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.
