SP488 - Quad RS-485/RS-422 Line Receivers

General Description

The SP488 and SP489 are low

power quad differential line receivers meeting RS-485 and RS-422 standards.

Key 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. RI1B RI1A RO1 EN RO2 RI2A RI2B GND 1 2 3 4 5 6 7 8 SP488 1 4 16 15 14 13 12 VCC RI4B RI4A RO4 EN RO3 RI3A RI.

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.
