3.3V Ultralow Power  
RS485 Transceiver  
U
DESCRIPTIO  
FEATURES  
The LTC®1480 is an ultralow power differential line trans-  
ceiver which provides full RS485 compatibility while oper-  
ating from a single 3.3V supply. It is designed for data  
transmission standard RS485 applications with extended  
common mode range (12V to –7V). It also meets the  
requirements of RS422 and features high speed operation  
up to 2.5Mb/s. The CMOS design offers significant power  
savings without sacrificing ruggedness against overload  
or ESD damage. Typical quiescent current is only 300µA  
while operating and 1µA in shutdown.

10ns Skew  
■
The driver and receiver feature three-state outputs, with  
the driver outputs maintaining high impedance over the  
entire common mode range. Excessive power dissipation  
caused by bus contention or faults is prevented by a  
thermal shutdown circuit which forces the driver outputs  
into a high impedance state. The receiver has a fail-safe  
feature which guarantees a high output state when the  
inputs are left open.
