DESCRIPTION
The
SP481, SP483,
and the
SP485
are a family of half-duplex transceivers that meet the
requirements of RS-485 and RS-422. Their BiCMOS design allows low power operation
without sacrificing performance. The
SP481
and
SP485
meet the requirements of RS-485
and RS-422 up to 5Mbps. Additionally, the
SP481
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. The
SP483
is also equipped with a low power
Shutdown mode.
