SP486E/487EDS/06 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. n RS-485 or RS-422 Applications n Quad Differential Line Drivers n Driver Output Disable n –7V to +12V Common Mode Output Range n 100µA Supply Current n Single +5V Supply Operation n Superior Drop-in Replacement for SN75172, SN75174, LTC486, and LTC487 n Improved ESD Specifications: +15kV Human Body Model +15kV IEC1000-4-2 Air Discharge +8kV IEC1000-4-2 Contact Discharge SP487EDI1 DO 1A DO 1B EN 1/EN2 DO 2B DO 2A DI2 GND VCC DI4 DO 4A DO 4B EN 3/EN4 DO 3B DO 3A DI3 SP486EDI1 DO 1A DO 1B EN DO 2B DO 2A DI2 GND VCC DI4 DO 4A DO 4B EN DO 3B DO 3A DI3 SP486E and SP487E Enhanced Quad RS-485/RS-422 Line Drivers
