The HCF4093M is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in SO14 package. Designed by STMicroelectronics, this device consists of four independent 2-input NAND Schmitt trigger circuits. Each circuit functions as a two-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive and negative-going signals, which is a characteristic feature of the Schmitt trigger that provides enhanced noise immunity and transforms slowly changing input signals into sharply defined jitter-free output signals.
