SP483 / SP485 Low Power Half-Duplex RS-485 Transceivers
FEATURES
• +5V Only
• Low Power BiCMOS
• Driver / Receiver Enable
• Slew Rate Limited Driver for Low EMI (SP483)
• Low Power Shutdown mode (SP483)
• RS-485 and RS-422 Drivers/Receivers DESCRIPTION
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. 1 ABSOLUTE MAXIMUM RATINGS 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. Outputs Logic.-0.3V to (Vcc + 0.5V) Drivers.+/-15V Receivers.-0.3V to (Vcc + 0.5V) Receiver Output Current.+/-95mA
