4093B trigger equivalent, quadruple 2-input nand schmitt trigger.
for the HEF4093B are:
* Wave and pulse shapers
* Astable multivibrators
* Monostable multivibrators.
Fig.10.
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 .
