Dual D_type Flip Flop
Dual D_type Flip Flop
(OP)
I'm trying to design a simple circuit that detects High/Low inputs and displays pass or failure with a LEDs.
I'm currently using a CD4013BC (Fairchild) in the design as the voltage detector driving Switch mosfets that control the illumination of the Pass/Fail LEDs. The problem I'm having is that if the Input is LOW (0V) and the outut is displayed as "Fail" with the LEDs, I can reset it by Inputing a High (+5V). I only want it to reset when using a reset switch.
If the input is low, I would like the output "Fail" LED to remain lit wether or not a High voltage is set on the input. I only wanted reseted by a reset switch

Is that possible with this chip?

> Reset FF low; Tie D input high, Use Signal as clock
> Rest FF low; Tie D&Clock low; Use Signal as Preset

- Reset FF low; Tie D input high, Use Signal as clock....... Use which Signal? D or Q
- Rest FF low; Tie D&Clock low; Use Signal as Preset.......... Use which Signal? D or Q
