... In addition, the large amount of current flowing through either diode will induce the well-known CMOS latch-up condition, which could destroy the device. The LTC1481 output stage of Figure 9 eliminates these problems by adding two Schottky diodes, SD3 and SD4. The Schottky diodes are fabricated by a proprietary modi- fication to the standard N-well CMOS process ...

... In order to guarantee that the part goes into shutdown, DE must be low and RE must be high for at least 600ns simultaneously. If this time duration is less than 50ns the part will not enter shutdown mode. Toggling either will wake the LTC1481 back up within D1 3.5 s. OUTPUT ...
