Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. IO absolute maximum rating must be observed.
2. Tested to EIA/JESD22A114A.

The maximum allowable values of Rx and Cx are a function of the leakage of capacitor Cx, the leakage of the HC4538A, and leakage due to board layout
and surface resistance. For most applications, Cx/Rx should be limited to a maximum value of 10 mF/1.0 MW. Values of Cx >1.0 mF may cause a
problem during power down (see Power Down Considerations). Susceptibility to externally induced noise signals may occur for Rx >1.0 MW.
6. Unused inputs may not be left open. All inputs must be tied to a highlogic voltage level or a lowlogic input voltage level.
