Shouldn't take more than 10 clock cycles to decide.I have pulled out the capacitor and all the leds are on. But i don t know if they will turn off after a while. I will have to observe
Actually i am going to use 3 transistors as a switch for each of the 3 outputs. I am going to use 10 leds in paralell for each of the output. I don`t know now exactly which of the pins will be used. First, I have to select them visually, by the output pattern (flicker or flash).The datasheets of Texas Instruments for CD4xxx ICs have more detail (graphs) than other makes. TI says that if the supply is 9V and the loads are 1.8V red LEDs then typical ICs will have overloaded outputs and poor reliability. If 3.3V blue or white LEDs are used then there is no overloading. Two red LEDs in series can also avoid overloading.
Connecting the Lamp Test pin to the +9 V rail will be fine. But -I think i will try a CD4033Bsince it has the same pinout. The lamp test pin is a very good idea. In the datasheet it says it has to be connected to high-level voltage. what does that mean? Connecting it to the Vss 9v will be enough?
What do you mean "they blink nicely"?
