Features, Applications

or RS-422 Applications Quad Differential Line Receivers Tri­state Output Control 120ns Typical Receiver Propagation Delays to +12V Common Mode Input Range 1mA Supply Current Single +5V Supply Operation Pin Compatible with SN75175, LTC488 and LTC489

DESCRIPTION... The SP488 and SP489 are low­power 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 tri­state outputs and wide common­ mode input range. The receivers have a fail­safe feature which forces a logic "1" output when receiver inputs are left floating. Both are available in 16­pin plastic DIP and SOIC packages.

These are stress ratings only and functional operation of the device at these or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
