Where to use the CD4011 IC?

CD4011 is a 2-input 4 NAND gate IC and used in many electronic circuits. CD4011 used for performing the Logic NAND function. When you want to use it as a logic inverter, NAND gates in this chip can be reconfigured to make them NOT gate. So we can make SN54LS00 a four NOT gate chip if necessary. It can be used where high-speed NAND operation is necessary. This chip has less transition times which are needed for high-speed applications. So SN54LS00 can be used in high-frequency systems

Applications of CD4011:

• AV Receivers
• Portable Audio Docks
• Blu-Ray Players
• Home Theater
• MP3 Players or Recorders
• Personal Digital Assistants (PDAs)
