The CD4093 consists of four Schmitt-trigger circuits. Each circuit functions as a 2-input NAND gate with Schmitttrigger 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). All outputs have equal source and sink currents and conform to standard B-series output drive. 

Features:-

• Wide supply voltage range: 3.0V to 15V 

•  Schmitt-trigger on each input with no external components 

•  Noise immunity greater than 50% 

• Equal source and sink currents 

•  No limit on input rise and fall time 

•  Standard B-series output drive 

•  Hysteresis voltage (any input) TA = 25°C 

   Typical: VDD = 5.0V, VH = 2.2V, VH = 1.5V, VDD = 15V, VDD = 10V, VH = 2.7V 

   Guaranteed:  VH = 0.1 VDD 

Applications:-

• Wave and pulse shapers 

• High-noise-environment systems 

• Monostable multi vibrators 

• Astable multi vibrators 

• NAND logic Ordering Code
