Product Summary
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.
