SP488E
SP488E is Enhanced Quad RS-485/RS-422 Line Receivers manufactured by Sipex.
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 +15k V for both Human Body Model and IEC1000-4-2 Air Discharge Method. These devices are superior drop-in replacements to Sipex's SP488 and SP489 devices as well as popular industry standards. As with the original versions, the SP488E features a mon receiver enable control and the SP489E provides independent receiver enable controls for each pair of receivers. Both feature wide mon-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.
