74HC4072 OR Gate

The  74HC4072 is an OR gateway IC, which consists of 2 separate gateways OR, which are built with C2MOS technology All four inputs are protected against ESD. An ESD stands for Electrostatic Discharge, which is an electrostatic discharge, which is a parameter that if the ICs are not protected against it, it can be damaged by the instantaneous but very high voltage input at the IC input to the IC. To kill Because the human body has a lot of electrostatic charge, it is usually discharged by touching the IC this time, and the IC74HC4072 hampers it due to its protective projections against this phenomenon
