SP481E / SP485E  
Enhanced Low Power Half-Duplex  
RS-485 Transceivers  
• +5V Only  
• Low Power BiCMOS  
• Driver / Receiver Enable for Multi-Drop  
• Low Power Shutdown mode (SP481E)  
• Enhanced ESD Specifications:  
+/-ꢀ5kV Human Body Model  
+/-15kV IEC61000-4-2 Air Discharge  
• Available in RoHS Compliant, Lead Free  
The SP481E and SP485E are a family of half-duplex transceivers that meet the specifications  
of RS-485 and RS-422 serial protocols with enhanced ESD performance. The ESD toler-  
ance has been improved on these devices to over +ꢀ5kV for both Human Body Model and  
IEC61000-4-2 Air Discharge Method. These devices are pin-to-pin compatible with Exar's  
SP481 and SP485 devices as well as popular industry standards. As with the original ver-  
sions, the SP481E and SP485E feature Exar's BiCMOS design allowing low power opera-  
tion without sacrificing performance. The SP481E and SP485E meet the requirements of  
the RS-485 and RS-422 protocols up to 10Mbps under load. The SP481E is equipped with  
a low power shutdown mode.
