DESCRIPTION

3.3V 20Mbps RS485/RS422

Transceivers

The LTC®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.
