFN-8LTC2856-20.25HalfMSOP-8, DFN-8LTC2857-120FullMSOP-8, DFN-8LTC2857-20.25FullMSOP-8, DFN-8LTC2858-120FullMSOP-10, DFN-10LTC2858-20.25FullMSOP-10, DFN-10ApplicationsLow Power RS485/RS422 TransceiverLevel TranslatorBackplane Transceiver
