Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

4. Tested to JESD22−C101−A.
5. Tested to EIA/JESD78.

*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
mF/1.0
MW. Values of C
x
> 1.0
mF
may cause a
problem during power down (see Power Down Considerations). Susceptibility to externally induced noise signals may occur for R
x
> 1.0 MW.
7. 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.
8. Information on typical parametric values can be found in the ON Semiconductor High−Speed CMOS Data Book (DL129/D).
