Clocked Set-Reset Flip-flop

时钟 置位复位 边沿触发器
Example Output
示例输出

When the signal line S goes high, the other line to the NAND gate from the pulse steering circuit must also be high for it to generate a low output. Likewise, a clock pulse must have the reset NAND gate high to receive a high RESET pulse. Therefore all transitions are synchronized to the clock.

当信号线S变高时,从脉冲选择电路到NAND门的另一条线路也必须变高,以便该门产生低电平输出。同样,时钟脉冲必须使复位NAND门处于高电平,以便接收高电平的复位脉冲。因此,所有转换都同步于时钟。

Pulse-Steering Circuit

脉冲定向电路

In the case of the J-K flip-flop, the pulse steering circuit is tied to the output lines past the NAND gate latch. This gives it the toggle action when J and K are both high.

在J-K触发器的情况下,脉冲选择电路连接到NAND门锁存器之后的输出线上。这使得当J和K都为高电平时,它具有翻转作用。

In order to add clock synchronization to a flip-flop, a ciruit is used to apply the clock pulses to the flip-flop. To convert a NAND gate latch to a clocked S/R flip-flop, two NAND gates may be used as above left to enable an input pulse on either the S or R lines to trigger a transition.

为了给触发器添加时钟同步功能,会使用一个电路将时钟脉冲施加到触发器上。要将一个NAND门锁存器转换为时钟控制的S/R触发器,可以如上左图所示使用两个NAND门,以使在S或R线上施加一个输入脉冲以触发状态变化。

The time sequence at right shows the conditions under which the set and reset inputs cause a state change, and when they don't.

右边的时间序列显示了集电极开路输入在引起状态变化的条件以及不引起状态变化的情况。
