1. Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Extended exposure to these
conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute maximum–rated
conditions is not implied.
2. I
absolute maximum rating must be observed.
3. Tested to EIA/JESD22–A114–A.
4. Tested to EIA/JESD22–A115–A.
5. Tested to JESD22–C101–A.
6. Tested to EIA/JESD78.
7. For high frequency or heavy load considerations, see the ON Semiconductor High–Speed CMOS Data Book (DL129/D).

*The HC4538A will function at 2.0 V but for optimum pulse–width stability, V
CC
should be above 3.0 V.
The maximum allowable values of R
x
and C
x
are a function of the leakage of capacitor C
x
, the leakage of the HC4538A, and leakage due to board layout
and surface resistance. For most applications, C
x
/R
x
should be limited to a maximum value of 10 F/1.0 M . Values of C
x
> 1.0 F may cause a
problem during power down (see Power Down Considerations). Susceptibility to externally induced noise signals may occur for R
x
> 1.0 M .
8. Unused inputs may not be left open. All inputs must be tied to a high–logic voltage level or a low–logic input voltage level.
9. Information on typical parametric values can be found in the ON Semiconductor High–Speed CMOS Data Book (DL129/D).
