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 (VP) and the negative voltage (VN) is defined as hysteresis voltage (VH).
