Product Summary

DESCRIPTION:The SP481, SP483, and the SP485 are a family of half-duplex transceivers that meet therequirements 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.
