20Mbps and Slew Rate
Limited 15kV RS485/RS422
Transceivers
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 failsafe feature that guarantees a high
outputstateunderconditionsoffloatingorshortedinputs.
The driver maintains a high output impedance over the
entire common mode range when disabled or when the
supplyisremoved.Excessivepowerdissipationcausedby
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 latchup or damage.
