HCF4093
QUAD 2-input NAND Schmidt trigger
DIP-14
Description
The HCF4093 is a monolithic integrated circuit
fabricated in metal oxide semiconductor
technology available in DIP and SOP packages.
The HCF4093 type consists of 4 schmitt trigger
circuits. Each circuit functions has a 2-input
NAND gate with schmitt trigger action on both
inputs. The gate switches at different points for
positive and negative going signals. The
difference between the positive voltage (V
the negative voltage (V
voltage (V
).

Stressing the device above the rating list ed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any ot her conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may aff ect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
