一,产品概述(General Description)      

   The CXDR7579 is a reset timer which designed for long reset times. The device has a long fixed delay
of 7.5s ±20% which avoids unplanned reset press.The CXDR7579 operates with 1uA maximal quiescent
current when timer inactive. The CXDR7579 has one input which supports single button resetting required.
It has a single open-drain output, RST,with 0.5mA sink current capability. The DS enablesTest-Mode
operation by forcing /RST low.
