About this document

7421 Dual 4-Input AND Gate Datasheet by Kowsik_JS is a document available to read on EtoBox.

The 7421 IC contains two independent four-input AND gates. Each gate performs a logical AND operation on its four binary inputs, outputting a 1 only if all four inputs are 1. The truth table and operation of the four-input AND gate is similar to a two-input AND gate, with the output being the logical AND of the four inputs. The document provides an example calculation and explains that the output will only be 1 if all four inputs are 1.
