DESCRIPTION…
The SP488 and SP489 are low–power quad differential line receivers meeting RS-485 and RS-422
standards. The SP488 features a common receiver enable control; the SP489 provides independent
receiver enable controls for each pair of receivers. Both feature tri–state outputs and wide common–
mode input range. The receivers have a fail–safe feature which forces a logic “1” output when receiver
inputs are left floating. Both are available in 16–pin plastic DIP and SOIC packages.
