The
SP490E is a low power differential line driver/receiver meeting RS-485 and RS-422
standards up to 0Mbps. 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 4-pin DIP and 4-pin NSOIC packages for operation over the
commercial and industrial temperature ranges.
