DESCRIPTION…
The
SP488
and
SP489
are low–power quad differential line receivers meeting RS-485 and RS-422
standards. The
SP488
features a common receiver enable control; the
SP489
provides independent
receiver enable controls for each pair of receivers. Both feature tri–state outputs and wide common–
mode input range. The receivers have a fail–safe feature which forces a logic “1” output when receiver
inputs are left floating. Both are available in 16–pin plastic DIP and SOIC packages.
