在用高于常见的电源电压(如24V)设计逻辑电路时,可以结合使用标准逻辑系列与一只稳压器,通过电平转换器做接口。另外,如果逻辑并不太复杂,速度也不是非常高,可以用分立元件建立门控电路,直接用当前电压运行。分立元件的AND、OR和NOT功能都相对简单明确,但XOR和XNOR功能通常需要多个AND、OR和NOT基础功能的组合。 When designing logic with higher than usual supply voltages (eg, 24V), a standard logic family can be used in combination with a voltage regulator to interface with a level shifter. In addition, if the logic is not too complicated, the speed is not very high, you can use discrete components to establish gated circuit, directly with the current voltage operation. The AND, OR, and NOT functions of discrete components are relatively straightforward but the XOR and XNOR functions generally require a combination of multiple AND, OR, and NOT basis functions.
