DESCRIPTION
3.3V 20Mbps RS485/RS422
Transceivers
The LT C
®
2850, LTC2851 and LTC2852 are low power,
20Mbps RS485/RS422 transceivers operating on 3.3V
supplies. 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 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
up to ±15kV (human body model) on the transceiver
interface pins without latchup or damage.
