RTL逻辑电路 RTL(电阻-晶体管逻辑)是做成集成电路形式的第一种类型的数字逻辑门。如图所示,它与基本的晶体管逻辑电路很相似。每个输入通过电阻连到各自的晶体管上。如果任何一个输入正向达到逻辑1电平,相应的晶体管导通,公共的集电极输出降到逻辑0,给出“或非”运算。串联的基极电阻有助于并联的若干个门的晶体管平分输入电流。 The RTL Logic Circuit RTL (Resistance-Transistor Logic) is the first type of digital logic gate made into an integrated circuit. As shown, it is similar to the basic transistor logic. Each input is connected to the respective transistor through a resistor. If any one of the inputs reaches the logic 1 level in the positive direction, the corresponding transistor is on and the common collector output drops to logic 0, giving a NOR operation. The base resistor in series helps transistors in several gates in parallel divide the input current.
