Overview
® SP488E and SP489E Enhanced Quad RS-485/RS-422 Line Receivers s s s s s s s RS-485 or RS-422 Applications Quad Differential Line Receivers Receiver Output Disable –7V to +12V Common Mode Input Range 1mA Supply Current Single +5V Supply Operation Superior Drop-in Replacement for SN75173, SN75175, LTC488 and LTC489 s Improved ESD Specifications: +15kV Human Body Model +15kV IEC1000-4-2 Air Discharge +8kV IEC1000-4-2 Contact Discharge DESCRIPTION… The SP488E and SP489E are low-power quad differential line receivers that meet the specifications of RS-485 and RS-422 serial protocols with enhanced ESD performance.
The ESD tolerance has been improved on these devices to over +15kV for both Human Body Model and IEC1000-4-2 Air Discharge Method.
These devices are superior drop-in replacements to Sipex's SP488 and SP489 devices as well as popular industry standards.
As with the original versions, the SP488E features a common receiver enable control and the SP489E provides independent receiver enable controls for each pair of receivers.
Both feature wide common-mode input ranges.
The receivers have a fail-safe features which forces a logic "1" output when receiver inputs are left floating.
Both are available in 16-pin plastic DIP and SOIC packages.
