CD4093 IC – Quad 2-Input Schmitt Trigger NAND Gate CD4093

Product Overview: The Texas Instruments (originally Harris Semiconductor) CD4093 / CD4093B is a high-voltage CMOS integrated circuit consisting of four independent Schmitt-trigger circuits. Each circuit functions logically as a 2-input NAND gate but incorporates built-in Schmitt-trigger action on both inputs. The gates switch at different points for positive-going and negative-going signals, providing exceptional noise immunity and wave-shaping capabilities without requiring external components. It is widely used in wave and pulse shapers, high-noise environments, monostable or astable multivibrators, and standard NAND logic applications.
