SP485CN
The SP483 and SP485 are a family of half-duplex transceivers that meet the specifications
of RS-485 and RS-422. Their BiCMOS design allows low power operation without sacrificing
performance. The SP485 meets the requirements of RS-485 and RS-422 up to 5Mbps. Additionally, the SP483 is equipped with a low power Shutdown mode. The SP483 is internally
slew rate limited to reduce EMI and can meet the requirements of RS-485 and RS-422 up
to 250kbps.

SP491CN
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 NSOIC
packages for operation over the commercial temperature range. The
SP491 is available in 14-pin NSOIC packages for operation over the
commercial and industrial temperature ranges.
