DESCRIPTION…
The
SP488A
and
SP489A
are high speed quad differential line receivers capable of
meeting the RS-485 and RS-422 protocols while running at five times the normal
transmission rates. The
SP488A
and
SP489A
are enhanced versions of
Sipex's
SP488
and SP489 quad RS-485/RS-422 line receivers. The
SP488A
features a common
receiver enable control; the
SP489A
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.
