SP486E集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

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 Sipexs 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.
