Quadruple 2-input NAND Schmitt trigger
The HEF4093B consists of four 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.
The difference between the positive voltage (VP) and the
negative voltage (VN) is defined as hysteresis voltage
