74192 Up/Down counter problems…

I’ve noticed that you have connected 10K resistor on TTL input pins to trying to pull the logic level down to low. All linear dimensions are in millimeters. Pin 7 of input A 4: Count cycle for ‘ 1 92 and ‘LS 1 92 decade counters is 1 through That only leaves the as the culprit so basically, I probably have it wired incorrectly.

The direction of counting is determined by which count input Is pulsed while the datasbeet count input is high. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Eco Plan – The planned eco-friendly classification: Not recommended for new designs. IC decoder pin diagram Abstract: This symbol is also similar to figure 5.

The operating modes of the ‘ decade counter and the ‘ binary counter are identical, with the only difference being the count sequences as noted in the State Diagram.
