DESCRIPTION…

The SP490E is a low power differential line driver/receiver meeting RS-485 and RS-422

standards up to 10Mbps. The SP491E is identical to the SP490E with the addition of driver

and receiver tri-state enable lines. Both products feature ±200mV receiver input sensitivity,

over wide common mode range. The SP490E is available in 8-pin plastic DIP and 8-pin NSOIC

packages for operation over the commercial and industrial temperature ranges. The SP491E

is available in 14-pin DIP and 14-pin NSOIC packages for operation over the commercial and

industrial temperature ranges.
