SP488A - High Speed Quad RS-485/RS-422 Line Receivers

General 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.

Key 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. RI1B RI1A RO1 EN RO2 RI2A RI2B GND 1 2 3 4 5 6 7 8 SP488A 1 4 16 15 14 13 12 VCC RI4B RI4A RO4 EN RO3 RI3A R.
