DESCRIPTION…
The SP486 and SP487 are low–power quad differential line drivers meeting RS-485 and RS-422
standards. The SP486 features a common driver enable control; the SP487 provides indepen-
dent driver enable controls for each pair of drivers. Both feature tri–state outputs and wide
common–mode input range. Both are available in 16–pin plastic DIP and SOIC packages.
