No, create an account now. The RC filter is configured incorrectly. Oct 21, 15 2. The values of the resistors are high enough that they present a 50uA load to the inverter output which the inverter can easily sink. Normally one would see this feedback circuit using a pair of NAND gates. You May Also Like: And yes, if you are using a switch or push-button to generate a clock you must debounce the switch. When you switch your selector datashwet, there is a moment when the inputs are not connected to anything, i.

The dataasheet of the inverter has no DC path to ground. Oct 2, 17, 5, CMOS gates especially have very high input impedances. Quote of the day. Add K pullups on Schmitt Trigger input. Nov 7, 5. Show the complete schematic of your Schmitt Trigger circuit. It is both your switch your Schmitt-trigger that are not properly wired. The above configuration simply never does that.

Of course, the one drawback with this circuit is that it requires a double-throw push-button. As it is, it can be anything with a floating input. Rst must be held low, and PE must be held high. How to Use the Arduino Joystick Shield v2.

Nov 7, 2. It shows the CU and CD both connected at the same time. Your CD datasheett CU inputs are floating. Conversion of JK Flip-Flops This article teaches you how to convert a given JK flip-flop circuit to other types of flip-flops while verifying the process of conversion.

Nov catasheet, 7. You have to show your schematic. The output of the inverter must be normally HIGH for this counter read the data sheet. Mar 24, 21, 2, Arguably, the situation exists only momentarily. Your schematic is incorrect.

Nov 7, 8. I might also add that the above Schmitt-trigger push button debouncer is not always perfect. When the switch first hits one position or the other, the output of one of the inverters is shorted to ground.

To alleviate this datasgeet, 10k resistors should be added in series with the wires going from the outputs of one inverter to the input of the other inverter. Just to clarify; the counter increments or decrements when the up or down input transitions from 0 to 1. TOP Related Articles.
