DESCRIPTION…

The SP488A and SP489A are high speed quad differential line receivers capable of

meeting the RS-485 and RS-422 protocols while running at five times the normal

transmission rates. The SP488A and SP489A are enhanced versions of Sipex's SP488

and SP489 quad RS-485/RS-422 line receivers. The SP488A features a common

receiver enable control; the SP489A 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.
