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.
