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.
