In addition they are compatible with requirements of RS-422. The driver and receiver outputs feature TRI-STATE capability. The driver outputs remain in over the entire common mode range of +12V to −7V. Bus faults that cause excessive power dissipation within the device trigger a thermal shutdown circuit, which forces the driver outputs into the high impedance state. The DS3696A provides an output pin (TS) which reports th...
