Yes, my password is: He said he is using 2 inverters.

Discussion in ‘ General Electronics Chat ‘ started by sni9erNov 7, Nov datasheet, 7. Below is my suggestion to fix all of the above: Your schematic is incorrect. It needs to be one or the other. We decided to go back to the origins of AI versus human gaming.

Jul 17, 22, 1, Just to clarify; the counter increments or decrements when the up or down input transitions from 0 to 1. CMOS gates especially have very high input impedances. It will be floating. Quote of the day. Nov 7, 6.

Do you already have an account? You have to show your schematic. Add K pullups on Schmitt Trigger input. Nov 7, 4.


Show the complete schematic of your Schmitt Trigger circuit. Nov 7, 3.

Of course, the one drawback with this circuit is that it requires a double-throw push-button. Nov 8, Rst must be held low, and PE must be held high.

Nov 7, 8. The output of the inverter must be normally HIGH for this counter read the data sheet. The input of the inverter has no DC path to ground. OK I have to apologies for the Rushed Diagram, I thought I had shown clearly, but after a nights sleep looking at it again it actually looks like crap ha-ha anyway I have made some modifications to the schematic, with SGT’s suggestions and the DPDT switch in its current state which I believe without de-bouncing is causing the error.


40192 Up/Down Counter

When the switch first hits one position or the other, the output of one of the inverters is shorted to ground. The values of the resistors are high enough that they present a 50uA load to the inverter output which dagasheet inverter can easily sink. The worst thing you can to do a CMOS input is to leave it floating.

And I might add, don’t be so sure of yourself.
