Features, Applications

or RS-422 Applications Quad Differential Line Drivers Driver Output Disable to +12V Common Mode Output Range 100µA Supply Current Single +5V Supply Operation Superior Drop-in Replacement for 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.

These are stress ratings only and functional operation of the device at these or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
