CD4081 - Quad 2 Input AND Gate IC

The CD4081 quad AND gate IC is a monolithic CMOS IC that is constructed with N- and P-channel enhancement mode transistors. Both the transistors have symmetrical source and sink current capabilities and conform to standard B series output drive. This IC also features buffered outputs that improve transfer characteristics by providing very high gain.

How To Use The CD4081

The CD4081 is a quad two-input AND gate in a DIP-14 package. It is based on the CMOS architecture, which leads to a very low quiescent current. The output is buffered and has symmetric current source/sink capabilities. The output can drive two 74L series inputs or one 74LS series input. The chip is specified for operation at 5V, 10V, and 15V. The outputs of the CD4081 are dependent on the states of the inputs, as shown in the truth table below.
