SP486E/487E Enhanced Quad RS-485/RS-422 Line Drivers

© Copyright 2000 Sipex Corporation

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.
