FullꢀDuplexꢀRS-485ꢀTransceivers  
FEATURES  
• +5V Only  
• Low Power BiCMOS  
• Driver/Receiver Enable (SP49ꢀ)  
• RS-485 and RS-422 Drivers/Receivers  
• Pin Compatible with LTC490 and  
SN75ꢀ79 (SP490)  
• Pin Compatible with LTC49ꢀ and  
SN75ꢀ80 (SP49ꢀ)  
Now Available in Lead Free Packaging  
DESCRIPTION  
The SP490 is a low power differential line driver/receiver meeting RS-485 and RS-422  
standards up to 5Mbps. The SP491 is identical to the SP490 with the addition of driver and  
receiver tri-state enable lines. Both products feature ±200mV receiver input sensitivity, over  
wide common mode range. The SP490 is available in 8-pin plastic DIP and 8-pin NSOIC  
packages for operation over the commercial and industrial temperature ranges. The SP491  
is available in ꢀ4-pin DIP and ꢀ4-pin NSOIC packages for operation over the commercial  
and industrial temperature ranges.
