Features, Applications

+5V Only Low Power BiCMOS Driver/Receiver Enable Slew Rate Limited Driver for Low EMI (SP483) Low Power Shutdown Mode (SP481 and SP483) RS-485 and RS-422 Drivers/Receivers

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 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 to 250kbps. The SP483 is also equipped with a low power Shutdown mode.

These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
