DESCRIPTION…
The SP486E and SP487E are low-power quad differential line drivers 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 SP486 and SP487 devices as well as popular industry standards. As with
the original versions, the SP486E features a common driver enable control and the SP487E
provides independent driver enable controls for each pair of drivers. Both feature wide
common-mode input ranges. Both are available in 16-pin plastic DIP and SOIC packages.
