The DS36C278TM 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 CMOS design offers significant power savings over its bipolar and ALS counterparts without sacrificing ruggedness against ESD damage. The ICC is specified at 500μA maximum. The driver and receiver outputs feature TRI-STATE capability. The driver outputs operate over the entire common mode range of -7 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 the high impedance state. The receiver incorporates a fail-safe circuit which guarantees a high output state when the inputs are left open.
