® SP486E and SP487E Enhanced Quad RS-485/RS-422 Line Drivers s s s s s s s s RS-485 or RS-422 Applications Quad Differential Line Drivers Driver Output Disable –7V to +12V Common Mode Output Range 100µA Supply Current Single +5V Supply Operation Superior Drop-in Replacement for SN75172, SN75174, LTC486, and LTC487 Improved ESD Specifications: +15kV Human Body Model +15kV IEC1000-4-2 Air Discharge +8kV IEC1000-4-2 Contact Discharge 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 replacements 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.
