The 2-1 AOI gate can be represented by the following boolean equation and truth table: Real world examples of an 2-2 AOI gate are found in the CD4085B, SN74LS51, SN5450 logic ICs (see further below).
[4][5][6] The 2-2 AOI gate can be represented by the following boolean equation and truth table: Real world examples of an 3-3 AOI gate is found in the SN74LS51 logic IC (see further below).
Real world examples of an 4-4 AOI gate is found in the CD4048B logic IC (see further below).
AND-OR-invert (AOI) and OAI gates can be readily implemented in CMOS circuitry.
This results in increased speed, reduced power, smaller area, and potentially lower fabrication cost.
