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. The receiver has a one-eighth unit load sup-  
porting up to 256 nodes per bus, and a failsafe feature  
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  
Guaranteed Failsafe Receiver Operation Over the  
Entire Common Mode Range  
Current Limited Drivers and Thermal Shutdown  
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.  
Delayed Micropower Shutdown: 5µA Maximum  
Power Up/Down Glitch-Free Driver Outputs  
Low Operating Current: 370µA Typical in Receive  
Mode  
Compatible with TIA/EIA-485-A Specifications  
Enhanced ESD protection allows these parts to withstand  
up to 15ꢀV ꢁhuman body modelꢂ on the transceiver  
interface pins without latchup or damage.  
Available in 8-Pin and 10-Pin 3mm × 3mm DFN,  
8-Pin and 10-Pin MSOP, and 8-Pin and 14-Pin SO
