74LS123是一种内含两个单稳态功能单元的集成电路,两路独立工作,均可用上升沿或下降沿触发,是一种应用较广的单稳电路。我们利用上、下沿均可
The 74LS123 is an integrated circuit with two monostable functional units that operate independently of each other and can be triggered by a rising or falling edge. This is a monolithic circuit with a wide range of applications. We use the upper and lower edge can be
