What the AI looks for in AND Logic Gates

Function code: 74xx08 = quad 2-input AND; 74xx11 = triple 3-input AND; CD4081B = quad 2-input AND; 74LVC1G08 = single gate The part number tells you the input count. A 3-input need is met by the 11, not the 08.
Family for your rail: 74HC08 for 2-6 V CMOS; 74HCT08 for 5 V with TTL/3.3 V inputs; 74LVC08 at 3.3 V; CD4081B up to 18 V Picking the wrong family breaks level compatibility.
Package: DIP-14 for breadboarding; SOIC/TSSOP or SOT-23-5 single gates for PCBs The package must match how you build.

Buying an AND chip when you only need one gate and already have a NAND plus inverter on the board
Floating unused inputs on the spare gates

The pinouts match, but the logic inverts, so the circuit behavior changes.
