4 Input And Gate. Low power dissipation complies with jedec standard no. Sn54ls21 sn74ls21 dual 4 input positive and gates sdls139 april 1985 revised march 1988 post office box 655303 dallas texas 75265 3.
Green wires are connected to inputs a b c d pins 1 2 4 5. However when dealing with boolean expressions and especially logic gate truth tables we do not general use on or off but instead give them bit values which represent a logic level 1 or a logic level 0 respectively. Cd4073b cd4081b and cd4082b and gates provide the system designer with direct implementation of the and function and supplement the existing family of cmos gates.
