LTC2850/LTC2851/LTC2852

3.3V 20Mbps RS485/RS422

Transceivers

FEATURES

DESCRIPTION

The LTC^®2850, LTC2851 and LTC2852 are low power,

20Mbps RS485/RS422 transceivers operating on 3.3V

supplies.Thereceiverhasaone-eighthunitloadsupporting

upto256nodesperbus(C-,I-grade),andafailsafefeature

that guarantees a high output state under conditions of

floating or shorted inputs.

3.3V Supply Voltage

20Mbps Maximum Data Rate

No Damage or Latchup Up to ±±5ꢀV ꢁHM

ꢁigh Input Impedance Supports 256 Nodes

(C-, I-Grade)

Operation Up to ±25°C (ꢁ-Grade)

Guaranteed Failsafe Receiver Operation Over the

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.

Entire Common Mode Range

Current Limited Drivers and Thermal Shutdown

Delayed Micropower Shutdown: 5µA Maximum

(C-, I-Grade)

Power Up/Down Glitch-Free Driver Outputs

Enhanced ESD protection allows these parts to withstand

up to 15kV (human body model) on the transceiver

interface pins without latchup or damage.

Low Operating Current: 370µA Typical in
