The DS36C279 is a low power differential bus/line transceiver designed to meet the requirements of RS-485 Standard for multipoint data transmission. In addition it is compatible with TIA/EIA-422-B.
The sleep mode feature automatically puts the device in a power saving mode when both the driver and receiver are disabled. The device is ideal for use in power conscious applications where the device may be disabled for extended periods of time.
The driver and receiver outputs feature TRI-STATE capability. The driver outputs operate over the entire common mode range of −7V to +12V. Bus contention or fault situations that cause excessive power dissipation within the device are handled by a thermal shutdown circuit, which forces the driver outputs into a high impedance state.
The receiver incorporates a fail safe circuit which ensures a high output state when the inputs are left open.
The DS36C279T is fully specified over the industrial temperature range (−40°C to +85°C).
