The DS485 is a low-power transceiver for RS-485 and RS-422 communication. The device
contains one driver and one receiver. The drivers slew rate allows for operation up to 2.5 Mbps
The transceiver draws 200 μA of supply current when unloaded or fully loaded with the
driver disabled and operates from a single +5V supply.
The driver is short-circuit current limited and is protected against excessive power
dissipation by thermal shutdown circuitry that places the driver outputs into TRI-STATE (High
Impedance state) under fault conditions. The driver ensures a minimum of 1.5V differential output
voltage with maximum loading across the common mode range (VOD3).
The receiver has a failsafe feature that ensures a logic-high output if the input is open
The DS485 is available in 8-pin SOIC and PDIP packages and is characterized for
Industrial and Commercial temperature range operation.
