DESCRIPTION…
The
SP488E
and
SP489E
are low-power quad differential line receivers that meet the
specifications of RS-485 and RS-422 serial protocols with enhanced ESD performance. The
ESD tolerance has been improved on these devices to over +15kV for both Human Body
Model and IEC1000-4-2 Air Discharge Method. These devices are superior drop-in replace-
ments to
Sipex's SP488
and
SP489
devices as well as popular industry standards. As with
the original versions, the
SP488E
features a common receiver enable control and the
SP489E
provides independent receiver enable controls for each pair of receivers. Both
feature wide common-mode input ranges. The receivers have a fail-safe features which
forces a logic "1" output when receiver inputs are left floating. Both are available in 16-pin
plastic DIP and SOIC packages.
