ESCRIPTIO
The LTC
1481 is an ultra-low power differential line trans-
ceiver designed for data transmission standard RS485
applications. It will also meet the requirements of RS422.
The CMOS design offers significant power savings over its
bipolar counterparts without sacrificing ruggedness against
overload or ESD damage. Typical quiescent current is only
80
μ
A while operating and less than 1
μ
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 LTC1481 is fully specified over the commercial and
extended industrial temperature range and is available in
8-pin DIP and SO packages.
