1. 74LS082. Because 74LS08 is a four-input and gate chip, the output is high only when all the input signals are high.
Therefore, it can implement logical functions with gates. 3. In addition to 74LS08, there are other and gate chips, such as CD4081, CD4082, etc., their input and output characteristics may be different, but they can achieve the logic function of the gate.
74LS11 is a three-input and gate chip.
