3.3V Ultralow Power
RS485 Transceiver
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 300
A
while operating and 1
A in shutdown.
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.
The LTC1480 is fully specified over the commercial and
extended industrial temperature range. The LTC1480 is
available in 8-pin SO and DIP packages.
