SP490/SP491  
Full Duplex RS-485 Transceivers  
+5V Only  
Low Power BiCMOS  
Driver/Receiver Enable (SP491)  
RS-485 and RS-422 Drivers/Receivers  
Pin Compatible with LTC490 and  
SN75179 (SP490)  
Pin Compatible with LTC491 and  
SN75180 (SP491)  
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 14-pin DIP and 14-pin NSOIC packages for operation over the commercial and  
industrial temperature ranges.
