The CD4093B consists of four Schmitt-trigger circuits. Each circuit functions as 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 (VT+) and the negative voltage (VT-) is defined as hysteresis voltage (VH).
- Wide supply voltage range: 3.0V to 15V
- Schmitt-trigger on each input
- Noise immunity greater than 50%
- Equal source and sink currents
CD4093 is a very useful chip, as it has a Schmitt-trigger and it is a nand, cmos, low power – ananth.
