4013
IC 4013腳位問題!麻煩知道的大大進來教一下!
如題:我買了一顆4013
但…他的腳位好像跟74系列的不一樣!
所以…我要知道各腳位是代表什麼!
麻煩說仔細一下!
謝謝!
and are the outputs of the bistable. The logic states of the outputs are always opposite. The bistable is SET when and
and RESET when and . --------------------------------------------------------------------------------The D-type has four inputs. These are: DATA input: This is connected either to a LOW voltage
logic 0
or to a HIGH voltage
logic 1.CLOCK input: The triangle
next to the CLOCK input shows that it is edge-triggered
that is
it responds to sudden changes in voltage
but not to slow changes or to steady logic levels. The CLOCK input of the 4013 D-type bistable is rising-edge triggered
meaning that it responds only to a sudden change from LOW to HIGH.Usually
the CLOCK input is connected to a subsystem which delivers pulses. To test the 4013
you will need to build an astable.SET input: The SET input is normally held LOW. When it is pulsed HIGH
the outputs of the bistable are forced immediately to the SET state
.RESET input: The RESET input is normally held LOW. When it is pulsed HIGH
the outputs of the bistable are forced immediately to the RESET state

假如你使用在高速請看一下適不適用在來用喔。
假如不適用可以換成74的
differential clock input,serial clock input,differential clock input 已支援CLOCK input,RESET input,outputs,bistable,logic states,IC,DATA input,RESET state,HIGH voltage,logic levels
