DESCRIPTION  
The SP1490E is a low power differential line driver/receiver meeting RS-485 and RS-422  
standards up to 20Mbps. The SP1491E is identical to the SP1490E with the addition of driver  
and receiver tri-state enable lines. Both products feature ±200mV receiver input sensitivity,  
over wide common mode range. The SP1490E is available in 8-pin plastic DIP and 8-pin  
NSOIC packages for operation over the commercial and industrial temperature ranges. The  
SP1491E is available in 14-pin DIP and 14-pin NSOIC packages for operation over the  
commercial and industrial temperature ranges.
