CD4086 2-Input AND-OR-INVERT Gate

Contents hide

CD4086 is a part of the CD4000 IC series. CD4086 IC is a 4-wide 2-input AND-OR-INVERT gate with an INHIBIT/EXP input and an ENABLE/EXP input. The IC offers a wide array of workable voltages and operating conditions. The IC offers features such as high noise immunity and ESD barring. The CD4086B types are supplied in 14-lead hermetic dual-in-line ceramic packages. The output of CD4086 is always available in TTL, making it easy to interface with other NMOS, CMOS, and TTL devices.

AND Gate

An AND is a simple digital logic gate readily used in digital logic design. An AND gate always yields a logical HIGH when all the inputs to the AND gate are HIGH. If even a single input to the AND Gate is low the will yield a logical LOW.

OR Gate

OR gate is a digital logic gate that yields a HIGH output if even a single gate is at a HIGH Logic. In order to yield a logical LOW from an OR gate, turn any one of the inputs to LOW logic.

NOT Gate

A NOT gate is also reffered to as an invert gate. IF the input to a NOT gate is HIGH, the output will be logical LOW. Similarly, if the input is LOW, the NOT gate will yield a Logical HIGH.
